Release Notes for Cisco 7600 Series Router Route Switch Processor 720 ROMMON

---

Current Release: 12.2(33r)SRE2
Past Releases: 12.2(33r)SRD6, 12.2(33r)SRB3, 12.2(33r)SRB4, 12.2(33r)SRC3

This document describes how to determine if you need to upgrade the ROM monitor (ROMMON) on your Cisco 7600 series router Route Switch Processor 720 (RSP720). It covers the following RSP720 models: RSP720-3C-GE, RSP720-3CXL-GE, RSP720-3C-10GE, and RSP720-3CXL-10GE. This document also provides the procedure to download the new ROMMON image from Cisco.com and then upgrade the ROMMON on your RSP720.

With this procedure, you can upgrade the ROMMON image similar to the way that you upgrade the operating system software (route switching processor software or MSFC Cisco IOS software). Without this procedure, you have to order the upgrade kit and physically replace the ROMMON (boot ROM).

Note The ROMMON software upgrade procedure in this publication applies only to RSP720-3C-GE and RSP720-3CXL-GE with ROMMON Software Release 12.2(33r)SRB3 and later releases, or the RSP720-3C-10GE and RSP720-3CXL-10GE with ROMMON Software Release 12.2(33r)SRC3 and later releases.

ROMMON Software Release 12.2(33r)SRE2 and later releases are supported in Cisco 7600 series systems that are running the following:

• Cisco IOS software on the RSP720 and on the MSFC4

Software Images

Table 1 lists the software releases for the Cisco 7600 series router ROMMON RSP720-3C-GE, RSP720-3CXL-GE, RSP720-3C-10GE, and RSP720-3CXL-10GE software.

ROMMON Image Overview

The RSP720-3C-GE, RSP720-3CXL-GE, RSP720-3C-10GE, and RSP720-3CXL-10GE ROMMONs consist of two modules:

• A resident module that is not changed during the upgrade procedure.
• An upgradable module that is updated during the upgrade procedure. This is the only module that you will download from Cisco.com.

Upgrading the RSP720 ROMMON Using Cisco IOS Commands

Before performing this procedure you need to download the new ROMMON image from Cisco.com. The download procedure is the same procedure that you use for downloading the route switching processor software images.

To download RSP720 ROMMON image from Cisco.com:

Step 1 To download Cisco 7600 Series Route Switch Processor 720 with 1 Gigabit Ethernet Uplinks, click:

http://www.cisco.com/cisco/software/type.html?mdfid=281997386&flowid=230

Cisco 7600 Series Route Switch Processor 720 with 10 Gigabit Ethernet Uplinks is available at:

http://www.cisco.com/cisco/software/type.html?mdfid=281939433&flowid=229

Step 2 Under Select a Software type, click IOS ROMMON Software.

Step 3 Under Select a Release, click on the required version number.

Step 4 Click Download Now.

To upgrade the ROMMON version on your RSP720-3C-GE, RSP720-3CXL-GE, RSP720-3C-10GE, or RSP720-3CXL-10GE using Cisco IOS commands, perform these steps:

Step 1 Check the active ROMMON information:

The display indicates that the active ROMMON is running in region1.

Step 2 Program the new ROMMON image to the Flash device on the RSP720:

Step 3 Check the new active ROMMON information:

Step 4 Reload the runtime image on the RSP720:

Caution Be sure to complete Step 5 before performing either or the following actions:
—An online insertion and removal (OIR) of the RSP720.

—A power cycling of the RSP720. The ROMMON upgrade might fail if you perform either of these actions before verifying that the runtime image successfully booted.

---

Step 5 After the system comes up, check the ROMMON information again:

The Region2 field should show “APPROVED, preferred.” The ROMMON stored in the Region2 is now the active ROMMON.

Storing More Than One ROMMON Image

The procedures in this section are optional and should be used only if you have multiple versions of the upgraded ROMMON image stored on the RSP720.

There are three regions (including the Gold region) where versions of the ROMMON image can be stored. You can use the upgrade rom-monitor slot preference and upgrade rom-monitor slot preference commands to switch between regions.

The ROMMON software upgrade feature allows you to have two upgraded ROMMON images (one in region F1, the second in region F2) in addition to the Gold ROMMON stored on the one-time programmable (OTP) EPROM section of the ROMMON. Use the upgrade rom-monitor slot preference command to select which ROMMON will be the preferred ROMMON the next time that the system is booted. You can change the preference as often as you like. The changes do not take effect until you reset the system.

To select a particular ROMMON image stored on the RSP720, perform this task:

Step 1 Change the ROMMON preference:

Step 2 Reload the route switching processor for the change to take effect:

Step 3 Verify the change:

You can also disqualify a specific region of ROMMON and use the other region or go back to using the Gold ROMMON stored in the OTP EPROM section by using the upgrade rom-monitor slot invalidate command.

To disqualify a specific ROMMON region, perform these steps:

Step 1 Disqualify a specific ROMMON region:

Step 2 Reload the route switching processor for the change to take effect:

Step 3 Verify the change:
