BootROM Installation for Cisco 2620 and
Cisco 2621 Routers
Product Numbers:
MEM2620-32FSBOOT=
This document describes the procedures for replacing the BootROM in a Cisco 2620 or Cisco 2621
router. Cisco 2620 and Cisco 2621 routers can be upgraded to support a maximum of 32MB of Flash
memory when using both the Cisco 2600 BootROM version 12.1(3r)T2 (supplied with Cisco p/n
MEM2620-32FSBoot=) and Cisco IOS Release 12.1.3T, 12.2, 12.2T, or later Cisco IOS versions.
Note You can upgrade the BootROM to support 32MB Flash in the following routers: Cisco 2620 and
Cisco 2621.
Cisco 2620XMand Cisco 2621XM routers already support 32MB Flash; they do not require a BootROM
upgrade.
Additional information about Cisco 2600 series routers is in the Cisco 2600 Series Routers Hardware
Installation Guide. This document can be accessed on the Documentation CD-ROM or online through

Opening the Chassis
Warning
Warning
Note When a procedure refers to the left side or right side of the chassis, it means as viewed from the front.
Only trained and qualified personnel should be allowed to install or replace this equipment.
Before performing any procedures described in this document, review the Safety Recommendations
in your Regulatory Compliance and Safety Information document.
Opening the Chassis
This section describes the procedure for opening the chassis by removing the chassis cover.
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. To see translations of the warnings that appear in this
publication, refer to the
this device.
Regulatory Compliance and Safety Information

Warning
Tools Required
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. To see translations of the warnings that appear in this publication,
refer to the
Statement 1032
Regulatory Compliance and Safety Information
document that accompanied this device.
You will need the following tools to remove and replace the BootROM on the router:
• Number 2 Phillips screwdriver
• Electrostatic discharge (ESD)-preventive wrist strap
• BootROM required for your planned upgrade

Removing the Chassis Cover
You must open the chassis to access the internal components.
Opening the Chassis
Warning
Before opening the chassis, disconnect the telephone-network cables to avoid contact with
telephone-network voltages.
To remove the chassis cover:
Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
equipment end of the wrist strap to the metal backplane of the chassis, avoiding contact with the
connectors.
Step 2 Power OFF the router.
Step 3 Disconnect all cables from the rear panel of the router.
Step 4 Remove the screws located on the top of the chassis. Note that the chassis is comprised of two sections:
top and bottom.
Step 5 Holding the chassis with both hands, position it as shown in Figure 1.
Step 6 Slide the top section away from the bottom section as shown in Figure 2. Set the cover aside.

Replacing the ROM
Replacing the ROM
To upgrade the router ROM software to a new ROM monitor version, you must replace the existing
ROM. Follow this procedure to replace the ROM:
Caution Correct placement of the ROM is crucial. If improperly positioned, the new component could be
damaged when the router is powered on. Read all instructions before proceeding. To prevent damage to
the ROM from ESD (when handling the router and its components), follow the ESD procedures
described in your hardwareguide and see the Regulatory Compliance and Safety Information document.
Be careful not to damage or scratch the printed circuit card under the ROM.
Step 1 Locate the ROM on the system board (motherboard) layout as shown in Figure 3.
Step 2 Gently remove the old ROM with a ROM extraction tool or a small flat-blade screwdriver, and set it
aside.

Step 3 Orient and insert the new ROM in its socket as shown in Figure 3, being careful to not bend or crush any
of the bottom pins. To straighten out a bent pin, use needlenose pliers. Align the notch in the new ROM
with the notch in the ROM socket, ignoring the orientation of the label.
Caution The notch on the ROM must match the notch on the socket on the system board. Installing the ROM
backward will damage it.
Closing the Chassis
Close the chassis by replacing the cover:
Step 1 Position the two chassis sections, as shown in Figure 2.
Step 2 Referring to Figure 2, press the two chassis sections together and verify the following:
• The top section fits into the rear of the bottom section. The bottom section fits into the front of the
top section.
• Each side of the top and bottom sections fits together.
Closing the Chassis
Caution To fit the twosections together, it might be necessaryto work them together atone end and then theother,
working back and forth; however, use care to prevent bending the chassis edges.
Step 3 When the two sections fit together snugly, slide the chassis top so it fits into the front bezel.
Step 4 Replace the cover screws. Tighten the screws to no more than 8 or 9 inch/pound of torque.
Step 5 Reinstall the chassis on the wall, rack, desktop, or table.
Step 6 Reconnect all cables.
Testing ROM Installation
Test your installation by rebooting the router. If you installed the ROM correctly, the router will boot
into the ROM monitor or operating system.
If you suspect that the ROM is inserted incorrectly, remove and reinstall the ROM as described in the
“Replacing the ROM” section on page 4. Reboot the router again.

Opening a TAC Case
Using the online TAC Case Open Tool (http://www.cisco.com/tac/caseopen) is the fastest way to open
P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which
you require product information.) After you describe your situation, the TAC Case Open Tool
automatically recommends resources for an immediate solution. If your issue is not resolved using the
recommended resources, your case will be assigned to a Cisco TAC engineer.
For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely
degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers
are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.
To open a case by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—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.
Priority 2 (P2)—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.
Priority 3 (P3)—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.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or
configuration. There is little or no effect on your business operations.
