Chapter 1 Cisco ASR 903 Router Overview

Cisco ASR 903 Router Features

AC Power Specifications, page 1-5

Redundancy

The Cisco ASR 903 Router chassis includes a slot for an optional redundant power supply. The redundant power supply option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails. The Cisco ASR 903 Router supports current sharing between the power supplies.

If you install a redundant power supply on the Cisco ASR 903 Router, we recommend that you connect each power supply to a separate input power source in order to ensure that the router maintains power in the event of a power interruption caused by an electrical failure, a wiring fault, or a tripped circuit breaker.

Dying Gasp

The Cisco ASR 903 Router DC power supply supports the Dying Gasp feature, which allows the router to provide an input power loss notification to the RSP so that the RSP can send appropriate SNMP traps or OAM messages and update log files on the router. With the DC power supply, the router supports a minimum input power loss detection time of 2 milliseconds (DC) and continued operation of at least 6 milliseconds (DC) after the notification.

Note Continued DC power supply operation may vary for voltages other than+24/-48V.

Status LEDs

LEDs are also provided on each power supply to indicate the status of the input power and the health of the power supply. For more information about the LEDs on the Cisco ASR 903 Router, see Chapter 5, “Troubleshooting.”

DC Power Specifications

The Cisco ASR 903 Router uses a +24/-48Volts Direct Current (VDC)(-19to-72VDC supply tolerance) power supply. The power supply provides 550 W output power for system 12 V power. The power supply is field replaceable,hot-swappable,and operates separately from the fan tray.

The power supply uses a three-positionterminalblock-styleconnector with labeled connections for ground,-24/48V, and +24/48 V. The power supply contains a front panel with mounting screws, a handle for insertion and removal, and two status LEDs. No ON/OFF switch is provided.

The fan tray has the following hardware features:

It provides side-to-sideforced air cooling

It provides redundant fans

It is field replaceable

It contains status LEDs

It contains an alarm port with four external alarm inputs

RSP Modules

The Cisco ASR 903 Router is designed to use up to two RSP modules to handle the data plane, network timing, and control plane functionalities for the router. The RSP configuration allows you to use Cisco IOS software to control chassis management, redundancy, external management, and system status indications on the router.

The following sections describe the Cisco ASR 903 Router RSP:

Supported RSP Features, page 1-7

RSP Redundancy, page 1-7

Chapter 2 Preparing for Installation

Safety Guidelines

Power Supply Considerations

Check the power at your site to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary.

Warning This equipment is designed for connection to TN and IT power systems.Statement 16

Preventing ESD Damage

Warning This equipment needs to be grounded. Use a green and yellow 6 AWG ground wire to connect the host to earth ground during normal use.Statement 383

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When removing and replacing modules, always follow ESD prevention procedures:

Ensure that the router chassis is electrically connected to earth ground.

Wear an ESD-preventivewrist strap, ensuring that it makes good skin contact. To channel unwanted ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

If no wrist strap is available, ground yourself by touching a metal part of the chassis.

When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

When removing a component, use available ejector levers or captive installation screws, if any, to release the bus connectors from the backplane or midplane.

Handle components by their handles or edges only; do not touch the printed circuit boards or connectors.

Place a removed component board side up on an antistatic surface or in a static-shieldingcontainer. If you plan to return the component to the factory, immediately place it in astatic-shieldingcontainer.

Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

Never attempt to remove the printed circuit board from the metal carrier.

Note For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It should be between 1 and 10 Mohm.

Chapter 2 Preparing for Installation

Site Planning

Consideration has been given to the console port wiring and limitations of the cabling involved, according to TIA/EIA-232F.

The Cisco ASR 903 Router Ethernet cabling distances are within limitations.

The equipment rack in which you plan to install the Cisco ASR 903 Router complies with requirements.

In selecting the location of the rack, careful consideration has been given to safety, ease of maintenance, and proper airflow.

Site Selection Guidelines

The Cisco ASR 903 Router requires specific environmental operating conditions. Temperature, humidity, altitude, and vibration can affect the performance and reliability of the router. The following sections provide specific information to help you plan for the proper operating environment.

The Cisco ASR 903 Router is designed to meet the industry EMC, safety, and environmental standards described in the Regulatory, Safety, and Compliance Information for the Cisco ASR 903 Router.

Environmental Requirements

Environmental monitoring in the Cisco ASR 903 Router protects the system and components from damage caused by excessive voltage and temperature conditions. To ensure normal operation and avoid unnecessary maintenance, plan and prepare your site configuration before installation. After installation, make sure that the site maintains the environmental characteristics described in“System Specifications” section on page 2.

Air Flow Guidelines

Cool air is circulated through the Cisco ASR 903 Router by a fan tray located along the right side of the router. Air flow is side-to-side,right to left, as shown in“Cisco ASR 903 Router Chassis Air Flow”.

Figure 2-1Cisco ASR 903 Router Chassis Air Flow

Air exhaust

Room air

344738

The fan trays maintain acceptable operating temperatures for the internal components by drawing in cool air through the vents, and circulating the air through the chassis.

The following guidelines will help you plan your equipment rack configuration:

To ensure adequate air flow through the equipment rack, we recommend that you maintain a clearance of at least 80 mm on each side of the rack at all times.

If airflow through the equipment rack and the routers that occupy it is blocked or restricted, or if the ambient air being drawn into the rack is too warm, an overtemperature condition can occur within the rack and the routers that occupy it.

The site should also be as dust-freeas possible. Dust tends to clog the router fans, reducing the flow of cooling air through the equipment rack and the routers that occupy it, thus increasing the risk of an overtemperature condition.

Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. Heat that is generated by the equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

When mounting a chassis in an open rack, ensure that the rack frame does not block the side intakes and the exhaust fans.

When rack-installedequipment fails, especially equipment in an enclosed rack, try operating the equipment by itself, if possible. Power off all other equipment in the rack (and in adjacent racks) to give the router maximum cooling air and clean power.

Avoid locating the Cisco ASR 903 Router in a location in which the chassis air intake vents may draw in the exhaust air from adjacent equipment. Consider how the air flows through the router; the airflow direction is side to side, with ambient air drawn in from the vents located on the front right of the chassis.

Air Flow Guidelines for Enclosed Rack Installation

To install a Cisco ASR 903 Router in a 4-postenclosed cabinet, the front and rear doors of the cabinet must be removed or be perforated with a minimum of 65% open area (70% for ETSI 800mm racks).

If you are mounting the chassis in a 4-postenclosed cabinet, ensure that you have a minimum of 6 inches (15.24 cm) of clearance on each side of the chassis.

Floor Loading Considerations

Ensure that the floor under the rack supporting the Cisco ASR 903 Routers is capable of supporting the combined weight of the rack and all the other installed equipment.

To assess the weight of a fully configured Cisco ASR 903 Router, refer to “System Specifications” section on page 1-2.

For additional information about floor loading requirements, consult GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.

Site Power Guidelines

The Cisco ASR 903 Router has specific power and electrical wiring requirements. Adhering to these requirements ensures reliable operation of the system. Follow these precautions and recommendations when planning your site power for the Cisco ASR 903 Router:

The redundant power option provides a second, identical power supply to ensure that power to the chassis continues uninterrupted if one power supply fails or input power on one line fails.

In systems configured with the redundant power option, connect each of the two power supplies to a separate input power source. If you fail to do this, your system might be susceptible to total power failure due to a fault in the external wiring or a tripped circuit breaker.

To prevent a loss of input power, be sure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and the breakers.

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.

Provide proper grounding to avoid personal injury and damage to the equipment due to lightning striking power lines or due to power surges. The chassis ground must be attached to a central office or other interior ground system.

Caution This product requiresshort-circuit(overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.

Note The Cisco ASR 903 Router installation must comply with all the applicable codes and is approved for use with copper conductors only. 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 must be made with a 6 AWG gauge wire, copper ground conductor at a minimum.

This section contains guidelines for wiring and cabling at your site. When preparing your site for network connections to the Cisco ASR 903 Router, consider the type of cable required for each component, and the cable limitations. Consider the distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility. Possible cable types are fiber, thick or thin coaxial, foil twisted-pair,or unshieldedtwisted-paircabling.

Also consider any additional interface equipment you need, such as transceivers, hubs, switches, modems, channel service units (CSU), or data service units (DSU).

Before you begin, read these important notes about cabling:

The T1/E1 interface module for the Cisco ASR 903 Router uses a high-densityconnector that requires the use of a T1/E1 interface cable and acustomer-providedpatch panel. For more information, see“Connecting T1/E1 cables” section on page 3-40.

Shielded cables must be used to connect to the DB-25alarm connector on the fan tray in order to comply with FCC/EN55022/CISPR22 Class A emissions requirements. For information about the fan tray alarm port, see“Connecting the Fan Tray Alarm Port” section on page 3-42.

Before you install the Cisco ASR 903 Router, have all the additional external equipment and cables on hand. For information about ordering, contact a Cisco customer service representative.

Chapter 2 Preparing for Installation

Site Planning

The extent of your network and the distances between the network interface connections depend in part on the following factors:

Signal type

Signal speed

Transmission medium

The distance and rate limits referenced in the following sections are the IEEE-recommendedmaximum speeds and distances for signaling purposes. Use this information as a guideline in planning your network connections prior to installing the Cisco ASR 903 Router.

If wires exceed the 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.

Asynchronous Terminal Connections

The RSP provides a console port to connect a terminal or computer for local console access. The port has an RJ45 connector and supports RS-232asynchronous data with distance recommendations specified in the IEEERS-232standard.

Interference Considerations

When wires are run for any significant distance, there is a risk that stray signals will be induced on the wires as interference. If interference signals are strong, they can cause data errors or damage to the equipment.

The following sections describe sources of interference and how to minimize its effects on the Cisco ASR 903 Router system.

Electromagnetic Interference

All equipment powered by AC current can propagate electrical energy that can cause EMI and possibly affect the operation of other equipment. The typical sources of EMI are equipment power cords and power service cables from electric utility companies.

Strong EMI can destroy the signal drivers and receivers in the Cisco ASR 903 Router and even create an electrical hazard by causing power surges through the power lines into installed equipment. These problems are rare but could be catastrophic.

To resolve these problems, you need specialized knowledge and equipment that could consume substantial time and money. However, you can ensure that you have a properly grounded and shielded electrical environment, paying special attention to the need for electrical surge suppression.

For information about the electrode magnetic compliance standards supported on the

Cisco ASR 903 Router, see Regulatory Compliance and Safety Information for the

Cisco ASR 903 Router.

Radio Frequency Interference

When electromagnetic fields act over a long distance, radio frequency interference (RFI) may be propagated. Building wiring can often act as an antenna, receiving the RFI signals and creating more EMI on the wiring.

 

Cisco ASR 903 Router Hardware Installation Guide

2-14

OL-25178-04

Chapter 2 Preparing for Installation

Site Planning

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.

Lightning and AC Power Fault Interference

If signal wires exceed the recommended cabling distances, or if signal wires pass between buildings, you should consider the effect that a lightning strike in your vicinity might have on the

Cisco ASR 903 Router.

The electromagnetic pulse (EMP) generated by lightning or other high-energyphenomena can couple enough energy into unshielded conductors to damage or destroy electronic equipment. If you have previously experienced such problems, you should consult with RFI and EMI experts to ensure that you have adequate electrical surge suppression and shielding of signal cables in your Cisco ASR 903 Router operating environment.

Rack-MountingGuidelines

The following sections provide guidelines for rack-mountingthe Cisco ASR 903 Router:

Precautions for Rack-Mounting, page 2-15

Rack Selection Guidelines, page 2-15

Equipment Rack Guidelines, page 2-16

Precautions for Rack-Mounting

The following rack-mountguidelines are provided to ensure your safety:

Do not move large racks by yourself. Due to the height and weight of a rack, a minimum of two people are required to accomplish this task.

Ensure that the rack is level and stable before extending a component from the rack.

Ensure that proper airflow is provided to the components in the rack.

Do not step on or stand on any component or system when servicing other systems or components in a rack.

When mounting the Cisco ASR 903 Router 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.

Rack Selection Guidelines

The Cisco ASR 903 Router can be mounted in most two-postorfour-post,19-inchequipment racks that comply with the Electronic Industries Association (EIA) standard for equipment racks(EIA-310-D19-inch).The rack must have at least two posts with mounting flanges to mount the chassis.

Caution When mounting a chassis in any type of rack equipment, ensure that the inlet air to the chassis does not exceed 65 degrees C.

Chapter 2 Preparing for Installation

Site Planning

The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mountinghardware included with the chassis is suitable for most19-inchequipment racks.

Consider installing the Cisco ASR 903 Router in a rack with the following features:

Network Equipment Building System (NEBS) compliant, 19-inch(48.3 cm) wide rack.

EIA or European Telecommunications Standards Institute (ETSI) hole patterns in the mounting rails. The required mounting hardware is shipped with the Cisco ASR 903 Router. If the rack that you plan to install the system in has metric-threadedrails, you must provide your ownmetric-mountinghardware.

Perforated top and open bottom for ventilation to prevent overheating.

Leveling feet for stability.

Note The Cisco ASR 903 Router shouldnot be installed in an enclosed rack because the chassis requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the router in any type of enclosedrack—even with the side doors removed—coulddisrupt the air flow, trap heat next to the chassis, and cause an overtemperature condition inside the router. If you use an enclosed rack, ensure that there are air vents on all sides of the rack and there is proper ventilation.

Equipment Rack Guidelines

The placement of the rack can affect personnel safety, system maintenance, and the system’s ability to operate within the environmental characteristics described in the “System Specifications” section on page 1-2.Choose a proper location for the Cisco ASR 903 Router by following the following guidelines.

Locating for Safety

If the Cisco ASR 903 Router is the heaviest or the only piece of equipment in the rack, consider installing it at or near the bottom to ensure that the rack’s center of gravity is as low as possible.

For additional information about the proper placement of electronic equipment, consult the document

GR-63-CORE,Network Equipment Building System (NEBS) Requirements: Physical Protection.

Locating for Easy Maintenance

Keep at least 3 feet of clear space at the front and back of the rack. This space ensures that you can remove the Cisco ASR 903 Router components and perform routine maintenance and upgrades easily.

Avoid installing the Cisco ASR 903 Router in a congested rack and consider how routing of cables from other pieces of equipment in the same rack could affect access to the router cards.

The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside the chassis.

Allow the following clearances for normal system maintenance:

At the top of the chassis—Atleast 3 inches (7.6 cm)

Sides of the chassis—3to 4 ft (91.44 cm to 121.92 cm)

To avoid problems during installation and ongoing operations, follow these general precautions when you plan equipment locations and connections:

OL-25178-04

Chapter 2 Preparing for Installation

Site Planning

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

Keep the Cisco ASR 903 Router off the floor and out of areas that collect dust.

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

Locating for Proper Airflow

Ensure that the Cisco ASR 903 Router location has enough airflow to keep the system operating within the environmental characteristics and the air temperature is sufficient to compensate for the heat dissipated by the system. For more information, see “Air Flow Guidelines” section on page 2-11.

Chassis-LiftingGuidelines

The chassis is not intended to be moved frequently. Before you install the system, ensure that your site is properly prepared so that you can avoid having to move the chassis later to accommodate power sources and network connections.

Two or more people are required to lift the chassis. Each time you lift the chassis or any heavy object, follow these guidelines:

Never attempt to lift the chassis by yourself. Because of the size and weight of the chassis, use at least two people to safely lift and move it without causing injury to yourself or damaging the equipment.

Ensure that your footing is solid, and balance the weight of the chassis 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 back muscles.

Do not remove installed components from the chassis.

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

Warning To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Lift the unit only by using handles that are an integral part of the chassis, or by grasping the chassis underneath its lower edge.Statement 163

Perform the following to lift a chassis:

Step 1 Each person should stand on either side of the chassis and place one hand under the air intake at the bottom front of the chassis.

Step 2 With the other hand, grasp the top rear of the chassis under the air exhaust, and carefully lift the chassis.

Step 4 Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the module faceplate.

Caution If the top slot already has an RSP module installed, and you install a second RSP module in the slot below it, be careful not to damage the EMI gasket of the bottom RSP module against the ejector levers of the top RSP during insertion.

Step 5 While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.

Step 6 Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5in.-lb(.62N-m).

Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.

Chapter 3 Installing the Cisco ASR 903 Router

RSP Installation

Step 7 Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening space for the new or replacement module.

Note If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, which reduces the size of the opening and makes it difficult to install the new module.

Note Blank module filler plates (Cisco part numberA900-RSPA-BLANK)should be installed in any empty chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.

Note When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling sufficient to allow for fan tray removal.

Removing an RSP Module

Before you remove an RSP from the router, you should save the current configuration using the write {host file | network | terminal} command. This saves you time when bringing the module back online.

If the module is running Cisco IOS software, save the current running configuration by entering the copy running-config startup-config command.

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

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

To remove an RSP module, perform the following steps:

Step 1 Disconnect any cables attached to the ports on the module.

Step 2 Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures that the space created by the removed module is maintained.

Note If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, which in turn reduces the size of the opening and makes it difficult to remove the module.

Step 3 Loosen the two captive installation screws on the module you plan to remove from the chassis.

Step 4 Place your thumbs on the ejector levers (seeFigure 3-14)and simultaneously rotate the ejector levers outward to unseat the module from the backplane connector.

Chapter 3 Installing the Cisco ASR 903 Router

RSP Installation

Step 5 Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.

Caution To prevent ESD damage, handle modules by the carrier edges only.

Step 6 Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.

Step 7 Install blank module filler plates (Cisco part numberA900-RSPA-BLANK)in empty slots, if any.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.Statement 1029

Hot-Swappingan RSP Module

The Cisco ASR 903 Router provides a feature that allows you to remove and replace a redundant RSP module without powering down the router. This feature, called hot-swappingor OIR, allows you to remove and replace a redundant module without disrupting router operation.

When two redundant modules are installed in the router, only one of the modules is active. The other one runs in standby mode, ready to take over processing if the active module fails.

When you remove or insert a redundant module while the router is powered on and running, the router does the following:

1.Determines if there is sufficient power for the module.

2.Scans the backplane for configuration changes.

3.Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.

4.Places any previously configured interfaces on the module 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 unconfigured) at boot time. If you insert the same type of module into a slot, its ports are configured and brought online up to the port count of the original module.

The router runs diagnostic tests on any new interfaces and the test results indicate the following:

If the tests pass, the router is operating normally.

If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.

If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Use the following guidelines when performing an OIR on an IM:

Allow at least 2 minutes for the system to reinitialize before inserting a new IM.

Avoid inserting a new IM during bootup until the active and standby RSPs have reached an OK state.

Caution Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.

Removing an Interface Module

Step 1 To remove an interface module, disconnect all the cables from each interface module.

Step 2 Loosen the locking thumbscrews on both sides of the interface module.

Step 3 Slide the interface module out of the router slot by pulling on the handles. If you are removing a blank filler plate, pull the blank filler plate completely out of the router slot using the captive screws.

Hot-Swappingan Interface Module

The Cisco ASR 903 Router provides a feature that allows you to remove and replace an interface module without powering down the router. This feature, called hot-swappingor OIR, allows you to remove and replace a redundant module without disrupting router operation.

Note The Cisco ASR 903 Router does not supporthot-swappingan interface module with another module of a different type. For example, you cannot swap an SFP Gigabit Ethernet module with a copper Gigabit Ethernet module without disrupting router operation.

Note If you perform OIR on an interface module and move the module to a different slot, the router does not retain the module configuration; you must reconfigure the interface module.

When you remove or insert a redundant module while the router is powered on and running, the router does the following:

1.Determines if there is sufficient power for the module.

2.Scans the backplane for configuration changes.

3.Initializes the newly inserted module. In addition, the system notes any removed modules and places those modules in the administratively shutdown state.

4.Places any previously configured interfaces on the module back to the state they were in when they were removed.

The router runs diagnostic tests on any new interfaces and the test results indicate the following:

If the tests pass, the router is operating normally.

If the new module is faulty, the router resumes normal operation but leaves the new interfaces disabled.

If the diagnostic tests fail, the router stops operating, which usually indicates that the new module has a problem in the bus and should be removed.

Chapter 3 Installing the Cisco ASR 903 Router

Installing the Power Supply

Installing the Power Supply

The Cisco ASR 903 Router router provides the choice of two different power supplies:

DC power—19.2VDCto-72VDC

The DC power supply uses 3 position terminal block-styleconnector with positive latching/securing and labeled connections for +24/48V, GRD,-24/48V.The terminal block connector is of suitable size to carry the appropriate AWG wire size to handle the input current of the power supply. No ON/OFF switch is provided.

AC power—85VACto 264VAC

The AC power supply has an IEC 320-typepower receptacle and a 15 Amp service connector. You can use standard right angle power cords with the AC power supply. The power supply includes a power cord retainer. No ON/OFF switch is provided.

Each power supply provides a single primary input power connection. You can install dual power supplies for redundancy.

Warning Read the installation instructions before connecting the system to the power source.Statement 10

Note Products that have an AC power connection are required to have an external surge protective device (SPD) provided as part of the building installation to comply with the TelcordiaGR-1089NEBS standard for electromagnetic compatibility and safety.

Caution Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the chassis can deform or damage the handles.

The following sections describe the Cisco ASR 903 Router power supplies:

Preventing Power Loss, page 3-17

Power Connection Guidelines, page 3-18

Installing the DC Power Supply, page 3-19

Removing and Replacing the DC Power Supply, page 3-24

Installing the AC power Supply, page 3-25

Preventing Power Loss

Use the following guidelines to prevent power loss to the router.

To prevent loss of input power, ensure that the total maximum load on each circuit supplying the power supplies is within the current ratings of the wiring and breakers.

In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems like the Cisco ASR 903 Router, which can have substantial current draw fluctuations due to bursty data traffic patterns.

Warning This product requiresshort-circuit(overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations.Statement 1045

Guidelines for DC-PoweredSystems

Basic guidelines for DC-poweredsystems include the following:

Each chassis power supply should have its own dedicated input power source. The source must comply with the safety extra-lowvoltage (SELV) requirements in the UL 60950, CSA 60950, EN 60950, and IEC 60950 standards.

The circuit must be protected by a dedicated two-polecircuit breaker. The circuit breaker should be sized according to the power supply input rating and local or national code requirements.

The circuit breaker is considered the disconnect device and should be easily accessible.

The system ground is the power supply and chassis ground.

Do not connect the DC return wire to the system frame or to the system grounding equipment.

Use the grounding lug to attach a wrist strap for ESD protection during servicing.

Guidelines for AC-PoweredSystems

Basic guidelines for AC-poweredsystems include the following:

Each chassis power supply should have its own dedicated branch circuit.

The circuit breaker should be sized according to the power supply input rating and local or national code requirements.

The AC power receptacles used to plug in the chassis must be the grounding type. The grounding conductors that connect to the receptacles should connect to protective earth ground at the service equipment.

Step 5 Tighten the captive installation screws of the power supply. The recommended maximum torque is 5.5in.-lb(.62N-m).

If you are installing a redundant DC power supply, repeat these steps for the second power source.

Installing the Terminal Block

Perform the following procedure to install the terminal block:

Step 1 Locate the terminal block plug.

Step 2 Use awire-strippingtool to strip the ends of each of the two wires coming from theDC-inputpower source to 0.27 inch (6.6 mm) ± 0.02 inch (0.5 mm) and the wire for grounding. Do not strip more than 0.29 inch (7.4 mm) of insulation from the wire. Stripping more than the recommended amount of wire can leave behind exposed wire from the terminal block plug after installation.

Step 3 Identify the ground, positive, and negative feed positions for the terminal block connection. The recommended wiring sequence is:

a.Ground lead wire (right)

b.Negative (-)lead wire (left)

c.Positive (+) lead wire (middle)

Note You cannot use the USB port and the EIA port concurrently. See“Connecting to the Auxiliary Port” section on page 3-33.When the USB port is used it takes priority over the RJ45 EIA port.

Note The USB TypeA-to-TypeA cable is not included with the Cisco ASR 903 Router; it is ordered separately.

Step 2 Connect the end of the cable with theDB-9connector (or USBType-A)to the terminal or PC. If your terminal or PC has a console port that does not accommodate aDB-9connector, you must provide an appropriate adapter for that port.

Step 3 To communicate with the router, start a terminal emulator application, such as Microsoft Windows HyperTerminal. This software should be configured with the following parameters:

9600 baud

8 data bits

no parity

1 stop-bit

no flow control

Chapter 3 Installing the Cisco ASR 903 Router

Connecting the Cisco ASR 903 Router to the Network

Connecting a Management Ethernet Cable

When using the Ethernet Management port in the default mode (speed-autoandduplex-auto)the port operates inauto-MDI/MDI-Xmode. The port automatically provides the correct signal connectivity through theAuto-MDI/MDI-Xfeature. The port automatically senses a crossover orstraight-throughcable and adapts to it.

However, when the Ethernet Management port is configured to a fixed speed (10 or 100 Mbps) through command-lineinterface (CLI) commands, the port is forced to MDI mode.

When in a fixed-speedconfiguration and MDI mode:

Use a crossover cable to connect to an MDI port

Use a straight-throughcable to connect to anMDI-Xport

Warning To comply with the TelcordiaGR-1089NEBS standard for electromagnetic compatibility and safety, connect the Management Ethernet ports only tointra-buildingor unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. Theintra-buildingport(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use asintra-buildinginterfaces only (Type 2 or Type 4 ports as described inGR-1089-CORE)and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Installing and Removing SFP and XFP Modules

The Cisco ASR 903 Router supports a variety of SFP and XFP modules, including optical and Ethernet modules. For information on how to install and remove SFP and XFP modules, see the documentation for the SFP or XFP module at

http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html

For information about inspecting and cleaning fiber-optic connections, see http://www.cisco.com/en/US/partner/tech/tk482/tk876/technologies_white_paper09186a0080254eba.s html

Caution We recommend that you wait 30 seconds between removal and insertion of an SFP on an interface module. This time is recommended to allow the transceiver software to initialize and synchronize with the standby RSP. Changing an SFP more quickly could result in transceiver initialization issues that disable the SFP.

Connecting a USB Flash Device

To connect a USB flash device to the Cisco ASR 903 Router, insert the memory stick in the USB port labeled MEM. The Flash memory module can be inserted in only one way, and can be inserted or removed regardless of whether the router is powered up or not.

Figure 3-24 shows the USB port connector on the Cisco ASR 903 Router.

For information about the pinout of the cable connecting the T1/E1 interface to the rear of the patch panel, see the “T1/E1 Port Pinout” section on page 5-4.

RJ45 Cable Pinouts

T1 lines from individual subscribers are attached to RJ45 connectors on the front of the 24-portpatch panel. Each RJ45 port accommodates an individual T1 subscriber line.

For the T1/E1 ports, see the “T1/E1 Port Pinout” section on page 5-4.

Connecting Cables to the Patch Panel

If you are connecting two T1/E1 interfaces to each other, you must cable both interfaces’ patch panels together using a T1 cross-overcable or a T1straight-throughcable. Use shielded cables. The type of cable you use(cross-overorstraight-through)depends on how the T1/E1 interfaces are cabled to their patch panels:

If both T1/E1 interfaces are connected to their patch panels in the same manner (TX to Transmit and RX to Receive, or TX to Receive and RX to Transmit), use a T1 cross-overcable to connect the patch panels.

If both T1/E1 interfaces are connected to their patch panels in a different configuration (TX to Transmit and RX to Receive on one interface, and TX to Receive and RX to Transmit on the other interface), use a T1 straight-throughcable (standard RJ45 patch cable) to connect the patch panels.

Warning To comply with the TelcordiaGR-1089NEBS standard for electromagnetic compatibility and safety, connect the T1/E1 ports only tointra-buildingor unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. Theintra-buildingport(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring.

Connecting the Fan Tray Alarm Port

The fan tray includes an alarm port that maps to 4 dry contact alarm inputs.

The pins on the alarm port are passive signals and can be configured as Normally Open (an alarm generated when current is interrupted) or Normally Closed (an alarm is generated when a circuit is established) alarms. You can configure each alarm input as critical, major, or minor. An alarm triggers alarm LEDs and alarm messages. The relay contacts can be controlled through any appropriate third-partyrelay controller. The open/close configuration is an option controlled in IOS.

Warning To comply with the TelcordiaGR-1089NEBS standard for electromagnetic compatibility and safety, connect the alarm ports only tointra-buildingor unexposed wiring or cable. The intrabuilding cable must be shielded and the shield must be grounded at both ends. Theintra-buildingport(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use asintra-buildinginterfaces only (Type 2 or Type 4 ports as described inGR-1089-CORE)and require isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP wiring.

Only Pins 1, 2, 4, 6, and 8 are available for customer use. The remaining pins are for Cisco manufacturing test, and should not be connected. Use a shielded cable for connection to this port for EMC protection. Table 5-4 summarizes the pinouts on the alarm port inChapter 5, “Troubleshooting.”

Step 1 Attach an RJ45 cable to the alarm port.

Step 2 Attach the other end of the RJ45 cable to the relay controller.

For information about how to map alarm inputs to critical, major, and minor alarm conditions, see the

Cisco ASR 903 Router Software Configuration Guide.

Cisco ASR 903 Router Initial Configuration

This chapter guides you through a basic router configuration, which is sufficient for you to access your network. Complex configuration procedures are beyond the scope of this publication and can be found in the modular configuration and modular command reference publications in the Cisco IOS software configuration documentation set that corresponds to the software release installed on your Cisco hardware.

To configure the Cisco ASR 903 Router from a console, you need to connect a terminal to the router console port.

This chapter contains the following sections:

Checking Conditions Prior to System Startup, page 4-1

Powering Up the Cisco ASR 903 Router, page 4-2

Configuring the Cisco ASR 903 Router at Startup, page 4-5

Safely Powering Off the Cisco ASR 903 Router, page 4-8

Checking Conditions Prior to System Startup

Ensure that the following conditions are addressed before starting up the router:

The Route Switch Processor (RSP) is installed.

The optional Gigabit Ethernet Management port cable is installed.

The chassis is securely mounted and grounded.

The power and interface cables are connected.

Your PC with terminal emulation program (hyperTerminal or equivalent) is connected to the console port and powered up.

Your PC terminal emulation program is configured for 9600 baud, 8 data bits, 1 stop-bit,no parity, and flow control is set to none.

You have selected passwords for access control.

Captive installation screws are tight on all removable components.

The console terminal is turned on.

You have determined the IP addresses for the Ethernet and serial interfaces.

Empty card slots or card bays are filled with card blanks. This ensures proper air flow through the chassis and electromagnetic compatibility (EMC).

Powering Up the Cisco ASR 903 Router

Powering Up the Cisco ASR 903 Router

Make certain that all card slots and compartments are closed off. Install blank faceplates on any empty slots. Always have power supply slots filled. If you leave a power supply slot uncovered, then you risk exposure to hazardous voltages on the power pins on the midplane.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.Statement 1029

After installing your Cisco ASR 903 Router and connecting cables, start the router and follow these steps:

Step 1 Activate the DC power supply using the steps described in“Activating the DC Power Supply” procedure on page 3-23.

Caution Do not press any keys on the keyboard until the messages stop and the SYS PWR LED is solid green. Any keys pressed during this time are interpreted as the first command typed when the messages stop, which might cause the router to power off and start over. It takes a few minutes for the messages to stop.

Note This is only an example of what can display. The system boots differently depending upon the configuration that ships with your system.

Step 2 Observe the initialization process. When the system boot is complete (the process takes a few seconds), the Cisco ASR 903 Router RSP begins to initialize.

Router>

Step 3 From user EXEC mode, enter the enable command as shown in the following example:

Router> enable

Step 4 At the password prompt, enter your system password. If an enable password has not been set on your system, this step may be skipped. The following example shows entry of the password calledenablepass:

Password: enablepass

Step 5 When your enable password is accepted, the privileged EXEC mode prompt appears: Router#

Step 6 You now have access to the CLI in privileged EXEC mode and you can enter the necessary commands to complete your desired tasks. To exit the console session, enter the quit command as shown in the following example:

Router# quit

Configuring Global Parameters

When you first start the setup program, you must configure the global parameters. These parameters are used for controlling system-widesettings. Perform the following steps to enter the global parameters:

Step 1 Connect a console terminal to the console port, and then boot the router.

Note This is only an example of the output display; prompts may vary.

When you see this information, you have successfully booted your router:

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

At any point you may enter a question mark '?' for help.

Use ctrl-cto abort configuration dialog at any prompt.

Default settings are in square brackets '[]'.

Basic management setup configures only enough connectivity for management of the system, extended setup will ask you to configure each interface on the system.

Basic management setup configures enough connectivity for managing the system; extended setup will ask you to configure each interface on the system. For detailed information about setting global parameters, refer to the Cisco ASR 903 Router Software Configuration Guide.

Checking the Running Configuration Settings

To check the value of the settings you have entered, enter the show running-config command at the

Router# prompt:

Router# showrunning-config

To review changes you make to the configuration, use the EXEC mode show startup-config command to see the changes and copyrun-startstored in NVRAM.

Saving the Running Configuration to NVRAM

To store the configuration or changes to your startup configuration in NVRAM, enter the copy running-configstartup-configcommand at the Router# prompt:

Router# copy running-configstartup-config

Using this command saves the configuration settings that you created in the router using configuration mode and the setup facility. If you fail to do this, your configuration will be lost the next time you reload the router.
