THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.

THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.

The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequencyenergy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.

The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequencyenergy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.

Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:

Turn the television or radio antenna until the interference stops.

Move the equipment to one side or the other of the television or radio.

Move the equipment farther away from the television or radio.

Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

All Cisco uBR7100 series routers have one power supply with one AC-inputpower receptacle. A power cable connects theAC-inputpower supply to the site AC power source. The router’s main power switch is located next to theAC-inputpower receptacle. Separate power cords are available, depending on the country of operation.

On the side of each chassis are two chassis ground receptacles—choosethe most convenient set for a chassis ground connection for atwo-holegrounding lug, and the other set can provide a mounting location for the cable management bracket. On the back of the chassis, there is a receptacle for electrostatic discharge (ESD) equipment.

Four internal fans draw cooling air into the chassis (back to front) and across internal components to maintain an acceptable operating temperature. There are four environmental sensors for monitoring the cooling air as it leaves the chassis. For more information on environmental monitoring, see the “Environmental Monitoring and Reporting Functions” section on page 6-2.

Caution To ensure the proper flow of cooling air across the internal components, a port adapter must be installed in the port adapter slot. If no port adapter is installed, install a blank port adapter (the product number isMAS-7100-PABLANK=).Slot 5 has a blank face plate. For proper airflow, make sure that a blank faceplate is always installed in slot 5. (The product number isSM-BLANK=).

The modular port adapter slides into the chassis slot and connects directly to the router; there are no internal cables to connect.

The port adapter, fixed cable interface, and fixed LAN interface connect to two peripheral component interconnect (PCI) buses on the router’s backplane that provide a path to packet I/O memory and the system processor. For more information, see the “Peripheral Component Interconnect Buses” section on page 1-14.

Cisco uBR7100 series routers can be installed on a tabletop or in an equipment rack. Rubber feet for tabletop installation are included in the accessory kit that shipped with your router.

A rack-mountandcable-managementkit is also standard equipment included with all Cisco uBR7100 series routers when they are shipped from the factory. The kit provides the hardware needed to mount the router in a standard19-inch,four-postortelco-typeequipment rack. Therack-mountkit also provides the hardware necessary to manage the interface cables attached to the router.

Note Hardware to install the Cisco uBR7100 series in a23-inchor24-inchrack can also be ordered separately (the order number isACS-7100-RMK=).

Chapter 1 Product Overview

Fixed Interface Units

Instructions for installing the router on a tabletop, installing the router in an equipment rack, and attaching the cable-managementbracket are given inChapter 3, “Installing Cisco uBR7100 Series Universal Broadband Routers.”

Fixed Interface Units

The Cisco uBR7100 series universal broadband router contains the following fixed interfaces:

Ethernet/Fast Ethernet LAN Interface, page 1-6

RF Cable Interface, page 1-6

Ethernet/Fast Ethernet LAN Interface

The Cisco uBR7100 series contains a fixed LAN Ethernet/Fast Ethernet autosensing interface with two separately routable 100BASE-TXports. Both ports supportfull-duplexandhalf-duplexoperation, and automatically determine whether the attached network is a10-Mbps10BASE-TEthernet or a100-Mbps,100BASE-TXFast Ethernet network. Each port uses anRJ-45connector with Category 5 unshieldedtwisted-pair(UTP) wiring.

RF Cable Interface

The Cisco uBR7100 series router includes a fixed cable interface card that provides one downstream port and from one to four upstream ports, depending on the model.

On the Cisco uBR7111 and Cisco uBR7114 routers, the cable interface supports the North American DOCSIS channel plan, with a 6 MHz National Television Systems Committee (NTSC) channel width, with a 5 to 42 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.

On the Cisco uBR7111E and Cisco uBR7114E routers, the cable interface supports the EuroDOCSIS channel plan, with an 8 MHz pulse amplitude modulation (PAM) and SECAM channel width, with a 5 to 65 MHz upstream frequency range. The downstream supports the 54 to 858 MHz frequency range with 64 QAM and 256 QAM data rates, while the upstream supports QPSK and 16 QAM data rates.

Two downstream connectors are provided:

DS0 RF—Outputsthe downstream after it has been processed by the router’s integrated upconverter, thereby creating an RF signal suitable for connection to a combiner and transmission on the coaxial cable network.

Peripheral Component Interconnect Buses, page 1-14

Network Processor Card, page 1-15

System LEDs and Reset Button, page 1-18

Chassis Slot and Logical Interface Numbering

In Cisco uBR7100 series routers, the slot number is the location in the chassis where the interface resides and theport number is the physical port associated with that slot. Cisco uBR7100 series router slots are numbered 0 through 5. Interfaces in the Cisco IOS software are identified by a type, slot number, and port number. The number of physical ports depends on the type of modular port adapter or fixed interface. For example, Fast Ethernet 0/1 indicates port 1 on the fixed LAN interface in slot 0.

Slots in the Cisco uBR7100 series are numbered as follows:

Slot 0—FixedLAN (Fast Ethernet) interface

Slot 1—FixedRF interface

Slot 3—Modularport adapter

Note Slots 2, 4, and 5 are not used on the Cisco uBR7100 series router.

Figure 1-5 illustrates the slot placement on Cisco uBR7114 and Cisco uBR7114E routers. The placement on the Cisco uBR7111 and Cisco uBR7111E routers is identical.

MAC Addresses

The Media Access Control (MAC) orhardware address is a standardizeddata-linklayer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The router uses a specific method to assign and control the MAC addresses of its port adapter.

All LAN interfaces (ports) require unique MAC addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the online insertion and removal (OIR) feature requires a different method. For a description of OIR, see the “Online Insertion and Removal” section on page 1-14.

The OIR feature allows you to remove a port adapter and replace it with another identically configured one. If the new port adapter matches the port adapter you removed, the system immediately brings it online.

OL-5916-01

1-13

 

 

 

Chapter 1 Product Overview

Functional Overview

To allow OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the router. Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot.

The MAC addresses for port adapters are assigned to slot 3 in Cisco uBR7100 series routers, not to a particular port adapter. Assigning MAC addresses to the slot and not to the port adapter allows you to remove a port adapter and insert the port adapter into other routers without causing the MAC addresses to move around the network or to be assigned to multiple devices.

Note Storing the MAC addresses for every slot in one central location means the addresses stay with the memory device on which they are stored.

Online Insertion and Removal

The modular port adapter installed in Cisco uBR7100 series routers supports OIR. This function allows you to install and replace a port adapter while the router is operating; you do not need to notify the software or shut down the system power. This provides a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.

The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port adapter in a Cisco uBR7100 series router, see the configuration note that ships with each port adapter.

Each port adapter has a bus connector that connects it to the router. Each connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port adapter is being removed or inserted into the router. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface. For example, when you insert a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter in a Cisco uBR7100 series router, the port adapter pins send signals to notify the system, which then performs as follows:

1.Rapidly scans the system for configuration changes.

2.Initializes all newly inserted port adapters, noting any removed interfaces and placing them in the administratively shutdown state.

3.Brings all previously configured interfaces on the port adapter back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if they were present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought online up to the port count of the original port adapter.

Peripheral Component Interconnect Buses

All interfaces connect to two Peripheral Component Interconnect (PCI) buses on the router that provide a path to packet I/O memory and the network processor. Slots 1 and 3 use PCI bus 0, and slot 0 uses PCI bus 1. The maximum recommended bandwidth points on each PCI bus is 600 points.

Note Slots 2, 4, and 5 are not used in the Cisco uBR7100 series routers.

Functional Overview

Network Processor Card

The network processor card resides inside the chassis and is shown in Figure 1-6 on page 1-16.The network processor card provides the following features:

Senses OIR of the port adapter

Bridges the PCI buses from the interfaces to packet memory

Arbitrates traffic across the PCI buses

Generates the clock signals for the interfaces on each PCI bus

The network processor card also performs the following system management functions:

Sending and receiving routing protocol updates

Managing tables, caches, and buffers

Monitoring interface and environmental status

Providing Simple Network Management Protocol (SNMP) management and the console or Telnet interface

Accounting and switching of data traffic

Booting and reloading images

Managing port adapters (recognition and initialization during OIR)

Note For instructions for removing and replacing memory components on the network processor card, such as the SDRAM DIMMs, refer toMemory Replacement Instructions for the Network Processing Engine or Network Services Engine and Input/Output Controller at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/core/7206/fru/memory/index.htm

The network processor card consists of the following components:

Reduced Instruction Set Computing (RISC) microprocessor running at 175 MHz

Two system controllers—Provideprocessor access to two separate banks of SDRAM and permit devices on both PCI buses to access either SDRAM bank. This means that devices on different PCI buses can access different SDRAM banks simultaneously.

Upgradable memory modules—SDRAMsystem memory defaults to 128 MB and can be upgraded to either 192 MB or 256 MB. (SDRAM packet memory is fixed at 64 MB.) SDRAM memory stores packets received or sent from network interfaces, routing tables, and network accounting applications. The two independent SDRAM memory arrays allow concurrent access by interfaces and the processor. For information about accessing the SDRAM memory modules, refer to the“Upgrading the SDRAM Memory Modules” section on page 6-11.

Note The network processor card contains two SDRAM slots foruser-configurablesystem memory, DIMM 1 and DIMM 2. The amount of memory installed in slot DIMM 1 must be greater than or equal to the memory installed in slot DIMM 2. Slot DIMM 2 is zero for the default memory configuration of

128 MB. Slot DIMM 0 is used only for packet memory and is fixed at 64 MB in the factory.

Cache memory—CiscouBR7100 series routers have two levels of cache: a primary cache that is internal to the microprocessor and a secondary,2-MB(fixed) external cache that provides additionalhigh-speedstorage for data and instructions.

Chapter 2 Preparing for Installation

Safety Guidelines

Safety Guidelines

Any device that uses electricity must be handled carefully; follow these guidelines to ensure general safety:

Keep the chassis area clear and dust-freeduring and after installation.

If removing the chassis cover, put the removed chassis cover in a safe place.

Keep tools away from walk areas where you and others could fall over them.

Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

Wear safety glasses if you are working under any conditions that might be hazardous to your eyes.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

The installation of the router should be in compliance with national and local electrical codes. In the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Canada, Canadian Electrical Code, part I, CC22.1. In other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.

Never attempt to lift an object that might be too heavy for you to lift by yourself.

Always turn all power supplies off (O) and unplug all power cables before opening the chassis.

Always unplug the power cable before installing or removing a chassis.

The AC-poweredrouters ship with athree-wireelectricalgrounding-typeplug, which only fits into agrounding-typepower outlet. This is a safety feature. The equipment grounding should be in accordance with local and national electrical codes.

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.Statement 1024

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Statement 1040

Electrical Equipment Guidelines

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.Statement 4

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.Statement 43

Chapter 2 Preparing for Installation

Safety Guidelines

Follow these guidelines when you work on equipment powered by electricity.

Locate the emergency power-offswitch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn off the power.

Before working on the system, unplug the power cord.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Statement 1

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.Statement 12

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.Statement 1046

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn off power to the system.

If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or other network cabling.

Never install telephone wiring during a lightning storm.

Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.

Chapter 2 Preparing for Installation

Safety Guidelines

Electrostatic Discharge Prevention

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures. Figure 2-1 illustrates how to attach an electrostatic discharge wrist strap.

Always follow ESD-preventionprocedures when you remove and replace components. Ensure that the chassis is electrically connected to earth ground. Wear anESD-preventivewrist strap, ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohms (Mohm).

Chassis Lifting Guidelines

A fully configured Cisco uBR7100 series router weighs approximately 32 pounds (14.5 kg). The chassis is not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared so you can avoid having to move the chassis later to accommodate power sources and network connections.

Whenever you lift the chassis or any heavy object, follow these guidelines:

Always disconnect all external cables before lifting or moving the chassis.

Ensure that your footing is solid, and balance the weight of the object between your feet.

Lift the chassis slowly; never move suddenly or twist your body as you lift.

Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.

Lift the chassis from the bottom; grasp the underside of the chassis exterior with both hands.

Site Requirement Guidelines

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security.

Statement 1017

The environmental monitoring functionality in the router protects the system and components from potential damage from overvoltage and overtemperature conditions. To ensure that normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure the site maintains an ambient temperature of 32°F through 104°F (0°C through 40°C), and keep the area around the chassis as free from dust as is practical.

Planning a proper location for the router and the layout of your equipment rack or wiring closet is essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance difficult. Following are precautions that can help avoid problems during installation and ongoing operation.

Follow these general precautions when planning your equipment locations and connections:

Plan for access to both front and rear panels of the chassis.

Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

Use the show environment command regularly to check the internal system status. The environmental monitor continually checks the interior chassis environment; it provides warnings for high temperature and maximum and minimum voltages and creates reports on any occurrences. If warning messages are displayed, take immediate action to identify the cause and correct the problem.

We recommend keeping the router off the floor and out of any area that tends to collect dust.

Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Ensure that the port adapter (or the blank port adapter) is in place and secure for proper cooling. The fans direct cooling air throughout the chassis interior; a loose component or empty slot can redirect the air flow away from active components.

Rack-MountingGuidelines

The rack-mountinghardware included with router is suitable for standard19-inchequipment racks andtelco-typeracks; brackets for 23and24-inchracks are available separately. To easily access the interface cables while the router is installed in a rack make certain that you have access to the rear of the router.

Before using a particular rack, check for obstructions (such as a power strip) that could impair rack-mountinstallation. If a power strip does impair a rearrack-mountinstallation, remove the power strip before installing the router in the rack, and then replace it after the chassis is installed. As an alternative, you can mount the router on an equipment shelf, provided that the rack dimensions allow you to secure the router to the shelf and the overall configuration permits safe installation and access. However, we recommendrack-mountingthe router.

To use the rack-mountinghardware provided with the router, consider the following guidelines:

To mount the router between two posts or rails using the brackets, the inner clearance (the width between the inner sides of the two posts or rails) must be at least 17 inches (43.18 cm).

The height of the chassis is 3.5 inches (8.89 cm).

When mounting the router in four-postortelco-typeracks, be sure to use all the screws and the brackets provided to secure the chassis to the rack posts.

If you plan to use an equipment shelf, ensure that the shelf is constructed to support the weight and dimensions of the chassis. Figure 2-2 shows the chassis footprint, which you need if you are designing a customized shelf. We recommend that you use therack-mountkit designed for

Cisco uBR7100 series routers.

Chapter 2 Preparing for Installation

Site Requirement Guidelines

When planning your rack installation, consider the following guidelines:

Install the router in an open rack whenever possible. If installation in an enclosed rack is unavoidable, ensure that the rack has adequate ventilation.

An enclosed rack should have louvered sides and a fan to provide cooling air, because heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

Caution To prevent chassis overheating, never install the router in an enclosed rack or room that is not properly ventilated or air conditioned.

Ensure that the rack is not congested, because each unit generates heat. Maintain a minimum clearance of 3 inches (7.62 cm) on the back and front of the chassis for the cooling air inlet and exhaust ports, respectively.

Baffles can isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different configurations.

When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the equipment by itself, if possible. Power off other equipment in the rack to allow the unit under test a maximum of cooling air and clean power.

Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it back near a wall or cabinet for normal operation and pull it out for maintenance (installing or removing a port adapter or connecting cables). Otherwise, allow 19 inches (48.3 cm) of clearance to remove the port adapter.

Install the chassis and external devices to which it will connect in a contiguous stack.

Always install heavier equipment in the lower half of a rack to maintain a low center of gravity and prevent the rack from falling over.

If you use telco-typeracks, be sure that the rack is bolted to the floor and secured, because in these types of installations only one end of the chassis mounts to the two rack posts with the brackets. Ensure that the weight of the chassis does not make the rack unstable.

Provide an adequate chassis ground (earth) connection for your router chassis.

Note We strongly recommend that you provide a chassis ground connection. (See“Attaching the System Ground Connection” section on page 3-5 for instructions.)

In addition to the preceding guidelines, review the precautions for avoiding overtemperature conditions in the following section, “Temperature and Humidity Requirements.” To properly install a

Cisco uBR7100 series chassis in a rack, see the instructions given in “Rack-Mounting the Chassis” section on page 3-3.

Temperature and Humidity Requirements

Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are those within which Cisco uBR7100 series routers continue to operate; however, a measurement that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.

Power Connection Guidelines

Follow these precautions and recommendations when planning power connections to a Cisco uBR7100 series router:

Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.

The AC power supply includes the following features:

Autoselects either 110V or 220V operation.

All units include a 6-foot(1.8-meter)electrical power cord that is appropriate for the country of operation.

Warning This product relies on the building’s installation forshort-circuit(overcurrent) protection. Ensure that the protective device is rated not greater than: 15A minimum, 60VDC.Statement 1005

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.Statement 1024

Use a grounded AC power outlet and install proper grounding to avoid damage from lightning and power surges.

The AC-inputpower supply operates on input voltage and frequency within the ranges of 100 to 240 VRMS and 50/60 Hz without the need for operator adjustments. This power supply also incorporates an active power factor corrector that minimizes the unwanted generation of line current harmonics that can cause overload of site electrical distribution systems.

Note We recommend an uninterruptible power source to protect against power failures at your site. We recommend powering a Cisco uBR7100 series router from a 15A receptacle at the power source.

Chapter 2 Preparing for Installation

Site Requirement Guidelines

Note The Cisco uBR7100 series router installation must comply with all applicable codes and is approved for use with copper conductors only. If installing the router in a central office environment that requires Telcordia grounding, the ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis ground to a central office or other interior ground system should be made with a minimum6-AWG,copper ground conductor.

To satisfy Telcordia grounding requirements, the chassis provides two threaded chassis grounding receptacles, located on the sides near the rear of the chassis, which are intended to be bonded directly to the central offices or other interior ground system. The chassis ground requires 3.5 mm screws, which are included. See “Attaching the System Ground Connection” section on page 3-5 for instructions on attaching the system ground.

Plant Wiring Guidelines

Following are guidelines for setting up the plant wiring and cabling at your site. When planning the location of the new system, consider the distance limitations for signaling, EMC, and connector compatibility, as described in the following sections.

Interference Considerations

When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:

Bad wiring practice can result in radio interference emanating from the plant wiring.

Strong electromagnetic interference (EMI), especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the router, and can even create an electrical hazard by conducting power surges through lines and into equipment. (Review the safety warnings in the “Electrical Equipment Guidelines” section on page 2-3.)

Note To predict and remedy strong EMI, you may also need to consult experts in radio frequency interference (RFI).

If you use twisted-paircable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use ahigh-qualitytwisted-paircable with one ground conductor for each data signal when applicable.

If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse caused by lightning or other high-energyphenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding.

OL-5916-01

 

 

Chapter 2 Preparing for Installation

Site Requirement Guidelines

Distance Limitations and Interface Specifications

The size of your networks and the distances between connections depend on the type of signal, the signal speed, and the transmission media (the type of cabling used to transmit the signals). For example, standard coaxial cable has a greater channel capacity than twisted-paircabling. The distance and rate limits in the following descriptions are the IEEE recommended maximum speeds and distances for signaling; however, you can usually get good results at speeds and distances far greater than these. For example, the recommended maximum rate for V.35 is 2 Mbps, but it is commonly used at 4 Mbps without any problems. If you understand the electrical problems that might arise and can compensate for them, you should get good results with rates and distances greater than those shown here; however, do so at your own risk.

Note We recommend that you do not exceed specified transmission rate and distance limits.

When preparing your site for network connections to a Cisco uBR7100 series router, you must consider a number of factors related to each type of interface:

The type of cabling required for each type (fiber, thick or thin coaxial, foil-twistedpair [FTP], or unshieldedtwisted-pair[UTP] cabling)

Distance limitations for each signal type

The specific cables you need to connect each interface

Any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSUs), or data service units (DSUs)

Cable pinouts if you plan to build your cables

Note The specific interface information you need is contained in the documentation that is shipped with each port adapter.

Also see Appendix C, “Cable Specifications,” for cabling information.

Before installing a Cisco uBR7100 series router, have all additional external equipment and cables on hand. For ordering information, contact a customer service representative.

Ethernet Connections

There are two 10BASE-T/100BASE-TXFast Ethernet ports on the rear panel of the router. Both ports use unshieldedtwisted-pair(UTP) cable. We recommend Category 5 UTP cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the cables used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not. Cables are not included.

Port Adapter WAN Connections

Cisco uBR7100 series routers support a number of port adapters that provide different WAN connection ports on the rear panel of the router. For more information on the cables used with the WAN ports, see the documentation that accompanies the port adapter, as well as Appendix C, “Cable Specifications,”

Chapter 2 Preparing for Installation

Site Requirement Guidelines

Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to ageneral-purposeoutlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both.Statement 1043

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.Statement 1026

Console and Auxiliary Port Considerations

Cisco uBR7100 series routers include an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the access server either locally (with a console terminal) or remotely (with a modem). This section discusses important cabling information to consider before connecting a console terminal (such as PC running terminal emulation software) to the console port or connecting a modem to the auxiliary port.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control using RTS/CTS (Request To Send/Clear To Send) signaling, and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device, ensuring that the receiving device can absorb the data sent to it before the sending device sends more.

When the buffers on the receiving device are full, a message is sent to the sending device to suspend transmission until the data in the buffers has been processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speedtransmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

For detailed information about installing a console terminal and connecting devices to the auxiliary port, see the “Connecting the Console Port and Auxiliary Port” section on page 3-10.For cable and port pinouts, seeAppendix C, “Cable Specifications,”

Console Port Connections

Cisco uBR7100 series routers include an EIA/TIA-232asynchronous serial console port(RJ-45).Depending on the cable and the adapter used, this port will appear as a data terminal equipment (DTE) or data communications equipment (DCE) device at the end of the cable. Your router arrives with cables and adapters to connect a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port.

To connect a PC running terminal emulation software to the console port, use the RJ-45rollover cable with the femaleRJ-45-to-DB-9adapter (labeled TERMINAL). The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware flow control.

Rack-Mountingthe Chassis

Tip If yourack-mountthe router with the back panel forward, attach the system ground connection before yourack-mountthe router. For instructions on how to connect the system ground, see the next section, “Attaching the System Ground Connection.”

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

This unit should be mounted at the bottom of the rack if it is the only unit in the rack.

When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.

If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack. Statement 1006

Tip If using an external upconverter, it should be mounted either above or below the Cisco uBR7100 series router to minimize the length of cable connecting the downstream port to the upconverter.

This section describes how to rack-mountthe chassis in a standardfour-postequipment rack. The router is shipped with19-inchrack-mountbrackets; larger brackets for use with a 23or24-inchrack are available separately (the product number isACS-7100-RMK=).

Chapter 3 Installing Cisco uBR7100 Series Universal Broadband Routers

Attaching the System Ground Connection

Attaching the System Ground Connection

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.Statement 1046

Before you connect power or turn on power to your router, we strongly recommend that you provide an adequate chassis ground (earth) connection for your router’s chassis. This connection is required for a central office that must comply with Telcordia bonding requirements; it is optional but highly recommended for other installations.

Note The Telcordia bonding connections are in addition to the grounding that is required for the AC power connection.

Chassis grounding receptacles for Telcordia bonding connections are provided on each side of the router, near the rear of the chassis.

Note One set of grounding receptacles should be used for the Telcordia bonding ground connection, and the other set can be used for attaching the cable management bracket (seeAttaching the Ground Wire).

To ensure that the chassis grounding connection that you provide is adequate, you need the following parts and tools:

One grounding lug—Musthave two3.5-mmscrew holes that have a0.63-inch(16.002-mm)spacing between them, and a wire receptacle large enough to accept a6-AmericanWire Gauge (AWG) multistrand, copper wire. This grounding lug is provided in the accessory kit.

Two slotted hexhead 3.5 x 7-mmthread-formingmachine screws. These screws are provided in the accessory kit.

One grounding wire—6-AWG,0.162-inch(4.115-mm)diameter, with approximately 0.108 inch (2.743 mm) of insulation, for a total wire diameter of approximately 0.27 inch (6.858 mm). The wire’s length is dependent on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

Flat-bladescrewdriver

Crimping tool large enough to accommodate the diameter of the wire receptacle on your grounding lug

Wire stripper

Attaching the Ground Wire

To attach the grounding lug to the chassis grounding receptacles on the router, use the following procedure:

Step 1 Use the wire stripper to strip one end of the6-AWGwire approximately 0.75 inch (19.05 mm).

Step 2 Insert the6-AWGwire into the wire receptacle on the grounding lug.

Step 3 Use the crimping tool to carefully crimp the wire receptacle around the wire; this step is required to ensure that a proper mechanical connection.

Attaching the Cable-ManagementBracket

Step 7 Connect the opposite end of the grounding wire to the appropriate grounding point at your site to ensure an adequate chassis ground.

Attaching the Cable-ManagementBracket

To install the cable-managementbracket on the router, complete the following steps:

Step 1 Locate the chassis grounding receptacles on the rear sides of the chassis. (SeeFigure 3-8.)

Note Both rear sides of Cisco uBR7100 series chassis have two grounding receptacles. Attach thecable-managementbracket to the two grounding receptacles that were not used to ground the chassis in the“Attaching the System Ground Connection” section on page 3-5.

Step 2 Align thecable-managementbracket to the vacant receptacles. Ensure that the two flanges on the bracket are facing away from the chassis.

Step 3 Thread two 3.5 x7-mmslotted hexhead screws through the bracket and into the chassis. Use aflat-headscrewdriver to tighten the screws. Use tie wraps to secure interface cables to the bracket flanges.

Figure 3-8 shows how to attach thecable-managementbrackets to the Cisco uBR7114 or

Cisco uBR7114E chassis; the Cisco uBR7111 or Cisco uBR7111E chassis is identical.

Connecting to the Network

Connecting to the Network

This section describes how to connect the router to your network. The cables required to connect the router to a network are not provided. For ordering information, contact customer service. For cable product numbers and port pinouts, see Appendix C, “Cable Specifications”.

The router has integrated LAN Fast Ethernet ports and arrives with the modular port adapter already installed, unless you order a port adapter separately as a spare. For information on installing port adapters, see the installation and configuration notes for your port adapter.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Statement 1001

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.Statement 1026

Connecting Upstream and Downstream Ports

The upstream and downstream ports are connected as follows:

DS0 RF outputs the downstream after it has been processed by the Cisco uBR7100 series integrated upconverter. This is an RF signal suitable for output to a combiner.

DS0 outputs the downstream as an IF signal. This signal must be output into an external waveconverter before sending it to a combiner.

US connects the upstream cables to the upstream ports. If an upstream port is not being used, it should remain unconnected.

Use high-qualityRG-59cabling for both the upstream and downstream ports.RG-6cable is not recommended for headend use.

Connecting the Fast Ethernet Ports

The 10BASE-T/100BASE-TXFast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications for10-Mbpsand100-Mbpstransmission over unshieldedtwisted-pair(UTP) cables. These ports also support autosensing and autonegotiation of the proper transmission mode (half duplex or full duplex) with an attached device.

Each Fast Ethernet port has an RJ-45connector that supports standardstraight-throughand crossover Category 3 or Category 5 UTP cable:

Use Category 3 UTP straight-throughcables when connecting a10BASE-Tport to a hub.

Use Category 3 UTP crossover cables when connecting to a PC or other Ethernet device.

Use Category 5 UTP straight-throughcables when connecting100BASE-TXto a hub.

Use Category 5 UTP crossover cables when connecting to a PC or other Ethernet device.

Note Cisco Systems does not supply Category 3 or Category 5 UTPRJ-45cables; these cables are available commercially. For more information, see the“Fast Ethernet Port Cables and Pinouts” section on

page C-4.

To connect the Fast Ethernet port to an Ethernet hub, use the following procedure:

Step 1 Verify that the Ethernet hub is properly connected to the rest of the LAN.

Step 2 Attach the appropriate cable directly to the receptacle on the router. (SeeFigure 3-10.)

Step 3 Attach the network end of the cable to the Ethernet hub or end station. (SeeFigure 3-10.)

Chapter 4 System Startup

Starting the System

Starting the System

After installing the router and connecting cables, start the router as follows:

Step 1 At the back of the router, place the power switch on the power supply in the ON (|) position. The green power (PWR) LED on the router comes on.

Step 2 Listen for the fans; you should immediately hear them operating.

Step 3 During the boot process, observe the system LEDs. The LEDs on the fixed interfaces and the modular port adapter go on and off in irregular sequence. Some may go on, go out, and go on again for a short time.

Step 4 Observe the initialization process. When the system boot is complete (a few seconds), the network processor begins to initialize the interfaces. During this initialization, the LEDs on each port behave differently (most flash on and off).

The enabled LED on each interface goes on when initialization is completed, and the console screen displays a system banner similar to the following:

Restricted Rights Legend

Use, duplication, or disclosure by the Government is subject to restrictions as set forth in subparagraph

(c) of the Commercial Computer Software - Restricted Rights clause at FAR sec. 52.227-19and subparagraph

(c) (1) (ii) of the Rights in Technical Data and Computer Software clause at DFARS sec. 252.227-7013.

cisco Systems, Inc. 170 West Tasman Drive

San Jose, California 95134-1706

Step 5 When you start up the router for the first time, the system automatically enters the setup command facility, which determines which interfaces are installed and prompts you for configuration information for each one. On the console terminal, after the system displays the system banner and hardware configuration, you see the following System Configuration Dialog prompt:

---System Configuration Dialog---

Would you like to enter the initial configuration dialog? [yes/no]:

You have the following options:

Enter yes to proceed with the setup facility to configure the router’s interfaces

Enter no to exit the setup procedure, and instead proceed to use command line interface (CLI) configuration commands to configure the global(system-wide)andinterface-specificparameters.

Note You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.

If the system does not complete each of the steps in the startup procedure, proceed to Chapter 5, “Troubleshooting the Installation,” for troubleshooting recommendations and procedures.

Troubleshooting the Installation

Your Cisco uBR7100 series router went through extensive testing before leaving the factory. However, if you encounter problems starting the router, use the information in this chapter to help isolate the cause of the problems. This chapter contains the following sections:

Troubleshooting Overview, page 5-1

Troubleshooting the Power Subsystem, page 5-4

Troubleshooting the Processor Subsystem, page 5-4

Troubleshooting the Cooling Subsystem, page 5-6

The procedures in this chapter assume that you are troubleshooting the initial system startup, and that your router is in the original factory configuration. If you have removed or replaced components or changed any default settings, the recommendations in this chapter might not apply. Make sure to review the safety warnings listed in the publication that accompanied your Cisco uBR7100 series router before using the troubleshooting procedures in this chapter.

Troubleshooting Overview

This section describes the troubleshooting methods used in this chapter and describes how

Cisco uBR7100 series routers are divided into subsystems for more efficient problem solving.

Figure 5-2 shows the general troubleshooting strategy described in this chapter. Refer to this chart, as necessary, to follow the steps to isolate problems to a specific subsystem; then resolve the problem if possible.

Before You Call for Technical Assistance

If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions. Provide the representative with the following information:

Date you received the router

Chassis serial number

Type of software and release number

Brief description of the problem you are having

Brief explanation of the steps you have taken to isolate and resolve the problem

Maintenance agreement or warranty information

Chapter 5 Troubleshooting the Installation

Troubleshooting Overview

Locating the Serial Number on Your Router

The serial number label is located on the input/output (I/O) side, lower-rightcorner of the chassis.

The serial number format is: 3 letters, 4 numbers, and 4 characters (combination of letters and numbers)

See Figure 5-1 for the location.

Figure 5-1Serial Number Location

Problem Solving Using a Subsystems Approach

The key to solving problems with the system is isolating the problem to a specific subsystem. The first step in solving startup problems is to compare what the system is doing to what itshould be doing. Because a startup problem is usually caused by a single component, it is more efficient to first isolate the problem to a subsystem rather than to troubleshoot each component in the system. For these troubleshooting procedures, consider the following subsystems:

Power subsystem—Includesthe power supply and the external power cable.

Processor subsystem—Includesthe network processing card, the modular port adapter, the service module, and the fixed RF ports. The system memory and management functions reside on the network processing card, and the enabled LED on each port indicates if the port is initialized. A port adapter that is partially installed in the router can cause the system to hang and crash.

Cooling subsystem—Includesthe fans.

The following sections help you isolate a problem to one of these subsystems and direct you to the appropriate troubleshooting section.

Identifying Startup Problems

Startup problems are commonly due to the source power or to a port adapter that is dislodged from the router. Although an overtemperature condition is unlikely at initial startup, the environmental monitoring functions are included in this chapter because they also monitor internal voltages.

When you start up the router for the first time, you should observe the startup sequence described in the “Starting the System” section on page 4-2,which contains a more detailed description of the normal startup sequence.

LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. Use the following descriptions to isolate the problem to a subsystem, and then proceed to the appropriate sections to try to resolve the problem. See Figure 5-2.

If you determine that the power supply is functioning normally and that a fan is faulty, contact a customer service representative. If a fan does not function properly at initial startup, there are no installation adjustments that you should make.

The LEDs on the router should come on as follows:

The power LED (PWR) comes on immediately and indicates that the router is receiving power. This LED comes on during a successful router boot and remains on during normal operation of the router.

If this LED remains off when you start the router, either there is a problem with the power supply (it is damaged or not connected correctly), or the network processing card is not connected properly. Proceed to the “Troubleshooting the Power Subsystem” section on page 5-4.

Chapter 5 Troubleshooting the Installation

Troubleshooting the Power Subsystem

The system ready LED (SYS RDY) comes on after the power LED and indicates that the network processor card is enabled for operation by the system; however, it does not mean that the Fast Ethernet port is functional or enabled. This LED comes on during a successful router boot and remains on during normal operation of the router.

If this LED remains off when you start the router, it is probably a problem with the main processor card. Contact your service representative for technical assistance.

Each enabled LED for the cable interface (EN, DS0 RF, DS0, U0, U1, U2, and U3) comes on initially at power-onand then turns off. The LED then comes on again and remains on when the corresponding port is enabled and configured for operations.

If an enabled LED fails to come on at initial power-on,or if the LED fails to come on and remain on after the port is enabled and configured, proceed to the“Troubleshooting the Port Adapter and Fixed RF Ports” section on page 5-5.

The slot 0 and slot 1 LEDs only come on when the PCMCIA card slot is being accessed by the system. These LEDs remain off during normal operation of the router and do not indicate startup problems.

The initial system banner should be displayed on the console screen.

If it is not displayed, see the “Connecting the Console Port and Auxiliary Port” section on page 3-10 to verify that the terminal is set up correctly and that it is properly connected to the router’s console port.

Troubleshooting the Power Subsystem

Check the following to help isolate a problem with the power subsystem:

Is the power LED (PWR) on?

If yes, the power source is good, and the power supply is functional.

If no, make sure that the power cable is connected at both ends.

If the power LED remains off, and the power switch is set correctly, suspect the power source or the power cable. Turn the switch off, connect the power cable to another power source, if available, and turn the switch back on. If the LED comes on, the problem is the first power source.

If the power LED fails to come on after you connect the power supply to a new power source, replace the power cord, and turn the switch back on. If the LED comes on, return the first power cable for replacement.

If the LED still fails to come on when the power supply is connected to a different power source with a new power cable, the power supply is probably faulty. Contact a service representative for further instructions.

Troubleshooting the Processor Subsystem

The processor subsystem comprises the network processing card and the ports. The system can operate without a port adapter installed as long as none are in partial contact with the connector pins. A port adapter that is partially connected to the router sends incomplete signals to the processor, which faults the Peripheral Component Interconnect (PCI) bus and causes the system to hang. Therefore, first ensure

Chapter 5 Troubleshooting the Installation

Troubleshooting the Processor Subsystem

that the system software has initialized successfully. If not, remove the port adapter and restart the system. If the system then boots, reinsert the port adapter card and, if necessary, troubleshoot the port adapter.

Troubleshooting the Network Processor Card

The procedures in this section assume that the router is in the original factory configuration, and that you have not made changes to your configuration file.

If the system ready LED (SYS RDY) does not come on as expected (see the “When you start up the system by turning the power supply switch to the ON (|) position, the following should occur:” section on page 5-3),check the following items to help isolate the problem:

Do all of the LEDs remain off when the system power switch is turned on?

If the LEDs stay off, first see the “Troubleshooting the Power Subsystem” section on page 5-4 and the “Troubleshooting the Cooling Subsystem” section on page 5-6 to ensure that both the fans and the power supply are functioning properly.

If the power supply and fans appear operational but the system ready or enable LEDs are off, suspect that an improperly connected port adapter has hung the system. Reinsert the port adapter, tighten all captive installation screws, and then restart the system.

Is the system ready LED on?

If yes, the system software has initialized successfully, and the system is operational.

If the system ready LED remains off, the system detected a processor hardware failure. (This LED should be on in normal operation.) Contact a service representative for instructions.

Troubleshooting the Port Adapter and Fixed RF Ports

Check the following to help isolate a problem with a port adapter or fixed RF port:

Are all enabled LEDs on?

If yes, the system is operational.

Are any enabled LEDs off?

If the enabled LED on a port adapter is off, first verify that the port adapter has been enabled and configured for operations. The enabled LED remains off when a port adapter has not been configured and enabled.

If the port has been enabled but its corresponding enabled LED is still off, suspect that the adapter has pulled away from the router. Reseat the adapter in its slot. (You do not have to turn off the system power when removing or replacing port adapters.) After the system reinitializes the interfaces, the enabled LED on the adapter should come on.

If the enabled LED remains off after the above checks, it is likely that the system has detected a processor hardware failure. Contact a service representative for instructions.

Troubleshooting the Cooling Subsystem

Troubleshooting the Cooling Subsystem

Check the following to help isolate a problem with the cooling system:

When you start up the system, do the fans start operating?

To determine if the fans are operating, listen for them. In noisy environments, place your hand on the front of the chassis to feel for air being pushed out of the vents. If necessary, pop off the front bezel to expose the fans and verify that they are operating correctly.

If yes, the power to the fans is good.

If no, there is a problem with the fan or power. (See the “Troubleshooting the Power Subsystem” section on page 5-4.)

The following messages, if displayed, indicate that the system has detected a critical overtemperature condition or out-of-tolerancepower inside the chassis:

Queued messages:

00:01:19:%ENVM-4-ENVWARN:+2.5V measured at +2.5900:01:19:%ENVM-4-ENVWARN:+5.15V measured at +5.31

Although an overtemperature condition is unlikely at initial startup, ensure that heated exhaust air from other equipment is not entering the router’s inlet vent and that there is sufficient clearance around the sides of the chassis to allow cooling air to flow.

The above message could also indicate a faulty component or temperature sensor. Use the show environment orshow environment table command to display the internal chassis environment.

If you experience trouble with the startup that is not resolved with these procedures, manually power off the router and contact a service representative for assistance and further instructions.

Online Insertion and Removal

The port adapter in the Cisco uBR7100 series router supports online insertion and removal (OIR). This function allows you to install and replace the port adapter while the universal broadband router is operating. In most instances, you do not need to shut down system power.

The following is a functional description of OIR; for specific procedures to install, configure, or replace a port adapter, refer to the appropriate port adapter documentation at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/core/12939paf.htm

The port adapter has a bus connector that connects it to the universal broadband router’s midplane. Each midplane connector has a set of tiered pins in three lengths. The pins send specific signals to the system as they make contact with the port adapter. The system assesses the signals it receives and the order in which it receives them to determine if a board is being removed or inserted into the midplane. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface.

For example, when inserting a port adapter, the longest pins make contact with the port adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.

When you remove or insert a port adapter in a Cisco uBR7100 series router, the midplane pins send signals to notify the system, which then performs as follows:

1.Rapidly scans the midplane for configuration changes.

2.Initializes the newly inserted port adapter, noting any removed interfaces and placing them in the administratively shutdown state.

3.Brings all previously configured interfaces on the port adapter back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shutdown state, as if they were present (but not configured) at boot time. If a similar port adapter is reinserted into a slot, its ports are configured and brought online up to the port count of the original port adapter.

Chapter 6 Maintenance

Environmental Monitoring and Reporting Functions

You can remove and replace a port adapter with the same type of component without interrupting the system. To replace a port adapter with a different type of port adapter (for example, replacing a HSSI adapter with an ATM adapter), you must to copy your startup configuration to your running configuration on the Cisco uBR7100 series router to enable the interfaces on the port adapter.

Environmental Monitoring and Reporting Functions

Environmental monitoring and reporting functions are controlled by the network processor and allow you to maintain normal system operation by identifying and resolving adverse conditions that might disrupt operation.

The environmental monitoring functions constantly monitor the internal chassis air temperature and power supply voltages and currents. The power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.

The front and back of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis; we recommend at least 3 inches (7.6 cm) of clearance. Temperature sensors in the router monitor the internal air temperature and send warning messages when the internal air temperature exceeds the specified threshold.

Environmental Monitoring

The environmental monitoring functions use four sensors to monitor the temperature of the cooling air as it moves through the chassis.

If the air temperature exceeds a defined threshold, the router displays warning messages on the console terminal. The system stores the present parameter measurements for both temperature and power voltage in NVRAM so you can retrieve them later.

In addition, the power supply monitors the internal power supply temperature and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If the internal power supply temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.

The environmental monitoring functions use the following levels of status conditions to monitor the system:

Normal—Allmonitored parameters are within normal tolerances.

Warning—Thesystem has exceeded a specified threshold. The system continues to operate, but operator action is recommended to bring the system back to a normal state.

Critical—Anout-of-tolerancetemperature or voltage condition exists. The system continues to operate; however, immediate operator action is required.

Table 6-1 lists the typical temperature thresholds for each network processor type, andTable 6-2 lists the power thresholds for the normal, warning, and critical (powersupply-monitored)levels.

Displaying Environmental Status Reports

Cisco uBR7100 series routers display warning messages on the console if chassis interface-monitoredparameters exceed a desired threshold. You can also retrieve and display environmental status reports with theshow environment,show environment all,show environment last, andshow environment table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows.

Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of other device.

The show environment command displays the current environmental status of the system. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within normal range:

Router# show environment

Flash Memory Card Usage

The Cisco uBR7100 series router has two Personal Computer Memory Card International Association (PCMCIA) slots for Type II flash memory cards. Slot 0 is the lower PCMCIA card slot and slot 1 is the upper PCMCIA card slot.

The following sections describe how to insert, remove, and format a flash memory card

Inserting a Flash Memory Card

To insert a flash memory card in either PCMCIA slot of the Cisco uBR7100 series router, use the following procedure. You do not need to power off the system to insert a flash memory card.

Note To avoid potential problems when inserting spare flash memory cards in your Cisco uBR7100 series universal broadband router, we recommend that you reformat all of your flash memory cards during your regularly scheduled service times. The“Formatting a Flash Memory Card” section on page 6-8 contains instructions that explain how to reformat a flash memory card.

Step 1 Locate the PCMCIA card slots. For proper electrocmagnetic compliance (EMC), the slots have a cover that is secured with a captive screw. (SeeFigure 6-1.)

Step 2 Use aflat-headscrewdriver to loosen the captive screw that secures the protective cover, and lift the protective cover. (SeeFigure 6-2.)

Tip The flash disk memory card slots are labelled slot 0 and slot 1 on the chassis, but the flash disk memory cards themselves are addressed as disk0 and disk1, respectively, when using Cisco IOS commands.

Removing a Flash Memory Card

To remove a flash memory card from either PCMCIA slot:

Step 1 Use aflat-headscrewdriver to loosen the captive screw that secures the protective cover, and lift the protective cover.

Step 2 Press the ejector button on the slot. (SeeFigure 6-4c.)

Step 3 Grasp the card and pull it from the slot and place the card in an antistatic bag.

Formatting a Flash Memory Card

The flash memory card that shipped with your router contains the Cisco IOS software image you need to boot your router. In some cases, you might need to insert a new flash memory card and copy images or backup configuration files onto it. Before you can use a new flash memory card, you must format it. (Use only Type II PCMCIA flash memory cards provided by Cisco.)

Tip To avoid potential problems when inserting spare flash memory cards in your Cisco uBR7100 series router, we recommend that you reformat all your flash memory cards during your regularly scheduled service times.

Caution The following formatting procedure erases all information on the flash memory card. To prevent the loss of important data that might be stored on a flash memory card, proceed carefully. If you want to save the data on a flash memory card, copy the data to a server before you format the card.

Note The following procedure assumes that you have already booted your router.

To format a new flash memory card:

Step 1 Using the procedure described in the“Inserting a Flash Memory Card” section on page 6-5,insert the flash memory card into slot 0. (If slot 0 is not available, use slot 1.)

Step 2 To format the flash memory card, use theformat disk0: (orformat disk1:) command as follows:

Router# format disk0:

All sectors will be

erased, proceed? [confirm]

Enter volume id (up

to 30 characters): MyNewCard

Formatting sector 1

 

Format device disk0

completed

Router#

 

The system counts down the sectors as they are formatted. For example, a 48-MBflash memory card contains 384 sectors, and the display counts backwards from 384 to 1.

When the format routine reaches sector 1, the new flash memory card is formatted and ready to use.

Flash Memory Card Usage

Copying a Bootable Image onto a Flash Memory Card

After you have formatted a new flash memory card, you can copy a bootable image onto it. To copy an image, use the following procedure, which assumes the following:

You have an I/O controller with a good image in the onboard flash memory single in-linememory module (SIMM) so you can start the router.

The bootable image you want to copy to the flash memory card exists on a Trivial File Transfer Protocol (TFTP) server to which you have access (meaning you know its name and have connectivity to it), and at least one interface is available over which you can access this server.

Note To ensure access to a TFTP server, you must configure at least one network interface on your router. For instructions on using this procedure, refer to theCisco uBR7100 Series Software Universal Broadband Router Configuration Guide. See the“Related Documentation” section on page -viii

You know the filename of the image you want to copy onto the flash memory card.

To copy a bootable file (called new.image in the following examples) onto the flash memory card:

 

Step 1

Boot the Cisco uBR7100 series router and allow it to initialize.

 

Step 2

Insert an unformatted flash memory card and format it using the procedure in the “Formatting a Flash

 

 

Memory Card” section on page 6-8. Then proceed to Step 3.

 

 

 

 

 

 

 

 

Note

 

If you have already formatted a flash memory card, you can use it to copy files. However, you

 

 

 

 

 

cannot boot from a flash memory card that was formatted on another type of system. To use the

 

 

 

 

 

card as a boot source, you must first reformat it on the router. To avoid potential problems when

 

 

 

 

 

inserting flash memory cards in your router, we recommend reformatting all your flash memory

 

 

 

 

 

cards during your regularly scheduled service times. The “Formatting a Flash Memory Card”

 

 

 

 

 

section on page 6-8 contains instructions that explain how to reformat a flash memory card.

 

 

 

 

 

Step 3

Copy the new image (new.image) to the flash memory card and make this image the default boot image.

 

 

Then reboot the router using the following series of commands:

Flash Memory Card Usage

Router(config)# boot system flash disk0:new.image

Router(config)# ^z

Router# copyrunning-configstartup-config

Router# reload

Note In this example, the exclamation points (!!!) appear as the file is downloaded, and the “C” characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the flash memory card.

When the system reloads, it boots the new.image file from the flash memory card.

Copying Bootable Images Between Flash Memory Cards

As future releases of Cisco IOS images become available, you will receive these images either as a file booted from a network server, a file on floppy disk, or a file on a flash memory card.

The following scenario describes how to use a newly released image on a flash memory card in a system that has an older image on a flash memory card in slot 0 and a default boot image in the onboard flash memory SIMM.

For this scenario, the filenames are as follows:

The new image on the new flash memory card is new.image.

The old image on the flash memory card in slot 0 (which is addressed as disk0:) is old.image.

The bootable image in onboard flash memory is boot.image.

You will copy the new image from the new flash memory card onto the flash memory card that contains the old image.

Note The scenario assumes that the new image will fit on the flash memory card in slot 0, alongside the old image. If there is not enough available space, use thedelete command to delete files from the flash memory card to make sufficient room for the new image; however, donot delete the image.old file. Then use thesqueeze command to remove these deleted files from the flash memory card. If, after you have deleted files and used thesqueeze command, the two files cannot coexist on the flash memory card in slot 0, remove this card (place it in an antistatic bag and store it in a safe place), then insert the new flash memory card (with the file new.image) in slot 0. Proceed toStep 5 and use theboot system flash slot0:new.image command to designate the file new.image as the default boot image.

Step 1 Boot the Cisco uBR7100 series universal broadband router. By default, the file boot.image is used.

Step 2 Enable the router as follows:

Router> enable

Password: <password>

Step 3 Insert the new flash memory card into slot 1.

Chapter 6 Maintenance

Upgrading the SDRAM Memory Modules

Step 4 Use the following command to copy the file new.image in slot 1 to the flash memory card in slot 0,only if there is enough memory space for the two images to coexist. If there is not enough memory space, proceed toStep 5.

Router# copy disk1:new.image disk0:new.image

Note You can also enter the preceding command ascopy disk1:new.image disk0:.

Step 5 Use the following series of commands to designate the file new.image (which is on the flash memory card in slot 0) as the default boot image:

Router# configure terminal

Router(config)# no boot system

Router(config)# boot system flash disk0:new.image

Router(config)# ^z

Router# copyrunning-configstartup-config

Router# reload

When the system reloads, it boots the file new.image from the flash memory card in slot 0.

Upgrading the SDRAM Memory Modules

The Cisco uBR7100 series router has upgradable memory modules on the network processing card located inside the router. To access these modules, you must remove the top cover of the chassis. Review the safety information before starting this procedure.

Note SDRAM system memory defaults to 128 MB and can be upgraded to either 192 MB or 256 MB. (SDRAM packet memory is fixed at 64 MB.)

Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.

Statement 1003

Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.Statement 1034

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.Statement 4

Warning Hazardous network voltages are present in WAN ports regardless of whether power to the unit is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the unit first.Statement 1026

Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last.Statement 1046

Removing the Chassis Cover

To remove the top cover, use the following procedure:

Step 1 Make sure that you are properly grounded.

Step 2 Removeall power from the chassis.

Step 3 Remove all the network connections.

Step 4 Remove the chassis from the rack (if necessary) and place the it on a tabletop or workbench.

Caution If you are moving the chassis to a workbench or other work area, it is a good idea to reconnect the chassis ground to help prevent ESD damage to the chassis components.

Step 5 Unscrew the four cover screws at the front of the chassis and place the screws in a safe, easily accessible location. SeeFigure 6-5.

Step 6 Using both hands (one on either side of the cover), lift up the front of the cover and pull it towards you until it is clear of the bezel at the rear of the chassis. SeeFigure 6-7.

Step 7 Place the cover in a safe location.

Removing the SDRAM DIMM

To remove the existing DIMM, use the following procedure:

Step 1 Make sure that you are properly grounded.

Step 2 Locate the DIMM and position the chassis so that you are facing the DIMM module you want to remove.

Step 3 Open the DIMM latches on the DIMM to release the DIMM from the socket. (SeeFigure 6-8)The DIMM is under tension in the socket; therefore, the DIMM might be released from the socket with some force.

Caution To prevent ESD damage when working with DIMMs: handle the DIMM by the card edges only, place a removed DIMM on an antistatic mat, and store it in an antistatic container.

Step 5 Place the DIMM in an antistatic container to protect it from ESD damage.

Replacing the SDRAM DIMM

Note The network processor card contains two SDRAM slots foruser-configurablesystem memory, DIMM 1 and DIMM 2.

The amount of memory installed in slot DIMM 1 must be greater than or equal to the memory installed in slot DIMM 2.

Slot DIMM 2 is zero for the default memory configuration of 128 MB.

Slot DIMM 0 is used only for packet memory and is fixed at 64 MB in the factory.

To replace the SRAM DIMM, do the following:

Step 1 Make sure that you are properly grounded.

Step 2 Remove the new DIMM from its antistatic container.

Step 5 When the DIMM is installed, check to see if it is seated properly. If the DIMM appears misaligned, carefully remove it and reseat it in the socket. Push the DIMM firmly back into the socket until first one and then the other latch moves into place.

Step 6 RepeatStep 2 throughStep 5 to replace the second DIMM.

Replacing the Chassis Cover

To replace the cover on the Cisco uBR7100 series router, do the following:

Step 1 Using both hands, carefully hold the cover at an angle and insert it back into the cover tab slots at the rear of the chassis. SeeFigure 6-12.

Step 2 Settle the cover in place making sure that the side tabs are correctly inserted into the side slots.

Step 3 Gently push the cover down until you hear it snap into place.

Step 4 Replace the screws in chassis cover (at the front). Do not overtighten the screws. (The recommended torque is 5 to 7 in. lbs [0.564 to 0.790 nm].)

Step 5 Replace the chassis in the rack (if necessary). See the“Rack-Mounting the Chassis” section on page 3-3.)

Integrated Upconverter Specifications

The integrated upconverter that is installed in the Cisco uBR7100 series chassis meets all DOCSIS and EuroDOCSIS specifications. The upconverter outputs an RF signal and operates in the frequency range of 55 to 858 MHz (band center). The output range is +50 to +63 dBmV at 64 and 256 QAM; the output can go down to +45 dBmV but with degraded power accuracy.

Note The integrated upconverter output is available on the downstream port labeled DS0 RF. The downstream labeled DS0 outputs an IF signal that must be put through an external upconverter before use.

Note On the Cisco uBR7111E and Cisco uBR7114E routers, the DS0 connector is automatically muted when the DS0 RF port is enabled.

Cable Specifications

This appendix contains cable and cable pinout information for the Cisco uBR7100 series universal broadband routers.

Coaxial Cables, page C-1

Console and Auxiliary Port Cables and Pinouts, page C-2

Fast Ethernet Port Cables and Pinouts, page C-4

Note This appendix specifies pinouts only for the pins used. Pins not listed in the tables are not connected.

Coaxial Cables

The coaxial cable used to connect the Cisco uBR7100 series universal broadband routers at the headend should be very high-qualitycable.

We recommend that you use a headend-gradecoaxial cable or aquad-shieldcoaxial cable to connect the cable modem cards to the hybridfiber-coaxial(HFC) network. The center conductor must be straight and extend 1/8 inch (3.2 mm) beyond the end of the connector, and the connector should be securely crimped to the cable. The following headend cables are recommended:

59-seriescable(preferred)—20AWG (0.032 inch/0.81 mm diameter) silver plated,copper-clad,steel center conductor; bonded foil inner shield; 95 percent braid second shield; nonbonded foil third shield; 95 percent braid fourth shield.

59-seriesquadshield—20AWG (0.032 inch/0.81 mm diameter)copper-cladsteel center conductor; bonded foil inner shield; 53 percent braid second shield; nonbonded foil third shield;34–35percent braid fourth shield.

6-seriesquadshield—18AWG (0.0359 inch/0.91 mm diameter)copper-cladsteel center conductor; bonded foil inner shield; 60 percent braid second shield; nonbonded foil third shield;40–42percent braid fourth shield.

Note Any of the three of the coaxial cables listed can be used to connect a Cisco cable interface card to the HFC network; however, the consistent use of59-seriescable is preferred. If you connect a59-seriescable to a cable interface card that was previously connected using6-seriescable, the difference in the center connector diameter might cause intermittent connectivity loss.

Appendix C Cable Specifications

Console and Auxiliary Port Cables and Pinouts

If you use different types of coaxial cable, the following problems can appear:

Damage to Cisco uBR7100 series cable interface card connectors—Cableinterface card connectors are designed for59-seriesor6-seriescable and connectors. Larger cables can damage the connectors.

Poor return loss—High-qualitycable and correct connectors help to ensure an optimal return loss of 16 dB or more.

Caution Poorly shielded coaxial cable may result in undesired signal leakage (egress), interference fromover-the-airsignals (ingress), or crosstalk between cables in close physical proximity.

Console and Auxiliary Port Cables and Pinouts

The router arrives with a console and auxiliary cable kit, which contains the cable and adapters you need to connect a console (an ASCII terminal or PC running terminal emulation software) or modem to the router. The console and auxiliary cable kit includes:

RJ-45-to-RJ-45rollover cable

RJ-45-to-DB-9female data terminal equipment (DTE) adapter labeled TERMINAL

RJ-45-to-DB-25male data communications equipment (DCE) adapter labeled MODEMFigure C-1 shows theRJ-45cable connector.

Identifying an RJ-45Rollover Cable

You can identify a rollover cable by holding the two ends of the cable next to each other, with the tab at the back. The wire connected to the pin on the outside of the lefthand plug should be the same color as as the wire connected to the pin on the outside of the righthand plug, as shown in Figure C-2.

The colored wires at one connector are in the reverse order at the other connector (reverses pins 1 and 8, 2 and 7, 3 and 6, 4 and 5, 5 and 4, 6 and 3, 7 and 2, 8 and 1).

The wires of the straight-throughcable are in the same sequence at both ends of the cable.

Note If your cable was purchased from Cisco Systems, pin 8 is white.

Console Port Cables and Pinouts

Use the RJ-45-to-RJ-45rollover cable andRJ-45-to-DB-9female DTE adapter (labeled TERMINAL) to connect the console port to a PC running terminal emulation software.Table C-1 lists the signals and pinouts for the asynchronous serial console port, theRJ-45-to-RJ-45rollover cable, and theRJ-45-to-DB-9female DTE adapter.

Fast Ethernet Port Cables and Pinouts

The 10BASE-T/100BASE-TXFast Ethernet ports support IEEE 802.3 and IEEE 802.3u specifications for10-Mbpsand100-Mbpstransmission over unshieldedtwisted-pair(UTP) cables. Each Fast Ethernet port on the router has anRJ-45connector to attach to Category 3 or Category 5 UTP cables.

Use a Category 3 UTP crossover cable when connecting 10BASE-Tport to a hub.

Use a Category 3 UTP straight-throughcable when connecting to a PC or other Ethernet device.

Use a Category 5 UTP crossover cable when connecting 100BASE-TXto a hub.

Use a Category 5 UTP straight-throughcable when connecting to a PC or other Ethernet device.

Note Cisco Systems does not supply Category 3 or Category 5 UTPRJ-45cables; these cables are available commercially.

Identifying an RJ-45Crossover Cable

You can identify a crossover cable by comparing the two modular ends of the cable. Hold the cables side-by-sidewith the tab at the back. The first (far left) colored wire (pin 1) at one end of the cable is the third colored wire (pin 3) at the other end of the cable. The second colored wire (pin 2) at one end of the cable is the sixth colored wire (pin 6) at the other end of the cable. Pin 1 wire is white.

Fiber-OpticCables and Connectors

Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not view directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm may pose an eye hazard.Statement 1056

Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.Statement 1051

Use a single-modeor multimodefiber-opticinterface cable to connect your Cisco uBR7100 series router to another router or switch. In general, multimode cables are gray or orange, andsingle-modecables are yellow. For SONET or synchronous digital hierarchy (SDH)single-modeand multimodefiber-opticconnections, use one duplexSC-typeconnector (Figure C-5)or two simplexSC-typeconnectors. (SeeFigure C-6.)

Frequency Allocation Tables

This appendix provides information on broadcast and cable television NTSC and PAL/SECAM standards and frequencies used around the world.

There are three standards for transmitting video. They are defined by the method of encoding color onto a monochrome signal. The methods are defined as:

NTSC—NationalTelevision System Committee

NTSC is the current standard used for analog television in the United States and elsewhere. NTSC supports color television transmission in a 6-MHzchannel bandwidth and has 525 interlaced scan lines. Two fields are interlaced to make one frame with a frame rate of 29.97 frames per second and a field rate of 59.94 fields per second. A fraction (approximately 8 percent) of the available bandwidth is used for signal synchronization between the transmitter and the receiver, giving an effective resolution of 640x480. The aspect ratio, or ratio of picture width to picture height, is 4:3.

PAL—PhaseAlternating Line

PAL is a composite color system similar to NTSC. In PAL, however, the color difference signals alternate phase at the horizontal line rate. PAL video consists of a 625-lineframe, a frame rate of 25 Hz, and a field rate of 50 Hz. As with NTSC, approximately 8 percent of the available bandwidth is used for synchronization yielding an effective resolution of 768x576. The aspect ratio is 4:3. The PAL standard and its variants are used primarily in Europe, Asia, Africa, Australia, Brazil, and Argentina.

SECAM—SEquentialCouleur Avec Memoire

SECAM is a color television broadcasting system using 625 picture lines and a 50-hertz(Hz) field rate, in which the twocolor-differencesignals are transmitted sequentially instead of simultaneously.

NTSC information is covered in Table D-4 on page D-3 andTable D-5 on page D-8.General PAL/SECAM information is covered inTable D-6 on page D-10.Use the information inTable D-1,Table D-2,andTable D-3 on page D-2 to compare analog television standards used around the world.
