ROM Monitor Download Procedures for Cisco 2691, Cisco, 3631, Cisco 3725, and Cisco 3745 Routers
This document contains procedures for downloading ROM Monitor (ROMMON) software image upgrades. When you attempt to upgrade Cisco IOS images to Cisco IOS Release 12.2(13)T or later releases on Cisco 2691, Cisco 3631, Cisco 3725, and Cisco 3745 routers, you must first ensure that ROMMON image version 12.2(8r)T2 or a later image is installed on the router.
Caution Failure to upgrade the ROMMON image to version 12.2(8r)T2 or a later image before upgrading the Cisco IOS image causes the router to operate improperly and enter into an unrecoverable state.
This ROMMON image upgrade is required only if you are upgrading Cisco IOS images to Cisco IOS Release 12.2(13)T or later releases. If you have received a Cisco 2691, Cisco 3631, Cisco 3725, or
Cisco 3745 router with a Cisco IOS Release 12.2(13)T or later image already installed, you do not need to upgrade the ROMMON image.
This document contains the following sections:
ROMMON image upgrades are supported on the following routers:
The Cisco IOS images available on Cisco IOS Release 12.2(13)T and later releases require the use of the ROMMON image version 12.2(8r)T2. Attempting to run Cisco IOS Release 12.2(13)T or later
Cisco IOS releases without first ensuring that a newer ROMMON image is installed causes the router to operate improperly and enter into an unrecoverable state. To prevent this from occurring, and to ensure a smooth transition to Cisco IOS Release 12.2(13)T and later IOS releases on the Cisco 2691,
Cisco 3631, Cisco 3725, and Cisco 3745 routers, you must ensure that a 12.2(8r)T2 or later ROMMON image is downloaded from the Cisco.com website onto a TFTP server, and then loaded onto the router before running the new Cisco IOS images. These ROMMON images are backward compatible with all Cisco IOS images released for the Cisco 2691, Cisco 3631, Cisco 3725, or Cisco 3745 routers.
Two procedures are provided for copying ROMMON images to the Cisco 2691, Cisco 3631, Cisco 3725, and Cisco 3745 routers: copy tftp to the internal or external flash memory using the upgrade command, and another, using the upgrade command with the tftp path in the file url argument. You may use either procedure. The examples below use the 12.2(8r)T2 ROMMON image. As required for Cisco 2691, Cisco 3631, Cisco 3725, and Cisco 3745 routers, the ROMMON image string has a name specific to these routers with the version number appended: C2691_RM2.srec.122-8r.T2, C3631_RM2.srec.122-8r.T2, C3725_RM2.srec.122-8r.T2, C3745_RM2.srec.122-8r.T2. Later versions of ROMMON upgrade files will be named following a similar pattern.
Updating the ROMMON Image in EXEC Mode
Note The commands show rom-monitor, showmon, upgrade rom-monitor, upgrade rom-monitor preference, rommon-pref are present in the Cisco 3700 series routers only.
Complete these steps to upgrade the ROMMON image from EXEC mode:
Note In the event of a power outage, the ROM monitor download will not be successful.
Step 1 Download the ROMMON file from Cisco.com and place it on your TFTP server.
Step 2 Upgrade the current configuration by entering the command upgrade rom-monitor as shown in the following example:Router# upgrade rom-monitor file tftp://22.214.171.124/C3745_RM2.srec.122-8r.T2Loading C3745_RM2.srec.122-8r.T2 from 126.96.36.199 (via FastEthernet0/0):!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 641719/1283072 bytes]This command will reload the router. Continue? [yes/no]:y
Step 3 Press Enter to continue. The router begins downloading the ROMMON image.

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—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.
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.
