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-frequency energy 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-frequency energy. 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.

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

Severity 1 (S1)—Your network 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)—Operation of 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 commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance 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.

Obtaining Additional Publications and Information

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

In addition to the interfaces listed in Tabl e 1-1, Cisco 2600 series routers include the following hardware features:

• Dynamic random-access memory (DRAM) for main memory and shared memory (Cisco 261x and

Cisco 262x routers)

• Synchronous dynamic random-access memory (SDRAM) for main memory and shared memory

(Cisco 26xxXM, Cisco 265x, and Cisco 2691 routers)

• Nonvolatile random-access memory (NVRAM) for storing configuration information

• Flash memory—Stores the operating system software image. In Cisco 2691 routers, flash memory

is a CompactFlash memory card. In all other Cisco 2600 series routers, flash memory is a single inline memory module (SIMM).

• EIA/TIA-232 (RJ-45) console port for local system access by using a console terminal

• EIA/TIA-232 (RJ-45) auxiliary port for remote system access or dial backup by using a modem

Figure 1-1 and Figure 1-2 show examples of Cisco 2600 series routers.

Interface Numbering

Each interface (port) on a Cisco 2610, Cisco 2620, and Cisco 2650 series router is identified by number as described in the following sections.

Interface Numbering

WAN and LAN Interface Numbering

Cisco 2600 series routers contain the following WAN and LAN interface types:

• Built-in LAN interfaces: Ethernet, FastEthernet, Token Ring

• Two or three slots in which you can install WAN interface cards (WICs)

• One slot in which you can install a network module

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

• Ethernet 0/0

• Serial 1/2

The slot number is 0 for all built-in interfaces and 0 for all WIC interfaces; the slot number is 1 for network module interfaces.

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

Figure 1-11 shows a router of 1-RU height with:

• A WIC in each WIC slot (containing interface Serial 0/0 in physical slot W0, and interface Serial

0/1 in physical slot W1)

• A 4-serial-port network module in slot 1 (containing the following ports: Serial 1/0, Serial 1/1,

Serial 1/2, and Serial 1/3)

• First built-in Ethernet interface—Ethernet 0/0

• Second built-in Ethernet interface—Ethernet 0/1, or optionally in Cisco 2612 and Cisco 2613

routers only: Token Ring interface 0/0

• Safety Recommendations, page 2-1

• General Site Requirements, page 2-3

• Installation Checklist, page 2-4

• Creating a Site Log, page 2-5

• Inspecting the Router, page 2-6

• Tools and Equipment for Installation and Maintenance, page 2-6

• Console and Auxiliary Port Considerations, page 2-7

• Preparing to Connect to a Network, page 2-8

After you have completed this chapter, proceed to Chapter 3, “Installing the Router” for installation instructions.

Safety Recommendations

Follow these guidelines to ensure general safety:

• Keep the chassis area clear and dust-free during and after installation.

• If you remove the chassis cover, put it in a safe place.

• Keep tools and chassis components away from walk areas.

• Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up

your sleeves.

• Wear safety glasses when working under conditions that might be hazardous to your eyes.

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

Safety with Electricity

Follow these guidelines when working on equipment powered by electricity:

Warning

OL-2171-06

Read the installation instructions before connecting the system to the power source.

Statement 1004

Cisco 2600 Series Routers Hardware Installation Guide

Safety Recommendations

Chapter 2 Preparing to Install the Router

• Locate the emergency power-off switch 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-preventive wrist 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.

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).

Chapter 2 Preparing to Install the Router

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.

General Site Requirements

Warning

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

The AC power supply includes the following features:

• 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

Table 2- 1 describes power requirements for Cisco 2600 series routers.

Table 2-1 Power Requirements for Cisco 2600 Series Routers

Power Source Input Power

AC 100 - 240 VAC, 1.0 A, 50 - 60 Hz 85 - 264 VAC

DC 48 - 60 VDC, 3.0 A 38 - 72 VDC

Site Environment

The router can be placed on a desktop or mounted in a rack. Single rack-unit (1RU) routers can also be mounted on a wall. The location of the chassis and the layout of your equipment rack or wiring room are extremely important for proper system operation. Placing equipment too close together, inadequate ventilation, and inaccessible panels can make system maintenance difficult or cause system malfunctions and shutdowns.

Statement 1007

the correct voltage, frequency, current draw, and power dissipation for the unit.)

Input Voltage Tolerance Limits

OL-2171-06

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 unusually high errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Cisco 2600 Series Routers Hardware Installation Guide

2-3

Installation Checklist

Site Configuration

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

• Ensure that the room in which you operate your system has adequate air circulation. Electrical

equipment generates heat. Ambient air temperature might not be able to cool equipment to acceptable operating temperatures without adequate circulation.

• Always follow the ESD-prevention procedures 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 is secure. The chassis is designed to allow cooling air to flow

effectively inside it. An open chassis allows air leaks, which might interrupt and redirect the flow of cooling air from internal components.

Equipment Racks

Cisco 2600 series routers with chassis height of 1 RU can be installed in 19-, 23-, and 24-inch racks.

Chapter 2 Preparing to Install the Router

Cisco 2600 series routers with chassis height of 2 RU can be installed in 19- or 23-inch racks.

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

• Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested, because

each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake ports

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

• In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the

bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure that you provide adequate ventilation for equipment at the bottom of the rack.

• 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 arrangements.

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”).

• Needlenose pliers

–

For straightening any pins bent when you install the ROM

• Cable ties, if required, for organizing cables

To install a Cisco 2600 router of 1 rack-unit height on a wall, you need suitable screws or wall anchors.

In addition, depending on the type of modules you plan to use, you might need the following equipment to connect a port to an external network:

• Cables for connection to the WAN and LAN ports (dependent on configuration).

Note For more information on cable specifications, refer to the Cisco Modular Access Router

• Ethernet hub or PC with a network interface card for connection to Ethernet (LAN) ports.

• Console terminal (an ASCII terminal or a PC running terminal emulation software) configured for

9600 baud, 8 data bits, no parity, and 1 stop bit.

• Modem for connection to the auxiliary port for remote administrative access (optional).

• Token Ring interfaces require a Token Ring media attachment unit (MAU).

Console and Auxiliary Port Considerations

Cable Specifications document online or on the Documentation CD-ROM.

• Serial interfaces may require a data service unit (DSU) or channel service unit/data service unit

(DSU/CSU).

• CT1/PRI modules without the built-in CSU require an external CSU.

• ISDN BRI S/T interfaces require an NT1 device if one is not supplied by your service provider.

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, or remotely using a modem connected to the auxiliary port. This section discusses important cabling information to consider before connecting a console terminal, which can be either an ASCII terminal or a PC running terminal emulation software, to the console port or modem to the auxiliary port.

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-speed transmissions of a modem. Console terminals transmit 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-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port appears 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-45 to DB-9 adapter cable.

OL-2171-06

2-7

Preparing to Connect to a Network

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

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console port does not support hardware flow control. For detailed information about installing a console terminal, refer to the “Connecting to a Console Terminal or Modem” section on page 3-20.

For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.

Auxiliary Port Connections

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port appears 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-25 adapter cable.

For detailed information about connecting devices to the auxiliary port, refer to the “Connecting to a

Console Terminal or Modem” section on page 3-20.

Chapter 2 Preparing to Install the Router

For cable and port pinouts, refer to the Cisco Modular Access Router Cable Specifications document online or on the Documentation CD-ROM.

Preparing to Connect to a Network

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

Network connection considerations are provided for several types of network interfaces and are described in the following sections:

Ethernet Connections

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

• 100BASE-T—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable.

• 10BASE-2—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment

distance is 607 feet (186 meters).

• 10BASE-5—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment

distance is 1,640 feet (500 meters).

• 10BASE-T—Ethernet on unshielded twisted-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.

Table 2- 2 lists the router models described in this guide and summarizes the LAN interfaces supported

on each model.

Preparing to Connect to a Network

Note To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make

sure that you use a shielded RJ-45 Token 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. Refer to the section “Token Ring Port Pinouts” in the Cisco Modular Access Router Cable Specifications online document for the Token Ring port pinouts. This document is available online and on the Cisco Documentation CD-ROM.

Serial Connections

Serial connections are provided by WAN interface cards and network modules. The WAN interface cards can be installed in either slot of the 2-slot chassis; the network module can be installed in the Cisco 2600 series single network module slot. For more information on WAN interface cards, refer to the Cisco Interface Cards Hardware Installation Guide. For more information on network modules, refer to the Cisco Network Modules Hardware Installation Guide. These documents are accessible online and on the Cisco Documentation CD-ROM.

Installation Guide.

Chapter 2 Preparing to Install the Router

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

• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are

connecting to the synchronous serial interface

• Type of connector, male or female, required to 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-60 connectors. 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 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.) If you cannot determine the device type in the documentation, see Tab le 2- 3 to help you select the proper device type.

Chapter 2 Preparing to Install the Router

Table 2-3 Typical DTE and DCE Devices

Device Type Gender Typical Devices

DTE Male

DCE Female

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, and EIA-530. You can order a Cisco DB-60 shielded 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 a DB-60 connector, which connects to the DB-60 port 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

Documentation” section on page xvii.

DSU/CSU

Multiplexer

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

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

Cable Specifications.

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- 4 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.

Balanced drivers allow EIA/TIA-449 signals to travel greater distances than EIA/TIA-232 signals. The recommended distance limits for EIA/TIA-449 shown in Ta ble 2- 4 are also valid for V.35, X.21, and EIA-530. Typically, EIA/TIA-449 and EIA-530 can support 2-Mbps rates, and V.35 can support 4-Mbps rates.

Asynchronous/Synchronous Serial Module Baud Rates

The following baud-rate limitations apply to the slow-speed serial interfaces found in the asynchronous/synchronous serial modules:

• Asynchronous interface—Maximum baud rate is 115.2 kbps.

• Synchronous interface—Maximum baud rate is 128-kbps full 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 Terminator 1 (NT1), or a U interface that has a built-in NT1.

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

Mounting the Chassis on the Wall

This section explains how to mount Cisco 2600 series routers with a chassis height of 1RU on a wall. Mounting a 2-RU chassis to a wall is not recommended, and brackets are not provided for mounting to a wall.

Setting Up the Chassis

Tip When choosing a wall-mounting location, consider cable limitations and wall structure.

Use 19-inch brackets (shown in Figure 3-2) to wall-mount the chassis. The small brackets provide the most stable installation for the chassis. The rubber feet are required to provide spacing between the wall and the router for ventilation and proper cooling.

Attaching Rubber Feet to the Router

Attach the rubber feet supplied in the accessory kit. See Figure 3-1 on page 3-4 for positioning the rubber feet.

Attaching Wall-Mount Brackets to the Router

To install the router on a wall, first attach the brackets on each side of the chassis as shown in

Figure 3-16, using plastic washers and slotted hex-head screws. Position the washers so that the narrow

shoulder faces the router chassis.

Note The hex-head screws and plastic washers are used only for wall-mounting the router. For rack-mounting,

the brackets are attached using Phillips-head screws, without washers.

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. Hold 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 3-25.) 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).

Isolating Problems

• Modules—LEDs on the modules can help identify a failure.

• Cables—External cables 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 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 a short time?

System Messages

This section describes system error and recovery messages that may appear when operating a Cisco 2600 series router. Error messages for Cisco 2600 series routers powered by the Cisco redundant power system are described in the publication Cisco RPS Installation Guide.

The 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 3-20.)

The terminal should display one of the following prompts:

Router> (indicates user EXEC mode)

Router# (indicates privileged EXEC mode)

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

To see descriptions of the system error and recovery messages and LED conditions that might accompany them, refer to the Cisco IOS System Error Messages online document at the following URL:

APPENDIX

Using the ROM Monitor

This appendix describes the use of the ROM monitor (also called the bootstrap program), which is the firmware that runs when you power up or restart a Cisco router. 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:

• Help isolate hardware problems encountered when installing your router.

• Download a new Cisco IOS image if the operating image is corrupted.

This appendix contains the following sections:

• Entering ROM Monitor Mode, page B-1

• ROM Monitor Commands, page B-2

• ROM Monitor Command Syntax Conventions, page B-3

• ROM Monitor Command Descriptions, page B-4

• 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. Refer to the “Connecting to a

Console Terminal or Modem” section on page 3-20 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 for one-time use.

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

the Break key.

Note If your console terminal does not have a Break key, refer to 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.

OL-2171-06

Cisco 2600 Series Routers Hardware Installation Guide

B-1

ROM Monitor Commands

As long as the configuration register value remains 0x0, you must manually boot the operating system from the console. Refer to the boot command in the “ROM Monitor Command Descriptions”

section on page B-4.

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 the reload command.

Router# reload

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

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

rommon 1>

Appendix B Using the ROM Monitor

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-register 0x0

Step 2 Restart the router with the reload command:

The router boots into the 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.

To display information about command syntax, enter the command name followed by -?.

Entering ROM Monitor Commands

ROM monitor commands are case-sensitive. Enter commands exactly as shown.

Interrupting ROM Monitor Commands

You can end any command by generating a Break (system interrupt) at the console.

ROM Monitor Command Syntax Conventions

The 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

OL-2171-06

Cisco 2600 Series Routers Hardware Installation Guide

B-3

ROM Monitor Command Descriptions

Router Management Commands

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

Boot Commands in the ROM Monitor

Functions of Boot Commands

The router always boots first from a Cisco IOS image in flash memory, because there is no separate, dedicated boothelper image ([rx]boot). The first image in flash memory functions as the boothelper image, but you can override this by setting the BOOTLDR Monitor environment variable to point to another image. If the ROM monitor does not recognize a device ID specified in the boot command (device does not exist, or command entered incorrectly), the router boots from the first image in flash memory.

Appendix B Using the ROM Monitor

To boot a router from a Cisco IOS image on a TFTP server (netboot), the installed DRAM must be adequate to hold two uncompressed Cisco IOS images: the image from flash 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 flash memory. It decompresses that image in DRAM, parses the boot system commands, downloads the Cisco IOS image from the TFTP server, and decompresses it in DRAM. After the Cisco IOS image from the TFTP server is in DRAM, the DRAM memory occupied by the boothelper image is released.

Note Booting from a TFTP server is useful if the router does not have enough flash memory to hold large

images. With a small image in flash memory (just large enough to support the necessary interfaces), the router boots from flash memory, and then the larger image is downloaded from the TFTP server.

Entering Boot Commands

The boot command syntax is as follows, where:

boot [flash: [partition: [filename]] | slot0: [partition: [filename]] | slot1: [partition: [filename]] |

filename tftpserver] [-x] [-v]

Some examples of boot commands are as follows:

• partition is a partition number in the flash memory.

• filename is the Cisco IOS image filename.

• 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.

B-4

Note In all boot commands, boot can be entered as b.

Configuration Register Commands

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, you can:

ROM Monitor Command Descriptions

• Enter the confreg command by itself for menu mode. See the “Modifying the Configuration

• Enter the confreg command plus the new hexidecimal value of the configuration register. See the

“Modifying the Configuration Register by Hexidecimal Entry” section on page B-8.

In either case, the new configuration register value is written into NVRAM, but is not effective until you reboot (using the ROM monitor reset command) or power cycle the router.

Modifying the Configuration Register in Menu Mode

Entering the confreg command without an argument displays the contents of the configuration register, and prompts you to alter the contents by describing the meaning of each bit.

The following display shows an example of the confreg command:

Entering the confreg command plus a hexidecimal value changes the contents of the configuration register. The syntax is confreg [hexnum]; values entered are always interpreted as hexadecimal. The following example changes the value of the configuration register to the factory default:

rommon 7> confreg 0x2102

Appendix B Using the ROM Monitor

You must reset or power cycle the router for new configuration to take effect.

Recovering Cisco IOS Software Images

If your Cisco router experiences difficulties and no longer contains a valid Cisco IOS software image in flash memory, you can download a new Cisco IOS image using one of the following ROM monitor commands:

• xmodem—(All Cisco 2600 series routers) Use this command to copy a Cisco IOS image from the

console, if the computer attached to your console has a terminal emulator with Xmodem capability. See the “Copying an Image from the Console Using the xmodem Command” procedure on

page B-9.

Note Downloading a Cisco IOS image from a console is very slow. This procedure should be used

only in an emergency and is not recommended for normal Cisco IOS image upgrades.

For the fastest possible download from a console, set the console speed to 115200 bps by using the confreg ROM monitor command. See the “Configuration Register Commands”

procedure on page B-7.

• tftpdnld—(Except Cisco 2691) Use this command to copy a Cisco IOS image from a TFTP server

that is accessible through the FastEthernet 0/0, Ethernet 0/0, or Token Ring 0/0 port. See the

“Copying an Image from a TFTP Server Using the tftpdnld Command” procedure on page B-10.

Appendix B Using the ROM Monitor

Recovering Cisco IOS Software Images

Note The tftpdnld command is not available on the Cisco 2691 router. The recommended method

for installing a Cisco IOS image on a Cisco 2691 router is from a CompactFlash memory card loaded in the external CompactFlash memory card slot. See the “Entering Boot

Commands” procedure on page B-4.

Copying an Image from the Console Using the xmodem Command

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 flash memory.

xmodem [filename]—Establishes an Xmodem connection between the console and the router. The optional argument filename specifies the source file containing the Cisco IOS image.

Other options include the following:

• c—Use cyclic redundancy check (CRC-16).

• y—Use Ymodem transfer protocol.

• r—Copy the image to dynamic random-access memory (DRAM) for launch.

• x—Do not launch image on completion of download.

Console Requirements

The console computer (PC) 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

• Cisco IOS image file

Procedure for the xmodem Command

To copy a Cisco IOS image from a console to flash memory, perform the following procedure.

Note File transfer from a console is slow and will take many minutes.

OL-2171-06

Step 1 Connect a console to the router’s console port using the instructions in the “Connecting to a Console

Terminal or Modem” section on page 3-20.

Step 2 Power up the router. The power-on self-test diagnostics run and the boot ROM searches for a valid boot

image and Cisco IOS image in flash memory. If the boot image and Cisco IOS image are not found, the ROM monitor prompt is displayed:

rommon 1>

Cisco 2600 Series Routers Hardware Installation Guide

B-9

Recovering Cisco IOS Software Images

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

rommon 1> xmodem

When the source file is found, messages similar to the following appear:

Do not start upload program yet... File size Checksum File name 2537948 bytes (0x26b9dc) c2600-i-mz.122-10.bin

WARN: This operation will ERASE bootflash. If the xmodem download to bootflash fails, you will lose any good image you may already have in bootflash. Invoke this application only for disaster recovery.

Do you wish to continue? [yes/no]:

Step 4 Enter yes to copy the Cisco IOS image into flash memory. Messages similar to the following appear:

Ready to receive file prog ...

Erasing flash at 0x3000000

program flash location 0x3000000

Appendix B Using the ROM Monitor

filename

Transfer complete!

The router is now ready to boot from the Cisco IOS image. Enter the reset ROM monitor command to reboot the router.

Note If you have set the console speed to 115200, you may want to reset it to the previous speed or to the

factory default speed (typically 9600 bps). See the “Configuration Register Commands” procedure on

page B-7.

Copying an Image from a TFTP Server Using the tftpdnld Command

The tftpdnld command downloads a Cisco IOS software image from a remote server accessible from a FastEthernet, Ethernet, or Token Ring network interface on a Cisco 2600 series router (except Cisco

2691). The tftpdnld command downloads the Cisco IOS software image into flash memory using TFTP.

Restrictions on the tftpdnld Command

The following software restrictions apply when using the tftpdnld command:

• Ethernet and FastEthernet—Accepts and sends only Ethernet V2.0 data packets.

B-10

• Token Ring—Accepts and sends only Token Ring frames with IEEE802.3 SNAP frames. Does not

support any frames with routing information fields (RIFs), limiting all use of the tftpdnld command to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must establish a path to the server through a router or transparent bridge from the local ring.

Cisco 2600 Series Routers Hardware Installation Guide

OL-2171-06

Appendix B Using the ROM Monitor

Procedure for the tftpdnld Command

Step 1 Specify the required variables, for example:

Changing Configuration Register Settings

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

• Recover a lost password

Appendix C Configuration Register

• 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 flash 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 from either the ROM monitor or the operating system software. To change the configuration register from the ROM monitor, see the “Configuration Register

Commands” section on page B-7. To change the configuration register from the system software, do the

following:

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 3-20, using the blue RJ-45 to DB-9 console adapter cable.

Note If you have a terminal with a DB-25 port, use an RJ-45 rollover cable and DB-25 adapter. The

RJ-45-to-DB-25 adapter (Cisco part number 29-0810-01) can be purchased from Cisco.

For information about cable pinouts, refer to the online document Cisco Modular Access Router Cable

Specifications. This document is available online and on the Cisco Documentation CD-ROM.

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

and 1 stop bit.

Step 3 Power on the router. Step 4 When asked if you would like to enter the initial dialog, answer no:

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

C-2

Your router is now in the normal operating mode.

Step 5 After a few seconds, you see the user EXEC prompt (Router>). Enter the enable command and your

password to enter privileged EXEC mode:

Cisco 2600 Series Routers Hardware Installation Guide

OL-2171-06

Appendix C Configuration Register

Router> enable

Configuring the Boot Field

Password:

Step 6 At the privileged EXEC prompt (Router#), enter the configure 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 the config-register value command, where value is a hexadecimal number preceded by 0x (see

password

Table C- 2 ), to set the contents of the configuration register:

Router# config-register 0x

Note Cisco IOS software does not allow you to change the console speed bits directly with the

value

config-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 Press Ctrl-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 the show 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. (See Table C-2.)

Table C-2 Explanation of Boot Field Configuration Register Bits (00-03)

Boot Field Meaning

00 Stays at the ROM monitor on a reload or power cycle

01 Boots the first image in flash memory as a system image

02-F Enables default booting from flash memory

Enables boot system commands that override default booting from flash memory

OL-2171-06

Cisco 2600 Series Routers Hardware Installation Guide

C-3

Configuring the Boot Field

Note A boot system command in the router configuration in NVRAM overrides booting from flash memory.

Appendix C Configuration Register

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. Refer to the boot command in the “ROM

Monitor Command Descriptions” section on page B-4.

If you set the boot field to a value of 2 to F, and there is a valid boot system command stored in the configuration file, the router software processes each boot command in sequence until the process is successful or the end of the list is reached. If there are no boot commands in the configuration file, the router attempts to boot the first file in flash memory.

In the following example, the configuration register is set to boot the router automatically from flash 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-register 0x102 Ctrl-z

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 flash memory. Clearing bit 9 causes the system to use the secondary bootstrap (netbooting). This 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. Ta ble C- 3 shows the combined effect of bit 10 and bit 14.

Table C-3 Configuration Register Settings for Broadcast Address Destination

Bit 10 Bit 14 Address (<net> <host>)

Off Off <ones> <ones>

On Off <zeros> <zeros>

On On <net> <zeros>

Off On <net> <ones>

Bit 13 determines the router’s response 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.

Bit 5, bit 11, and bit 12 of the configuration register determine the baud rate of the console terminal.

Table C- 4 shows the bit settings for the eight available rates. (The default baud rate is 9600 bps.)

Enabling Booting from Flash Memory

To enable booting from flash memory, set bits 3, 2, 1, and 0 to a value between 2 to 15. To specify a filename to boot, enter the system software configuration command boot system flash [device:] [partition:] [filename] in the configuration file.

By specifying the device and partition in the command, you can configure the router to boot from the PCMCIA cards. If you specify only the filename, the router is configured to boot from flash memory.

To enter configuration mode while in the system software image, enter the configure command at the enable prompt as in the following example:

Router# configure

Enabling Booting from Flash Memory

Configuring from terminal, memory, or network [terminal]? terminal

Enter configuration commands, one per line. Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z

boot system flash filename

To disable Break and enable the boot system flash command, enter the config-register command with a value as follows:

config-reg 0x102 Ctrl-z

If you set the configuration register value to 0x102, as in this example, you do not need to enter the boot system flash command unless there is more than one image in flash memory.
