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.

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.

Severity 1 (S1)—Yournetwork is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.

Severity 2 (S2)—Operationof an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commitfull-timeresources during normal business hours to resolve the situation.

Severity 3 (S3)—Operationalperformance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.

Severity 4 (S4)—Yourequire information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.

Interface Numbering

Interface Numbering

This section describes numbering conventions for interfaces on Cisco 3725 and Cisco 3745 routers.

Cisco 3725 Interfaces

Each individual interface (port) on a Cisco 3725 router is identified by number, as described in the following sections.

WAN and LAN Interface Numbering

The Cisco 3725 router chassis contains the following WAN and LAN interface types:

Two built-inFast Ethernet LAN interfaces

Three slots in which you can install WAN interface cards (WICs)

One single-wideslot (slot 1) in which you can install one network module

One double-wideslot (slot 2) in which you can install onesingle-wideordouble-widenetwork module

The numbering format is interface-type slot-number/interface-number.Two examples are:

FastEthernet 0/0

Serial 1/2

The slot numbers are as follows:

0 for all built-ininterfaces

0 for all WIC interfaces

1 for interfaces in the single-widenetwork module slot

2 for interfaces in the double-widenetwork module slot

Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top.

Figure 1-3 shows an example of interface numbering on a Cisco 3725 router with these interfaces:

A WIC in each WIC slot (containing interfaces Serial 0/0 and Serial 0/1 in physical slot W0, interface Serial 0/2 in physical slot W1, and interface BRI 0/0 in physical slot W2)

A 2-portT1 network module in slot 1 (containing the following ports: T1 1/0 and T1 1/1)

A 36-portEtherSwitch network module in slot 2 (containing the following ports: Fast Ethernet 2/0 through 2/35, and Gigabit Ethernet 2/0 and 2/1)

Two built-inEthernet10/100-Mbpsinterfaces—FastEthernet 0/0 and Fast Ethernet 0/1

The slot number for all WIC interfaces is always 0. (The W0 and W1 slot designations are for physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are as follows:

If slot W0 is empty and slot W1 contains a 1-portserial WIC, the serial interface in the WIC is numbered Serial 0/0.

If slot W0 contains a 2-portserial WIC and slot W1 contains a1-portserial WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the serial interface in physical slot W1 is numbered Serial 0/2.

If slot W0 contains a 2-portserial WIC and slot W1 contains a1-portBRI WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the BRI interface in physical slot W1 is numbered BRI 0/0.

Voice Interface Numbering

Voice interfaces are numbered as follows: chassis-slot/voice-module-slot/voice-interface

If a 4-channelvoice network module is installed in chassis slot 1, the voice interfaces are:

1/0/0—Chassisslot 1/Voice module slot 0/Voice interface 0

1/0/1—Chassisslot 1/Voice module slot 0/Voice interface 1

Interface Numbering

Cisco 3745 Interfaces

Each individual interface (port) on a Cisco 3745 router is identified by number as described in the following sections.

WAN and LAN Interface Numbering

The Cisco 3745 router chassis contains the following WAN and LAN interface types:

Two built-inFastEthernet LAN interfaces

Three slots in which you can install WAN or voice interface cards

Four network module slots

The numbering format is interface-type slot-number/interface-number.Two examples are:

FastEthernet 0/0

Serial 1/2

The slot numbers are as follows:

0 for all built-ininterfaces

0 for all WIC interfaces

1 for the lower-rightnetwork module slot

2 for the lower-leftnetwork module slot

3 for the upper-rightnetwork module slot

4 for the upper-leftnetwork module slot

If double-widenetwork modules are installed, the network module slots are numbered as follows:

2 for the lower double-wideslot

4 for the upper double-wideslot

Interface (port) numbers begin at 0 for each interface type, and continue from right to left and from bottom to top.

Figure 1-4 shows the rear panel of the Cisco 3745 with:

A WIC in each of the three WAN interface card slots

A single-widenetwork module in each of the four network module slots

Two AC power supplies

The slot number for all WIC interfaces is always 0. (The W0, W1, and W2 slot designations are for physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are:

If physical slot W0 is empty and physical slot W1 contains a 1-portserial WIC, the serial interface in the WIC is numbered Serial 0/0.

If slot W0 contains a 2-portserial WIC and slot W1 contains a1-portserial WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the serial interface in physical slot W1 is numbered Serial 0/2.

If slot W0 contains a 2-portserial WIC and slot W1 contains a1-portBRI WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the BRI interface in physical slot W1 is numbered BRI 0/0.

Chapter 2 Preparing to Install the Router

Safety Recommendations

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

Warning Read the installation instructions before connecting the system to the power source.Statement 1004

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

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

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

Do not work alone if hazardous conditions exist.

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

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn off power to the device.

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

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

In addition, use the following guidelines 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 it.

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

Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

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

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

Wear an ESD-preventivewrist strap, ensuring that it makes good skin contact. Connect the clip to an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. 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.

OL-2180-07

 

 

Chapter 2 Preparing to Install the Router

General Site Requirements

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

General Site Requirements

This section describes the requirements your site must meet for safe installation and operation of your router. Ensure that the site is properly prepared before beginning installation. If you are experiencing shutdowns or unusually high errors with your existing equipment, this section can also help you isolate the cause of failures and prevent future problems.

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 The device is designed for connection to TN and IT power systems.Statement 1007

The AC power supply includes the following features:

It autoselects either 110 V or 220 V operation.

All units include a 6-foot(1.8-meter)electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)

Chapter 2 Preparing to Install the Router

General Site Requirements

Site Environment

Cisco 3700 series routers can be placed on a desktop or installed in a rack. The location of your router and the layout of your equipment rack or wiring room are extremely important considerations for proper operation. Equipment placed too close together, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for access to both front and rear panels of the router.

When planning your site layout and equipment locations, remember the precautions described in the next section, “Site Configuration,” to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Site Configuration

The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:

Ensure that the room where your router operates has adequate circulation. Electrical equipment generates heat. Without adequate circulation, ambient air temperature may not cool equipment to acceptable operating temperatures.

Always follow ESD-preventionprocedures described in the“Preventing Electrostatic Discharge Damage” section on page 2-2 to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Ensure that the chassis cover or mainboard tray and module rear panels are secure. All empty network module slots, interface card slots, and power supply bays must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings will create air leaks, which may interrupt and reduce the flow of air across internal components.

Equipment Racks

Cisco 3700 series routers include brackets for use with a 19-inchrack or, if specified in your order, optional larger brackets for use with a23-inchrack.

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

Allow clearance around the rack for maintenance.

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 generated by 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 intake ports or exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated into the rack.

Cisco 3700 Series Routers Hardware Installation Guide

2-4

OL-2180-07

 

 

Chapter 2 Preparing to Install the Router

Installation Checklist

Baffles can help to 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 down other equipment in the rack (and in adjacent racks) to allow the router being tested a maximum of cooling air and clean power.

Installation Checklist

The sample installation checklist lists items and procedures for installing a new router. Make a copy of this checklist and mark the entries when completed. Include a copy of the checklist for each router in your site log (described in the next section, “Creating a Site Log”).

Creating a Site Log

Creating a Site Log

The site log provides a record of all actions related to the router. Keep it in an accessible place near the chassis where anyone who performs tasks has access to it. Use the installation checklist to verify steps in the installation and maintenance of the router. Site Log entries might include the following information:

Installation progress—Makea copy of the installation checklist and insert it into the site log. Make entries as each procedure is completed.

Upgrade and maintenance procedures—Usethe site log as a record of ongoing router maintenance and expansion history. A site log might include the following events:

Installation of network modules

Removal or replacement of network modules and other upgrades

Configuration changes

Maintenance schedules and requirements

Maintenance procedures performed

Intermittent problems

Comments and notes

Inspecting the Router

Do not unpack the router until you are ready to install it. If the final installation site will not be ready for some time, keep the chassis in its shipping container to prevent accidental damage. When you are ready to install the router, proceed with unpacking it.

The router, cables, publications, and any optional equipment you ordered may be shipped in more than one container. When you unpack the containers, check the packing list to ensure that you received all the following items:

Router

6-foot(1.8-meter)power cord

Rack-mountbrackets

Ground lug

Cable guides (for Cisco 3725 routers)

RJ-45-to-DB-9adapter cable

Chapter 2 Preparing to Install the Router

Console and Auxiliary Port Considerations

Console and Auxiliary Port Considerations

The router includes an asynchronous serial console port and an auxiliary port. The console and auxiliary ports provide access to the router either locally using a console terminal connected to the console port, or remotely using a modem connected to the auxiliary port. This section discusses important cabling information to consider before connecting the router to a console terminal or modem.

The main difference between the console and auxiliary ports is that the auxiliary port supports hardware flow control and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures 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 send data at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

Console Port Connections

The router has an EIA/TIA-232asynchronous serial console port(RJ-45).Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable.

For connection to a PC running terminal emulation software, your router is provided with an RJ-45toDB-9adapter cable.

To connect the router to an ASCII terminal, use an RJ-45rollover cable and anRJ-45-to-DB-25female adapter (not provided).

The default parameters for the console port are 9600 bps, 8 data bits, no parity, and 2 stop bits. The console port does not support hardware flow control. For detailed information about installing a console terminal, see the “Connecting to a Console Terminal or Modem” section on page 3-22.

For cable and port pinouts, see the document Cisco Modular Access Router Cable Specifications on Cisco.com.

Auxiliary Port Connections

The router has an EIA/TIA-232asynchronous serial auxiliary port(RJ-45)that supports flow control. Depending on the cable and the adapter used, this port will appear as a DTE or DCE device at the end of the cable.

For connection to a modem, your router is provided with an RJ-45-to-DB-25adapter cable.

For detailed information about connecting devices to the auxiliary port, see the “Connecting to a Console Terminal or Modem” section on page 3-22.

For cable and port pinouts, see the document Cisco Modular Access Router Cable Specifications on Cisco.com.

Cisco Modular Access Router Cable Specifications

Warning To avoid electric shock, do not connect safetyextra-lowvoltage (SELV) circuits totelephone-networkvoltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both useRJ-45connectors.Statement 1021

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet implementations are as follows:

100BASE-T—2-pairCategory 5 or unshieldedtwisted-pair(UTP)straight-throughRJ-45cable.

10BASE-2—Etherneton thin coaxial cable, also known asthin Ethernet. The maximum segment distance is 607 feet (186 meters).

10BASE-5—Etherneton thick coaxial cable, also known asthick Ethernet. The maximum segment distance is 1,640 feet (500 meters).

10BASE-T—Etherneton unshieldedtwisted-pair(UTP) cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not meet.

Chapter 2 Preparing to Install the Router

Preparing to Connect to a Network

Token Ring Connections

The IEEE has established Token Ring as standard IEEE 802.5. Specifications indicate a maximum segment distance of 328 feet (100 meters) for UTP cabling.

Note To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make sure that you use a shieldedRJ-45Token Ring cable when connecting your router to a Token Ring network.

Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the Token Ring must use the same operating speed.

Use a Token Ring cable to connect the router to a switch. See the section “Token Ring Port Pinouts” in the Cisco Modular Access Router Cable Specifications document for Token Ring port pinouts. This document is available on Cisco.com.

Serial Connections

Serial connections are provided by WAN interface cards and network modules. For more information on WAN interface cards, see the Cisco Interface Cards Installation Guide. For more information on network modules, see theCisco Network Modules Hardware Installation Guide. These documents are available on Cisco.com.

Before you connect a device to a serial port, you need to know the following:

Type of device—dataterminal equipment (DTE) or data communications equipment(DCE)—thatyou are connecting to the synchronous serial interface

Type of connector—maleorfemale—requiredto connect to the device

Signaling standard required by the device

Configuring Serial Connections

The serial ports on the asynchronous/synchronous serial network modules and the serial WAN interface card use DB-60connectors. Serial ports can be configured as DTE or DCE, depending on the serial cable used.

Serial DTE or DCE Devices

A device that communicates over a synchronous serial interface is either a DTE or a DCE device. A DCE device provides a clock signal that paces the communications between the device and the router. A DTE device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a jumper to select either DTE or DCE mode.) Table 2-2 lists typical DTW and DCE devices.

1.If pins protrude from the base of the connector, the connector is male.

2.If the connector has holes to accept pins, the connector is female.

Signaling Standards Supported

The synchronous serial ports available for the router support the following signaling standards: EIA/TIA-232,EIA/TIA-449,V.35, X.21, andEIA-530.You can order a CiscoDB-60shielded serial transition cable that has the appropriate connector for the standard you specify. The documentation for the device you want to connect should indicate the standard used for that device. The router end of the shielded serial transition cable has aDB-60connector, which connects to theDB-60port on a serial WAN interface card. The other end of the serial transition cable is available with a connector appropriate for the standard you specify.

The synchronous serial port can be configured as DTE or DCE, depending on the attached cable (except EIA-530,which is DTE only). To order a shielded cable, contact customer service. See the“Obtaining Technical Assistance” section on page xvii.

Note All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device.

Although manufacturing your own serial cables is not recommended (because of the small size of the pins on the DB-60serial connector), cable pinouts are provided in theCisco Modular Access Router Cable Specifications document.

Distance Limitations

Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the greater the distance. All serial signals are subject to distance limits, beyond which a signal significantly degrades or is completely lost.

Note Only the serial WAN interface card supports bit rates above 128 kbps.

Table 2-3 lists the recommended maximum speeds and distances for each serial interface type. However, you might get good results at speeds and distances greater than those listed if you understand the electrical problems that might arise and can compensate for them. For instance, the recommended maximum rate for V.35 is 2 Mbps, but 4 Mbps is commonly used.

Asynchronous/Synchronous Serial Module Data Rates

The following data-ratelimitations apply to theslow-speedserial interfaces found in the asynchronous/synchronous serial modules:

Asynchronous interface—Maximumdata rate is 115.2 kbps.

Synchronous interface—Maximumdata rate is128-kbpsfull duplex.

ISDN BRI Connections

The BRI WAN interface cards provide Integrated Services Digital Network (ISDN) Basic Rate Interface (BRI) connections. The BRI modules and BRI WAN interface cards are available with either an S/T interface that requires an external Network Termination 1 (NT1), or a U interface that has a built-inNT1.

You can install the BRI modules in any available slot in the chassis.

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

Use a BRI cable (not included) to connect the BRI WAN interface card directly to an ISDN. Table 2-4 lists the specifications for ISDN BRI cables. See theCisco Modular Access Router Cable Specifications online document for pinouts. This document is available on Cisco.com.

Note If modules, interface cards, or power supplies need to be removed or installed, Cisco suggests that you perform the installation or removal before you install the chassis. If a chassis cover needs to be removed, the chassis may have to be removed from the rack to permit cover removal.

Note The Cisco 3745 accommodates two AC or two DChot-swappablepower supplies in bays at the rear of the unit. Each unit provides up to 230 W of power, and a single installed power supply meets the router’s requirements. The second installed power supply provides redundancy, load sharing, and increased system availability. Either power supply can be removed without affecting system operation.

If the required network modules, interface cards, and power supplies are already installed, proceed to the “Setting Up the Chassis” section on page 3-2.

Setting Up the Chassis

You can set the chassis on a desktop or install it in a rack. Select the procedure that best meets the needs of your network. These procedures are described in the following sections:

Chapter 3 Installing the Router

Setting Up 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.Statement 1032

Caution Do not place anything on top of the router that weighs more than 10 lb (4.5 kg). Excessive weight on top could damage the chassis.

After the router has been installed, you must connect the chassis to a reliable earth ground. For the chassis ground connection procedures, see the “Installing the Chassis Ground Connection” section on page 3-8.

Rack-Mountingthe Chassis

If you are planning to rack-mountthe router, do so before making network and power connections. If you need to install network modules or interface cards, you can do so either before or afterrack-mountingthe router. Ideally, you would install modules and interface cards when you have the best access to the rear panel of the router.

Note The Cisco 3725 requires additional clearance on the left side (as viewed from the front of the chassis) to accommodate cooling fans. This clearance is provided through the use of special brackets. Be sure to install the wide bracket (marked right) on the side of the chassis with the cooling fans.

The Cisco 3725 router is shipped with rack-mountingbrackets for19-inchracks. (SeeFigure 3-1.)

Installing the Chassis Ground Connection

For NEC-compliantgrounding, use size AWG 14 (2 mm2) or larger wire and an appropriateuser-suppliedring terminal.

For EN/IEC 60950-compliantgrounding, use size AWG 18 (1 mm2) or larger wire and an appropriateuser-suppliedring terminal.

For chassis grounding instruction, see one of the following sections:

Cisco 3725 Router Ground Connection, page 3-9

Cisco 3745 Router Ground Connection, page 3-10

Cisco 3725 Router Ground Connection

To install the ground connection for a Cisco 3725 router, perform the following steps:

Step 1 Strip one end of the ground wire to the length required for the ground lug or terminal.

For the NEBS ground lug—approximately0.75 inch (20 mm)

For user-providedringterminal—asrequired

Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.

Step 3 Attach the ground lug or ring terminal to the chassis as shown inFigure 3-12 orFigure 3-13.For a ground lug, use the two screws with captive locking washers provided. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10in-lb(0.9 to 1.1N-m).

Step 4 Connect the other end of the ground wire to a grounding point at your site.

If your router uses AC power, connect it to a 15 A, 120 VAC (10 A, 240 VAC) circuit with overcurrent protection.

Note The input voltage tolerance limits for AC power are 85 and 264 VAC.

Warning AC connected units must have a permanent ground connection in addition to the power cable ground wire.NEBS-compliantgrounding satisfies this requirement.Statement 284

Warning This product relies on the building’s installation forshort-circuit(overcurrent) protection. Ensure that the protective device is rated not greater than:

15A, 120VAC (10A, 240VAC). Statement 1005

Caution To comply with Telcordia NEBSGR-1089-Coreand EN 300386 requirements, you must use foiltwisted-paircable that is properly grounded at both ends.

Connecting Routers to a DC-InputPower Supply

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

Statement 1003

Warning Use copper conductors only.Statement 1025

Note The installation must comply with the 1996 National Electric Code (NEC) and other applicable codes.

If your router has a DC-inputpower supply, follow the directions in this section for proper wiring. A router with aDC-inputpower supply has a terminal block for the DC power connections.

Depending on the type of router you are installing, see one of the following procedures:

Wiring Procedure for Cisco 3725 Routers

To connect a Cisco 3725 router to a DC power source, perform the following steps:

Step 1 Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the circuit breaker for the DC circuit, switch the circuit breaker to the OFF position, and tape thecircuit-breakerswitch in the OFF position.

Tip Secure all power cabling when installing this unit to avoid disturbingfield-wiringconnections.

Step 2 Strip the wires to the appropriate length for the terminals. The strip length is 1/8 to 3/16 inch (3 to 5 mm) for Molex number19193-0009and for AMP number324159-0terminals.

Step 3 Crimp the terminals to the power input and safety ground wires.

Warning When stranded wiring is required, use approved wiring terminations, such asclosed-looporspade-typewith upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.Statement 1002

Step 4 Remove the plastic cover from the terminal block. Save it for reinstallation after you finish wiring.

Step 5 Connect the DC power input wires to the terminal block as shown inFigure 3-16.To avoid interference with the on/off switch, organize the wires downward from the terminal block.

Power Connections

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always be connected first and disconnected last.Statement 239

Caution Do not overtorque the terminal block contact screws. Recommended torque is 8.0 ± 0.5in-lb(0.9 ± 0.05N-m).

Approved Scenarios and Scenarios Not Approved for Dual DC Power Supply Configuration in Cisco 3725 Routers

You can connect a single DC power source to either the A input or the B input. If there are dual power sources, connect one source to the A input and one source to the B input. Both sources must be the same polarity (with respect to ground) and voltage (within 0.25 volts). Do not connect –DCgrounded and +DC grounded dual sources to a Cisco 3725 router.

Caution Dual sources withopposite-polaritygrounding can damage equipment.

In Figure 3-18,either the positive source terminal or the negative source terminal is tied to ground.

In Figure 3-20,source A and source B share common positive terminal connections. This is allowed only if Va equals Vb (within 0.25 V).

Caution When connecting source A and source B with common positive terminals, if source A and source B voltages are unequal by more than 0.25 V, thehigher-voltagesource can discharge into thelower-voltagesource through the A- and B- input terminals. Excessive discharging currents through these terminals can cause one or both of the dual input DC power supply's internal A- or B- fuses to open, resulting in lack of redundancy or system failure. When source A and source B are within 0.25 V, discharge current is minimal.

Note When source A and source B are wired with common negative terminals, as inFigure 3-19,discharging does not occur and there is no restriction requiring that source A and source B voltages be equal.

Wiring Procedure for DC Input

To connect the router to a DC power source, perform the following steps:

Step 1 Remove power from the DC circuit. To ensure that power is removed from the DC circuit, locate the circuit breaker for the DC circuit, switch the circuit breaker to the OFF position, and tape thecircuit-breakerswitch in the OFF position.

Tip Secure all power cabling when installing this unit to avoid disturbingfield-wiringconnections.

Step 2 Strip the wires to the appropriate length for the terminals. The strip length is 1/8 to 3/16 inch (3 to 5 mm) for Molex number19073-0009terminals and for AMP/Tyco number 52961 terminals.

Step 3 Crimp the terminals onto the DC power input wires.

Power Connections

Warning When stranded wiring is required, use approved wiring terminations, such asclosed-looporspade-typewith upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.Statement 1002

Step 4 Remove the plastic cover from the terminal block. Save it for reinstallation after you finish wiring.

Step 5 Connect the DC power input wires to the terminal block as shown inFigure 3-22 orFigure 3-23.

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always be connected first and disconnected last.Statement 239

Caution Do not overtorque the terminal block screws. The recommended torque is 8.0 ± 0.5in-lb(0.9 ± 0.05N-m).

Chapter 3 Installing the Router

Connecting to a Console Terminal or Modem

Install cable ties in accordance with site requirements.

For cable pinouts, see the online document Cisco Modular Access Router Cable Specifications.

Connecting to a Console Terminal or Modem

Your router has asynchronous serial console and auxiliary ports. These ports provide administrative access to your router either locally (with a console terminal or PC) or remotely (with a modem).

Cisco provides the following cables and adapters for connecting your router to a console terminal, PC, or modem:

One console adapter cable (RJ-45-to-DB-9,blue)

One modem adapter cable (RJ-45-to-DB-25,black)

This section describes how to connect a console terminal or PC to the console port, and how to connect a modem to the auxiliary port.

Note For information on identifying rollover cables, see the“Identifying a Rollover Cable” section on page 3-25.

Connecting to the Console Port

To connect a console terminal or a PC running terminal emulation software to the console port on the router, perform the following steps:

Step 1 Use the blueRJ-45-to-DB-9console adapter cable to connect the router to a terminal. (SeeFigure 3-24 andFigure 3-25.)

For information about cable pinouts, see the online publication Cisco Modular Access Router Cable Specifications, available online and on the DocumentationCD-ROM.

Note On Cisco routers, the console port iscolor-codedblue.

Step 2 Configure your terminal or terminal emulation software for 9600 baud (default), 8 data bits, no parity, and 2 stop bits.

Note Because hardware flow control is not possible on the console port, we do not recommend that modems be connected to the console port. Modems should always be connected to the auxiliary port.

Identifying a Rollover Cable

Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify a rollover cable by comparing the two modular ends of the cable. Holding the cables side by side, with the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color as the wire connected to the pin on the outside of the right plug. (See Figure 3-28.)If your cable came from Cisco, pin 1 will be white on one connector, and pin 8 will be white on the other (a rollover cable reverses pins 1 and 8, 2 and 7, 3 and 6, and 4 and 5).

Chapter 3 Installing the Router

Configuring the Router

 

 

 

 

 

 

The setup command facility prompts you for basic information about your router and network, and it

 

 

 

 

 

 

creates an initial configuration file.The prompts vary, depending on your router model, the installed

 

 

 

 

 

 

interface modules, and the software image. The following example and the user entries (in bold) are

 

 

 

 

 

 

shown as examples only.

 

 

 

 

 

 

For a description of the interface numbering, see the “Interface Numbering” section on page 1-5.

 

 

 

 

 

 

 

 

 

 

Note

If you make a mistake while using the setup command facility, you can exit and run the setup command

 

 

 

 

 

 

facility again. Press Ctrl-C,and entersetup at the privileged EXEC mode prompt (Router#).

 

 

 

 

 

 

 

 

 

 

 

 

 

Step 1

To proceed using the setup command facility, enter yes when thepower-upmessages have ended.

 

 

 

 

 

 

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

 

 

 

Step 2

When the following messages appear, press Return to enter basic management setup:

 

 

 

 

 

 

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

 

 

 

 

 

 

Would you like to enter basic management setup? [yes/no]: yes

 

 

 

Step 3

Enter a host name for the router (this example uses 3700):

 

 

 

 

 

 

Configuring global parameters:

 

 

 

 

 

 

Enter host name [Router]: 3700

 

 

 

Step 4

Enter an enable secret password. This password is encrypted (more secure) and cannot be seen when you

 

 

 

 

 

 

view the configuration:

 

 

 

 

 

 

The enable secret is a password used to protect access to

 

 

 

 

 

 

privileged EXEC and configuration modes. This password, after

 

 

 

 

 

 

entered, becomes encrypted in the configuration.

 

 

 

 

 

 

Enter enable secret: xxxxxx

 

 

 

Step 5

Enter an enable password that is different from the enable secret password. This password is not

 

 

 

 

 

 

encrypted (less secure) and can be seen when you view the configuration:

 

 

 

 

 

 

The enable password is used when you do not specify an

 

 

 

 

 

 

enable secret password, with some older software versions, and

 

 

 

 

 

 

some boot images.

 

 

 

 

 

 

Enter enable password: xxxxxx

 

 

 

Step 6

Enter the virtual terminal password, which prevents unauthenticated access to the router through ports

 

 

 

 

 

 

other than the console port:

 

 

 

 

 

 

The virtual terminal password is used to protect

 

 

 

 

 

 

access to the router over a network interface.

 

 

 

 

 

 

Enter virtual terminal password: xxxxxx

 

 

 

Step 7

Respond to the following prompts as appropriate for your network:

 

 

 

 

 

 

Configure SNMP Network Management? [yes]:

Appendix A Troubleshooting

Solving Problems

Solving Problems

The key to solving problems is to isolate the problem to a specific subsystem by comparing what the router is doing to what it should be doing.

The LEDs on the front and rear panel of the router enable you to determine router performance and operation. LEDs are described in the following sections:

Reading Front-Panel LEDs, page A-4

Reading Rear Panel LEDs, page A-6

When solving problems, consider the following router subsystems:

Power and cooling systems—Externalpower source, power cable, router power supply and circuit breaker, and router blower and fan. Also consider inadequate ventilation or air circulation.

Modules—LEDson the modules help identify a failure.

Cables—Externalcables that connect the router to the network.

Troubleshooting the Power and Cooling Systems

Both the system LED and the fans can help you troubleshoot a power problem. Check the following items to help isolate the problem:

With the power switch on, does the system LED stay on or blink?

If the LED is green, the router is receiving power and is functional.

If the LED is amber, the router is receiving power but is not functional.

If the LED is off, check the power source and power cable.

With the power switch on and the system LED on, do the fans operate?

If no, check the fans.

With the power switch on and the system LED off, do the fans operate?

If yes, the router is receiving power. The fans are connected directly to the DC outputs of the power supply.

If no, check the power source and power cable.

Does the router shut down after being on for a short time?

Check for an environmentally induced shutdown. See the next section, “Environmental Reporting Features.”

Check the environmental site requirements in the “General Site Requirements” section on page 2-3.

Check for a power supply failure by inspecting the system and power supply LEDs on the front panel. If they are green, the power supplies are functional.

Cisco 3700 Series Routers Hardware Installation Guide

 

A-2

OL-2180-08

 

 

 

Appendix A Troubleshooting

Solving Problems

Router partially boots, but LEDs do not go on.

Check for a power supply failure by inspecting the system LED on the front panel of the router. If the system LED is on, the power supply is functional.

If the system LED is not on, see the “Obtaining Technical Assistance” section on page xvii for information about customer service.

Check for a power supply failure by inspecting the power supply LEDs on the front panel. See the “Reading Front-Panel LEDs” section on page A-4 for power supply LED descriptions.

Environmental Reporting Features

If the router is operating at an abnormally high temperature, the following message is displayed on the console screen:

%SYS-1-OVERTEMP:System detected OVERTEMPERATURE condition. Please resolve cooling

problem immediately!

Some causes of abnormally high router temperature are as follows:

Fan failure

Air conditioner failure in the room

Air blockage to cooling vents

Take steps to correct the problem. See also the “Site Environment” section on page 2-4 and the“Equipment Racks” section on page 2-4.

Troubleshooting Modules, Cables, and Connections

Network problems can be caused by a module; cables or cable connections; or external devices such as a modem, transceiver, hub, wall jack, WAN interface, or terminal. Check for the following symptoms to help isolate the problem:

Module is not recognized by the router.

Make sure that the module is firmly seated in its slot.

Check the LEDs on the module. Each module has its own set of LEDs. For information on these LEDs, see the online Cisco Network Modules Hardware Installation Guide.

Make sure you have a version of Cisco IOS software that supports the module. Check the online

Software Configuration Guide for Cisco 2600, Cisco 3600, and Cisco 3700 Series Routers or accompanying configuration note for software requirements for the network module.

Module is recognized, but interface ports do not initialize.

Make sure that the module is firmly seated in its slot.

Check external cable connections.

Make sure that you have a version of Cisco IOS software that supports the network module and interface card. Check the Cisco Network Modules Hardware Installation Guide and the

Cisco Interface Cards Hardware Installation Guide or accompanying configuration notes for the affected network module and interface card software requirements.

Router does not boot properly, or constantly or intermittently reboots.

Make sure that all modules are firmly seated in their slots.

Check the router chassis or software. See the “Obtaining Technical Assistance” section on page xvii for information about customer service.

Router boots, but the console screen is frozen.

Check the external console connection.

Verify that the parameters for your terminal are set as follows:

(a)The same data rate as configured for the router (9600 baud is the default)

(b)8 data bits

(c)No parity generated or checked

(d)2 stop bits

Router powers on and boots only when a particular module is removed.

Check the module. See the “Obtaining Technical Assistance” section on page xvii for information about customer service.

Router powers on and boots only when a particular cable is disconnected.

There may be a problem with the module or cable. See the “Obtaining Technical Assistance” section on page xvii for information about customer service.

Reading Front-PanelLEDs

The LEDs on the front panel of the router enable you to determine router performance and operation. Figure A-1 andFigure A-2 show the LEDs on the front panel of the router. For an explanation of these LEDs seeTable A-1 andTable A-2.

Error Messages

Cisco IOS software displays system error and recovery messages on an external device console terminal screen. (For more information, see the “Connecting to a Console Terminal or Modem” section on page 3-22.)

The terminal should display one of the following prompts:

Router> (indicates the user EXEC command mode)

or

Router# (indicates the privileged EXEC command mode)

The Cisco IOS software checks the system condition once every 30 seconds. If the condition still exists, the error message appears again; if the error condition has cleared, a recovery message appears.

Table A-5 describes system error and recovery messages and LED conditions that might accompany them.

Note Table A-5 does not provide a complete list of system LED conditions. (For all LED conditions that can occur in your router, see the“Reading Front-Panel LEDs” section on page A-4 and the“Reading Rear Panel LEDs” section on page A-6.)

Using the ROM Monitor

This appendix describes the ROM monitor (also called the bootstrap program), the firmware that runs when your Cisco 3700 series router is powered up or reset. During normal operation, the ROM monitor helps to initialize the processor hardware and boot the operating system software. You can also use the ROM monitor to isolate or eliminate hardware problems and recover a corrupted Cisco IOS software image.

This appendix includes the following sections:

Entering ROM Monitor Mode, page B-1

ROM Monitor Commands, page B-2

ROM Monitor Syntax Conventions, page B-3

ROM Monitor Command Descriptions, page B-3

Recovering Cisco IOS Software Images, page B-8

Entering ROM Monitor Mode

To use the ROM monitor, you must have access to the console port. See the “Connecting to a Console Terminal or Modem” section on page 3-22 for information on connecting the console cable.

There are two ways of entering the ROM monitor mode:

Use the reload command and the Break key to enter the ROM monitor mode forone-timeuse.

Break (system interrupt) is always enabled for 60 seconds after the router reboots, regardless of whether Break is configured on or off in the configuration register (see Appendix C, “Configuration Register”). During this60-secondperiod, you can break to the ROM monitor prompt by pressing the Break key.

Note If your console terminal does not have a Break key, see the terminal emulator documentation for instructions on generating a break (system interrupt).

Set the configuration register so that the router enters the ROM monitor mode whenever it boots.

The new configuration register value, 0x0, is effective after the router is rebooted with the reload command. The router remains in the ROM monitor and does not boot the operating system.

As long as the configuration register value remains 0x0, you must manually boot the operating system from the console. See the boot command in the“ROM Monitor Command Descriptions” section on page B-3.

Cisco 3700 Series Routers Hardware Installation Guide

 

OL-2180-08

Appendix B Using the ROM Monitor

ROM Monitor Commands

The two methods of entering the ROM monitor mode are as follows.

Enter ROM Monitor Mode by Using the reload Command

Connect to the router from a console, and follow these steps:

Step 1 Restart the router with thereload command.

Router# reload

Step 2 Press theBreak key during the first 60 seconds of the system booting.

This forces the router into ROM monitor mode, and the ROM monitor prompt appears:

rommon 1>

Enter ROM Monitor Mode by Resetting the Configuration Register

Connect to the router from a console, and follow these steps:

Step 1 Set the bits 3, 2, 1, and 0 of the configuration register to zero.

Router# configuration-register0x0

Step 2 Restart the router with thereload command.

Router# reload

The router boots into ROM monitor mode, and the ROM monitor prompt is displayed:

rommon 1>

Note The number that appears in the ROM monitor prompt (1>, 2>, and so forth) is the line number. It increments each time you enter a ROM monitor command.

ROM Monitor Syntax Conventions

ROM monitor syntax in this appendix uses the following conventions:

Square brackets [ ] denote an optional element. In the following example, the element abc is not required, but you can specify it if you choose:

command [abc]

If a minus option is followed by a colon (for example, [-s:])you must provide an argument for the option.

A term in italics means that you must fill in the appropriate information. In the following example, you replace the term in italics with the interface type you are using:

command interface-type

ROM Monitor Command Descriptions

This section describes some useful ROM monitor commands. See the Cisco IOS configuration guides and command references for more information on ROM monitor commands.

Boot Commands in the ROM Monitor

The router always boots first from a Cisco IOS software image in CompactFlash memory, because there is no separate, dedicated boot helper image ([rx]boot). The first image in CompactFlash memory functions as the boot helper image, but you can override this by setting the BOOTLDR Monitor

Cisco 3700 Series Routers Hardware Installation Guide

 

OL-2180-08

B-3

 

Appendix B Using the ROM Monitor

ROM Monitor Command Descriptions

environment variable to point to another image. The first image in CompactFlash memory is invoked if the ROM monitor does not recognize a device ID specified in the boot command. The router cannot boot if there is no Cisco IOS software image in CompactFlash memory.

To boot a router from a Cisco IOS software image on a TFTP server (netboot), the installed DRAM must be adequate to hold two uncompressed Cisco IOS software images: the image from CompactFlash memory and the image downloaded from the TFTP server.

If the router is configured to boot from a TFTP server (boot bits in the configuration register are set from 2 to 15), the router first boots from the image in CompactFlash memory. It decompresses that image in DRAM, parses the boot system commands, downloads the Cisco IOS software image from the TFTP server, and decompresses it in DRAM. After the Cisco IOS software image from the TFTP server is in DRAM, the DRAM memory occupied by the boot helper image is released.

Note Booting from a TFTP server is useful if the router does not have enough CompactFlash memory to hold large images. With a small image in CompactFlash memory (just large enough to support the necessary interfaces), the router boots from CompactFlash, and then the larger image is downloaded from the TFTP server.

The boot command syntax is as follows, where:

partition is a partition number in CompactFlash memory

filename is the Cisco IOS software image file name

tftpserver is the IP address of the TFTP server

-x directs the router to load the image but not execute the boot process

-v (Verbose) specifies that progress print setting messages and error information be displayed

boot [flash: [partition: [filename]] | slot0: [partition: [filename]] | slot1: [partition: [filename]] | filename tftpserver] [-x] [-v]

Some examples of boot commands are as follows:

Note In allboot commands,boot can be entered asb.

boot—Bootsfrom the first Cisco IOS software image in internal CompactFlash memory.

boot flash:—Bootsfrom the first Cisco IOS software image in internal CompactFlash memory.

boot flash: partition:—Bootsfrom the first Cisco IOS software image in the specified partition in internal CompactFlash memory.

boot flash: filename—Bootsfrom the specified IOS software image in internal CompactFlash memory.

boot flash: partition: filename—Bootsfrom the specified Cisco IOS software image in the specified partition in internal CompactFlash memory.

boot slot0:—Bootsfrom the first Cisco IOS software image in the first partition in the CompactFlash memory card in slot 0.

boot slot0:2:—Bootsfrom the first Cisco IOS software image in the second partition in the CompactFlash memory card in slot 0.

boot slot0: filename— Boots from the specified Cisco IOS software image in the CompactFlash memory card in slot 0.

Debugging Commands in the ROM Monitor

Most debugging commands are functional only when Cisco IOS software has crashed or failed to initialize (boot). Debugging commands should normally be entered only under the direction of a Cisco engineer. If you enter a debugging command and Cisco IOS crash information is not available, the following error message appears:

“xxx: kernel context state is invalid, cannot proceed.”

The following ROM monitor debugging commands provide information about software failures:

stack ork—Producesa stack trace.

Configuration Register

The configuration register resides in NVRAM. You can view or modify the configuration register from either the ROM monitor or the operating system software.

For procedures used to change the configuration register from the operating system, and for information about configuration register settings, see Appendix C, “Configuration Register.”

To modify the configuration register from the ROM monitor, use one of these methods:

Enter the confreg command by itself for menu mode. See the“Modifying the Configuration Register in Menu Mode” section below.

Enter the confreg command plus the new hexadecimal value of the configuration register. See the next section, “Modifying the Configuration Register by Hexadecimal Entry.”

Appendix B Using the ROM Monitor

Recovering Cisco IOS Software Images

Recovering Cisco IOS Software Images

If both the boot and system images have been erased and only the ROM monitor is available, you can use the ROM monitor xmodem command to copy a Cisco IOS software image to CompactFlash memory from the console. The console can be connected directly to the router through the console port, or remotely through a modem connected to the auxiliary port.

Note Copying a Cisco IOS software image from the console is very slow. This procedure should be used only in an emergency and is not recommended for normal Cisco IOS software image upgrades.

For the fastest possible download from a console, set the console speed to 115200 bps by using the ROM monitor confreg command. See the“Configuration Register” procedure on page B-6.

Note Using a CompactFlash memory card to update the Cisco IOS software image is much faster than using the console port and, when available, is the recommended method of recovering a software image.

Description and Options of the xmodem Command

The xmodem command establishes a connection between a console and the router console port for disaster recovery, if both the boot and system images are erased from CompactFlash memory.

xmodem [filename]—Establishesan Xmodem connection between the console and the router. The optional argumentfilename specifies the source file containing the Cisco IOS software image.

Other options include the following:

c—Usescyclic redundancy check(CRC-16).

y—UsesYmodem transfer protocol.

r—Copiesthe image to dynamicrandom-accessmemory (DRAM) for launch.

x—Doesnot launch image on completion of download.

Console Requirements

The console must have the following files to use this procedure:

Terminal emulation application program supporting one of the following file transfer protocols:

Xmodem

Xmodem–CRC

Xmodem–1K

Ymodem

Procedure for the xmodem Command

To copy the Cisco IOS software image from a console to CompactFlash memory, perform the following steps:

Step 1 Connect the console using the instructions in the “Connecting to a Console Terminal or Modem” section on page 3-22.

Step 2 Power up the router. Thepower-onself-testdiagnostics run, and the boot ROM searches for a valid boot image and Cisco IOS software image in CompactFlash memory. If the boot image and Cisco IOS software image are not found, the ROM monitor prompt appears:

rommon 1>

Step 3 Enter thexmodem command and the name of the source file containing the Cisco IOS software image:

rommon 1> xmodem filename

Step 4 Messages similar to the following appear:

Do not start upload program yet...

Changing Configuration Register Settings

You might want to modify the value in the configuration register to perform the following tasks:

Recover a lost password.

Change the console data rate.

Enable or disable the Break function.

Manually boot the operating system using the b command at the ROM monitor prompt.

Force the router to automatically boot its system image in CompactFlash memory, or boot in accordance with any boot system commands stored in the router’s configuration file in NVRAM.

You can change the configuration register either from the ROM monitor or from the operating system software. To change the configuration register from the ROM monitor, see the “Configuration Register” section on page B-6.To change the configuration register from the system software, perform the following steps:

Step 1 Connect a console terminal to the console port of the router as described in the“Connecting to the Console Port” section on page 3-22,using the blueRJ-45toDB-9console adapter cable.

Note If you have a terminal with aDB-25port, use anRJ-45rollover cable andDB-25adapter. TheRJ-45-to-DB-25adapter (Cisco part number29-0810-01)can be purchased from Cisco.

For information about cable pinouts, see the publication Cisco Modular Access Router Cable

Specifications on Cisco.com.

Step 2 Configure your terminal or terminal emulation software for 9600 bps (default), 8 data bits, no parity, and 2 stop bits.

Step 3 Power up the router.

Step 4 When asked if you would like to enter the initial dialog, answerno:

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

Your router is now in the normal operating mode.

Configuring the Boot Field

Step 5 After a few seconds, you see the user EXEC prompt (Router>). Enter theenable command and your password to enter privileged EXEC mode:

Router> enable

Password: password

Router#

Step 6 At the privileged EXEC prompt (Router#), enter theconfigure terminal command:

Router# configure terminal

Enter configuration commands, one per line.

Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z

Step 7 Enter theconfig-register value command, wherevalue is a hexadecimal number preceded by0x (seeTable C-2),to set the contents of the configuration register:

Router(config)# config-register0xvalue

Note Cisco IOS software does not allow you to change the console speed bits directly with theconfig-register command. To change the console speed, complete this sequence:

Router# configure terminal

Router(config)# line console 0

Router(config-line)#speed 9600

Step 8 PressCtrl-Z to exit configuration mode.

Step 9 Copy the new console speed to NVRAM:

Router# copy run start

The new settings are saved to NVRAM, but they are not effective until the router restarts; for example, when you switch the power off and on or when you enter a reload command from the console.

Step 10 Enter theshow version command to display the configuration register value currently in effect and the value that will be used at the next reload. The value is shown on the last line of the display:

Configuration register is 0x142 (will be 0x142 at next reload)

Step 11 Reboot the router. The new value is effective after the router reboots.

Configuring the Boot Field

The lowest four bits of the configuration register (bits 3, 2, 1, and 0) form the boot field. (SeeTable C-2.)

Appendix C Configuration Register

Configuring the Boot Field

The boot field specifies a number in binary form. If you set the boot field value to 0, you must have console port access to boot the operating system manually. See the boot command in the“ROM Monitor Command Descriptions” section on page B-3.

If you set the boot field to a value of 2 to F, and a valid boot system command is stored in the configuration file, the router software processes eachboot command in sequence until the process is successful or the end of the list is reached. If noboot commands are in the configuration file, the router attempts to boot the first file in CompactFlash memory.

In the following example, the configuration register is set to boot the router automatically from CompactFlash memory and to ignore Break at the next reboot of the router:

Router# configure terminal

Enter configuration commands, one per line.

Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z

config-register0x102

Ctrl-z

Router#

Note Aboot system command in the router configuration in NVRAM overrides booting from CompactFlash memory.

Bit 8 controls the console Break key. Setting bit 8 (the factory default) causes the processor to ignore the console Break key. Clearing bit 8 causes the processor to interpret Break as a command to force the router into the bootstrap monitor, halting normal operation. Break can always be sent in the first

60 seconds while the router is rebooting, regardless of the configuration settings.

Bit 9 controls the system boot. Clearing bit 9 (the factory default) causes the system to boot from CompactFlash memory. Clearing bit 9 causes the system to use the secondary bootstrap. This bit is typically not used.

Bit 10 controls the host portion of the IP broadcast address. Setting bit 10 causes the processor to use all zeros; clearing bit 10 (the factory default) causes the processor to use all ones. Bit 10 interacts with bit 14, which controls the network and subnet portions of the broadcast address. Table C-3 shows the combined effect of bits 10 and 14.

Bit 13 determines how the router responds to a bootload failure. Setting bit 13 causes the router to load operating software from ROM after six unsuccessful attempts to load a boot file. Clearing bit 13 causes the router to continue indefinitely to attempt loading a boot file. By factory default, bit 13 is set to 0.

Bits 5, 11, and 12 of the configuration register determine th
