2-2
Cisco 2600 Series Hardware Installation Guide
Maintaining Safety with Electricity
Warning Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units.
Warning Do not touch the power supply when the power cord is connected. For systems
with a power switch, line voltages are present within the power supply even when the
power switch is OFF and the power cord is connected. For systems without a power
switch, line voltages are present within the power supply when the power cord is
connected.
Warning Incorrect connection of thisor connected equipment to a general purpose outlet
could result in a hazardous situation.
Warning This equipment is to be installed and maintained by service personnel only as
defined by AS/NZS 3260 Clause 1.2.14.3 Service Personnel.
Warning Read the installation instructions before you connect the system to its power
source.
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded
power extension cables, frayed power cords, and missing safety grounds.
• Locate the emergency power off switch for the room in which you are working. Then,
if an electrical accident occurs, you can act quickly to turn OFF the power.
• Power OFF the router and unplug the power cord before doing the following:
— Installing or removing a chassis
— Working near power supplies
• Do not work alone if potentially hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
Preparing to Install the Router 2-3
General Site Requirements
If an electrical accident occurs, proceed as follows:
• Use caution; do not become a victim yourself.
• Turn OFF power to the system.
• If possible, send another person to get medical aid. Otherwise, assess the condition of
the victim and then call for help.
• Determine if the victim needs rescue breathing or external cardiac compressions; then
take appropriate action.
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It
occurs when electronic components are improperly handled and can result in complete or
intermittent failures.
Always follow ESD-prevention procedures when removing and replacing components.
Ensure that the 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 safely channel unwanted ESD voltages to ground. To
properly guard against ESD damage and shocks, the wrist strap and cord must be used
effectively. If no wrist strap is available, ground yourself by touching the metal part of the
chassis.
Caution For safety,periodically check the resistance value of the antistatic strap, which
should be between 1 to 10 megohms (Mohm).
General Site Requirements
This section describes the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning
installation.
2-4
Cisco 2600 Series Hardware Installation Guide
Site Environment
The router can be placed on a desktop or mounted in a rack or 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.
When planning your site layout and equipment locations, remember the precautions
described in the next section, “Preventive Site Configuration.” If you are experiencing
shutdowns or unusually high errors with your existing equipment, these precautions might
help you isolate the cause of failures and prevent future problems.
Preventive Site Configuration
The followingprecautions will help you plan an acceptable operating environmentfor 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.
Site Environment
• Always follow the ESD-prevention procedures described in the “Preventing
Electrostatic Discharge Damage” section on page 2-4 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.
Configuring Equipment Racks
The following information will help you plan an acceptable 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.
Preparing to Install the Router 2-5
General Site Requirements
• When mounting a chassis in an open rack, ensure that the rack frame does not block the
intake 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 throughthechassis.The best placement of the baffles depends on the airflow patterns
in the rack, which can be found by experimenting with different arrangements.
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 to work with TN power systems.
2-6
Warning The telecommunications lines must be disconnected 1) before unplugging the
main power connector and /or 2) while the housing is open.
The router power supply includes the following features:
• Autoselects either 110V or 220V operation.
• Allunits include a 6-foot (1.8-meter) electrical power cord. (A label near the powercord
indicates the correct voltage, frequency, current draw, and power dissipation for the
unit.)
Warning This product relies on the building’s installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.
(240 VAC, 10A international) is used on the phase conductors (all current-carrying
conductors).
Cisco 2600 Series Hardware Installation Guide
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.
Networkconnection considerations are provided forseveral types ofnetwork interfaces and
are discussed in the following sections:
• Ethernet Connections on page 2-7
• Token Ring Connections on page 2-12
• Serial Connections on page 2-14
• ISDN BRI Connections on page 2-22
• 56K/Switched-56-kbps DSU/CSU Connections on page 2-23
Warning The Ethernet 10BaseT,TokenRing, console, and auxiliary ports contain safety
extra-low voltage (SELV) circuits. Avoid connecting SELV circuits to TNV circuits.
Ethernet Connections
The IEEE has established Ethernet as standard IEEE 802.3. The most common Ethernet
implementations are as follows:
Preparing to Connect to a Network
• 100BaseT—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45
cable.
• 10Base2—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum
segment distance is 607 feet (186 meters).
• 10Base5—Ethernetonthick coaxial cable, also known as thick Ethernet. The maximum
segment distance is 1,640 feet (500 meters).
• 10BaseT—Ethernet on 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.
The Ethernet interfaces available for the Cisco 2610, Cisco 2611, and Cisco 2612 routers
operate at speeds up to 10 Mbps. The Ethernet interfaces available for the Cisco 2620 and
Cisco 2621 routers operate at speeds up to 100 Mbps.

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 the shielded RJ-45 Token Ring cable when
connecting your router to your 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 the provided Token Ring cable to connect the router to a switch. Refer to the section
“Token Ring Port Pinouts” in the online document Cisco Modular Access Router CablingSpecifications for the Token Ring port pinouts. This document is on the Documentation
CD-ROM that accompanied your router package, and on Cisco Connection Online.
Preparing to Install the Router 2-13
Preparing to Connect to a Network
Serial Connections
Serial connections are provided by WANinterface 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, see the publication Cisco WAN Interface Cards Hardware
Installation Guide. Formore information on network modules, see the publication Network
ModulesHardwareInstallation Guide. Both of these publications accompanied your router
package.
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. (See Figure 2-8 through Figure 2-12, and
Figure 2-13.) 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 Table 2-1
to help you select the proper device type.
2-14
Cisco 2600 Series Hardware Installation Guide
Table 2-1Typical DTE and DCE Devices
Device typeGenderTypical Devices
DTEMale
DCEFemale
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.

Multiplexer
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.
Note All serial ports configured as DTE require external clocking from a CSU/DSU or
other DCE device.
Preparing to Install the Router 2-15
Preparing to Connect to a Network
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 online
document Cisco Modular Access Router Cabling Specifications on the Documentation
CD-ROM that accompanied your router, and on Cisco Connection Online.
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 2-2 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.
2-16
Table 2-2Serial Signal Transmission Speeds and Distances
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 Table 2-2 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.
EIA/TIA-232 Connections
EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. The networkend
of the adapter cable is a standard 25-pin D-shell connector known as a DB-25. (See
Figure 2-8.) The router console and auxiliary ports also use EIA/TIA-232 connections;
however, the serial module ports support synchronous connections, and the console and
auxiliary ports support asynchronous connections.
Serial Connections
Figure 2-8EIA/TIA-232 Adapter Cable Connectors, Network End
EIA/TIA-449 Connections
EIA/TIA-449, which supports balanced (EIA/TIA-422) and unbalanced (EIA/TIA-423)
transmissions, is a faster version of EIA/TIA-232 (up to 2 Mbps) that provides more
functions and supports transmissions over greater distances.

DCE
H1343a
Preparing to Install the Router 2-17
Preparing to Connect to a Network
The EIA/TIA-449 standard was intended to replace the EIA/TIA-232 standard, but it was
not widely adopted primarily because of the large installed base of DB-25 hardware and
because of the larger size 37-pin EIA/TIA-449 connectors, which limited the number of
connections possible (fewer than with the smaller, 25-pin EIA/TIA-232 connector).
The network end of the EIA/TIA-449 adapter cable provides a standard 37-pin D-shell
connector.(See Figure 2-9.) EIA/TIA-449 cables are available as either DTE (DB-37 plug)
or DCE (DB-37 receptacle).
Figure 2-9EIA/TIA-449 Adapter Cable Connectors, Network End
DTE
V.35 Connections
The V.35 interface is recommended for speeds up to 48 kbps, although it is often used
successfully at 4 Mbps.
The network end of the V.35 adapter cable provides a standard 34-pin Winchester-type
connector. (See Figure 2-10.) V.35 cables are available with a standard V.35 plug or
receptacle in either DTE or DCE mode.

X.21 Connections
The X.21 interface uses a 15-pin connection for balanced circuits and is commonly used in
the United Kingdom to connect public data networks. X.21 relocates some of the logic
functions to the DTE and DCE interfaces and, as a result, requires fewer circuits and a
smaller connector than EIA/TIA-232.
The network end of the X.21 adapter cable is a standard DB-15 connector. (See
Figure 2-11.) X.21 cables are available as either DTE (DB-15 plug) or DCE (DB-15
receptacle).

EIA-530 Connections
EIA-530, which supports balanced transmission, provides the increased functionality,
speed, and distance of EIA/TIA-449 on the smaller DB-25 connector used for
EIA/TIA-232, instead of the 37-pin connectors used for EIA/TIA-449. Like EIA/TIA-449,
EIA-530refers to the electrical specifications of EIA/TIA-422 andEIA/TIA-423. Although
the specification recommends a maximum speed of 2 Mbps, EIA-530 is used successfully
at 4 Mbps or faster over short distances.
The EIA-530 adapter cable is available in DTE mode only. The network end of the
EIA-530 adapter cable is a standard DB-25 plug commonly used for EIA/TIA-232
connections. Figure 2-12 shows the DB-25 connector at the network end of the
adapter cable.

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
availablewith either anS/T interface that requires an externalNetwork Terminator1 (NT1),
or a U interface that has a built-in NT1.
You can install the BRI modules into any available slot in the chassis.
Warning Network hazardous voltages are present in the BRI cable. If you detach the
BRI cable, detach the end away from the router first to avoid possible electric shock.
Networkhazardous voltages also are present on the system card in the area of the BRI port
(RJ-45 connector), regardless of when power is turned OFF.
Warning The ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Do not attempt to tamper with or open any public telephone
operator (PTO)-provided equipment or connection hardware. Any hardwired connection
(other than by a nonremovable, connect-one-time-only plug) must be made only by PTO
staff or suitably trained engineers.

Wiring the DC Power Supply
If you ordered a router with a DC power supply,follow the directions in this section to wire
the terminal block.
Warning Before performing any of the following procedures, ensure that power is
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker
on the panel board that services the DC circuit, switch the circuit breaker to the OFF
position, and tape the switch handle of the circuit breaker in the OFF position.
Warning The illustration shows the DC power supply terminal block. The proper wiring
sequence is ground to ground, positive to positive (line to L), and negative to negative
(neutral to N). Note that the ground wire should always be connected first and
disconnected last.
Warning When stranded wiring is required, use approved wiring terminations, such as
closed-loop or spade-type with upturned lugs. These terminations should be the
appropriate size for the wires and should clamp both the insulation and conductor.
Wiring the DC Power Supply
Caution Do not overtorque the terminal block captive thumbscrew or terminal block
contact screws. The recommended torque is 8.2 ± 0.4 inch-lb.
Warning After wiring the DC power supply, remove the tape from the circuit breaker
switch handle and reinstate power by moving the handle of the circuit breaker to the ON
position.
Warning Secure all power cabling when installing this unit to avoid disturbing
field-wiring connections.

Connecting the Console Terminal and Modem
Connecting the Console Terminal and Modem
Your router includes asynchronous serial console and auxiliary ports. These ports provide
administrative access to your router either locally (with a console terminal) or remotely
(with a modem).
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 3-14.) If your cable came from Cisco Systems, 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).

Take the following steps to connect a terminal (an ASCII terminal or a PC running terminal
emulation software) to the console port on the router:
Step 1Connect the terminal using the thin, flat, RJ-45-to-RJ-45 rollover cable (looks
like a telephone cable) and an RJ-45-to-DB-9 or RJ-45-to-DB-25 adapter
(labeled TERMINAL) included with the router. (See Figure 3-15.)
Step 2Configure your terminal or PC terminal emulation software for 9600 baud,
8 data bits, no parity, and 2 stop bits.
For information on console port pinouts, see the online document Cisco Modular AccessRouter Cabling Specifications on the Documentation CD-ROM that accompanied your

APPENDIX
Maintaining the Router
This appendix contains selected maintenance procedures you might need to perform on a
Cisco 2600 series router as your internetworking needs change.
This appendix includes the following sections:
• Upgrading DRAM on page B-2
• Opening the Chassis on page B-3
• Replacing the System-Code SIMM on page B-8
• Closing the Chassis on page B-11
Additional maintenance procedures are available on the Documentation CD-ROM that
shipped with the router.
B
To see translated versionsof warnings in this appendix, see the RegulatoryCompliance and
Safety Information document that accompanied your router.
Caution Before opening the chassis, be sure that you have discharged all static
electricity from your body and the power is OFF. Before performing any procedures
described in this appendix, review the “Safety Recommendations” section on page 2-1.
Warning Before working on a chassis or working near power supplies, unplug the power
cord on AC units; disconnect the power at the circuit breaker on DC units.
Maintaining the Router B-1
Upgrading DRAM
Upgrading DRAM
This section describes how to upgrade dynamic random-access memory (DRAM) on the
system card. You might need to upgrade DRAM for the following reasons:
• You have upgraded to a new Cisco IOS software feature set or release.
• You are using very large routing tables or many protocols (for example, when the router
is set up as part of both a large external network and your internal network).
To see how much memory is currently installed in the router, enter the show version
command. Near the middle of the resulting output, a message similar to the following
appears:
Cisco 2610(MPC860) processor (revision 0x200) with 28672K/4096K bytes of
memory.
This line shows how much memory is installed (in this example, 28672K/4096K). The first
number represents primary memory and the second number represents shared memory.
Cisco 2600 DRAM
Cisco 2600 series routers contain two 100-pin dual in-line memory module (DIMM)
sockets (or banks) for DRAM, numbered 0 and 1. (See Figure B-3.) Each socket can be
filled with a 100-pin DRAM DIMM. You can use the memory-size iomem software
command to configure DRAM as a mixture of shared memory, which is used for data
transmitted or receivedby network modules and WAN interface cards, and primary or main
memory,which is reserved for the CPU. For further information about this command, see
the Cisco IOS configuration guides and command references.

You will need the following tools to remove and replace the system-code SIMM on the
router:
• Medium-size flat-blade screwdriver (1/4 inch [0.625 cm])
There is one system-code (Flash memory) SIMM socket on the system board. You can
verify how much Flash memory is already installed in your router by entering the showflash EXEC command.
Caution The system code is stored on the Flash memory SIMM, but new system-code
SIMMs are shipped without preinstalled software. Before continuing with this procedure,
use the copy flash tftp EXEC command to back up the system code to a Trivial File
Transfer Protocol (TFTP) server.

Troubleshooting the Router
This appendix contains information about isolating problems with the router and includes
the following sections:
• Isolating Problems on page A-1
• Reading the LEDs on page A-3
For information about obtaining technical support, see the “Obtaining Service and
Support” on page ix .
Isolating Problems
The key to problem solving in this system is to try to isolate the problem to a specific
subsystem. By comparing what the system is doing to what it should be doing, the task of
isolating and solving the problem is greatly simplified.
APPENDIX
A
When problem solving, consider the following subsystems:
• Power and cooling systems—Power supply, power cable, and fan
• Ports, cables, and connections—Ports on the rear panel of the router and the cables that
connect to them
Troubleshooting the Router A-1
Isolating Problems
Troubleshooting the Power and Cooling Systems
Check the following items to help isolate the problem:
• When the power switch is in the ON position (|) and the power LED is on, make sure
the fan is operating. If not, check the fan.
• If the router shuts down after being on a short time, check the environmental conditions.
The router might be overheating, resulting in a thermal-induced shutdown. Ensure that
the chassis intake and exhaust vents are clear.Review the “General Site Requirements”
section on page 2-4. The operating temperature for the router is 32 to 104° F(0to40°C).
• If the router fails to boot, but the power LED is on, check the power supply.
• If the router constantly or intermittently reboots, there might be a problem with either
the processor or the software,or a DRAM single in-line memory module (SIMM) might
be installed incorrectly.
Troubleshooting the Ports, Cables, and Connections
Check the following items to help isolate the problem:
• If the router fails to recognize a port, check the cable connection.
A-2
• When the power switch is in the ON position (|), make sure the power LED is on. If not,
check the power source and power cable.
• If thesystemboots, but the console screen is frozen, verify that the console is configured
for 9600 baud, 8 data bits, no parity, and 2 stop bits.

APPENDIX
Using the ROM Monitor
Thisappendix describes using the ROM monitor (also called the bootstrap program), which
is the firmware that runs when you power on or restart a Cisco 2600 series router. During
normal operation, the ROMmonitor helps to initialize the processor hardware and boot the
operating system software. You can also use the ROM monitor to:
• Help you isolate or rule out hardware problems encountered when installing your router.
• Recover your router’s Cisco IOS image if the image becomes corrupted.
This appendix contains the following sections:
• Entering the ROM Monitor Mode on page C-1
• ROM Monitor Commands on page C-3
• ROM Monitor Syntax Conventions on page C-4
C
• Command Descriptions on page C-4
• Procedures for Recovering Boot and System Images on page C-9
Entering the ROM Monitor Mode
To use the ROM monitor, you must have access to the console port. See the Cisco 2600
Series Cabling and Setup quick start guide for information on connecting the console cable.
Using the ROM Monitor C-1
Entering the ROM Monitor Mode
To enter the ROM monitor mode, do the following:
Table C-1Entering ROM Monitor Mode
Step Command or ActionPurpose
12600> reload
2
Press the
while the system is starting up
Break key during the first 60 seconds
Restart the router.
Forces the router to stop booting and
enter the ROM monitor mode.
Verifying that You Are in ROM Monitor Mode
To verify that you are in the ROM monitor mode, check that the prompt displayed on your
screen is the ROM monitor mode prompt:
rommon # >
The # is the line number and increases incrementally at each prompt.
Tips
From the Cisco IOS software, you can configure the router to automatically enter the ROM
monitor mode the next time the router boots by setting virtual configuration register bits 3,
2, 1, and 0 to zero. From the console, enter the following configuration command:
configuration-register 0x0
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. Refer to the boot command in the “Command
Descriptions” section on page C-4.

ROM Monitor Syntax Conventions
ROM Monitor 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.
• Aterm 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 type interface
Command Descriptions
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 or b—Boot an image.
C-4
—bboots the first image in Flash memory.
—bflash:[name] boots the Cisco IOS software from the Flash memory.
—bfilename tftpserver boots from the specified file over the network from the
specified Trivial File Transfer Protocol (TFTP) server. For example:
boot c2600-i-mz 172.15.19.11
Cisco 2600 Series Hardware Installation Guide
Command Descriptions
—bfilename boots from the boothelper image because it does not recognize the
device ID. This form of the command is used to netboot the image named filename.
Cisco 2600 series routers do not have a dedicated boothelper image ([rx]boot) as
used by some other Cisco routers. WithCisco 2600 series routers, the first image in
Flash memory is invoked as the default boothelper image anytime the ROM
monitor does not recognize the device ID in the boot command.
You can override the default boothelper image setting by setting the BOOTLDR
monitor environment variable to point to another image. Any system image can be
used for this purpose.
Options to the boot command are -x, load image but do not execute, and -v, verbose.
Use the Cisco IOS commands show version and show hardware to display the source
of the currently running image.
• dir device:[partition:]—List the files on the named device. For example:
rommon 8 > dir flash:
File size Checksum File name
2229799 bytes (0x220627) 0x469e C2600-j-m2.113-4T
• help—Display a summary of ROM monitor commands (equivalent to ?).
• meminfo—Display size in bytes, starting address, available range of main memory, the
starting point and size of packet memory, and size of nonvolatile memory (NVRAM).
The following example shows the meminfo command:
rommon 9 > meminfo
Main memory size: 32 MB.
Available main memory starts at 0xa000e000, size 32704KB
IO (packet) memory size: 25 percent of main memory.
NVRAM size: 32KB

Debugging Commands
Most debugging commands are functional only when Cisco IOS software has crashed or is
aborted. 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, can not proceed.”
• stack or k—Produce a stack trace.
• context—Display processor context.
• frame—Display an individual stack frame.
• sysret—Display return information from the last booted system image. This
information includes the reason for terminating the image, a stack dump of up to eight
frames, and, if an exception is involved, the address where the exception occurred. For
example:
Thevirtualconfiguration register resides in NVRAM. Youcan displayormodify the virtual
configuration register from either the ROM monitor or the operating system software.
To change the virtual configuration register from the ROM monitor, enter confreg by itself
for menu mode, or enter the new value of the register in hexadecimal.
• confreg[hexnum]—Change the virtual configuration register to thevalue specified. The
value is always interpreted as hexadecimal. Entering confreg without an argument
displays the contents of the virtual configuration register and prompts you to alter the
contents by describing the meaning of each bit.
Using the ROM Monitor C-7
Command Descriptions
In either case, the new virtual configuration register value is written into NVRAM, but
is not effective until you reset or power-cycle the router.
The following display shows an example of the confreg command:

Procedures for Recovering Boot and System Images
Procedures for Recovering Boot and System Images
If your Cisco 2600 series router experiences difficulties and no longer contains a valid
Cisco IOS software image in Flash memory, you can recover the Cisco IOS image using
one of the following ROM monitor commands:
• xmodem—Use this if the computer attached to your console has a terminal emulator
that has Xmodem capability.
• tftpdnld—Use this if you have a TFTP server directly connected to the Ethernet 0 port
or Token Ring 0 port.
Using the xmodem Command
The xmodem command establishes a connection between a console and the router console
portfor disaster recovery if both the boot andsystem images are erased from Flash memory.
xmodem [filename]—Establishes an Xmodem connection between the console and the
router. The optional parameter 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
Using the ROM Monitor C-9
Procedures for Recovering Boot and System Images
Using the tftpdnld Command
The tftpdnld command downloads a Cisco IOS software image from a remote server
accessible from an Ethernet or TokenRing network interface on a Cisco 2600 series router.
The tftpdnldcommand downloadsthe Cisco IOS software image into Flash memory using
TFTP.
The following software restrictions apply when using the tftpdnld command:
• Ethernet platform—Only accepts and sends Ethernet V2.0 data packets.
• Token Ring platform—Only accepts and sends 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 serveron 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.
tftpdnld [-h] [-r]—Begins the TFTP copy procedure.
Options include the following:
• h—Displays the tftpdnld command help screen.
• r—Loadsthe Cisco IOS software image only to DRAM and launches theimage without
writing the image into Flash memory.
C-10
The tftpdnld command requires that you specify certain variables when you issue the
command. The syntax for specifying the variables is:
VARIABLE_NAME=value
The variables that you must specify include the following:
• IP_ADDRESS—IP address for the router you are using.
• IP_SUBNET_MASK—Subnet mask for the router you are using.
• DEFAULT_GATEWAY—Default gateway for the router you are using.
• TFTP_SERVER—IP address of the server from which you want to downloadthe image
file.
• TFTP_FILE—Name of the file that you want to download.
Cisco 2600 Series Hardware Installation Guide
Using the tftpdnld Command
The following tftpdnld command variables are optional:
• TFTP_VERBOSE—Print setting. The default is 1.
— 0=quiet—After you enter the tftpdnld command, the prompt
Do you wish to continue? y/n:
is the only information that displays until the command completes successfully or
fails.
— 1=progress—Displays the state of the required tftpdnld command variables. Also
displays progress characters to indicate successful and lost packet transmissions.
— 2=verbose—Displays all progress print setting messages, along with error
information. The information provided by this print setting may be useful when
debugging interface link and configuration problems that may prevent connecting
to the TFTP server.
• TFTP_RETRY_COUNT—Number of times from 1 to 65535 that the ROM monitor
will retry ARP and ACK. The default is 7.
• TFTP_TIMEOUT—Overall timeout of the download operation in seconds. The range
is from 1 to 65535 seconds. The default is 7200 seconds.
• TFTP_CHECKSUM—Performs a checksum test on the image. 0=checksum off,
1=checksum on. The default is 1.
• FE_SPEED_MODE—Sets the Fast Ethernet speed and duplex mode. 0=10 Mbps
half-duplex mode, 1=10 Mbps full-duplex mode, 2=100 Mbps half-duplex mode,
3=100 Mbps full-duplex mode, 4=auto-negotiation. The default is 4.
Note Specify the FE_SPEED_MODE variable only for routers with a Fast Ethernet
network interface.
Using the ROM Monitor C-11
Procedures for Recovering Boot and System Images
• TR_SPEED_MODE—Sets the Token Ring speed and duplex mode. 0=4 Mbps
half-duplex mode, 1=4 Mbps full-duplex mode, 2=16 Mbps half-duplex mode, 3=16
Mbps full-duplex mode. The default is 2.
Note Specify the TR_SPEED_MODE variable only for routers with a Token Ring
network interface; or for routers with both an Ethernet and a Token Ring port, those
routers that are set to use the Token Ring port with the tftpdnld command.
• TR_1E1R_PORT—Sets the port to be used with the tftpdnld command. 0=Use
Ethernet port, 1=Use Token Ring port. The default is 0.
Note Specify the TR_1E1R_PORT variable only for those routers with both an
Ethernet and a Token Ring port.
After you specify the variables, you must reenter the tftpdnld command. For example:
