ROM Monitor Download Procedures for
Cisco VG224 Voice Gateways
This document contains procedures for downloading ROM monitor (ROMMON) software image upgrades. When you attempt to upgrade Cisco IOS images to Cisco IOS Release 12.3(4)XD or later releases on Cisco VG224 voice gateways, you must first ensure that ROMMON image version 123-4r or a later image is installed on the router.
Caution Failure to upgrade the ROMMON image to version 123-4r 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 12.3(4)XD or later releases. If you have received a Cisco VG224 voice gateways with a Cisco IOS Release 12.3(4)XD 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 devices:
•Cisco IAD2430 integrated access device
•Cisco VG224 voice gateways
The Cisco IOS images available on Cisco IOS Release 12.3(4)XD and later releases require the use of the ROMMON image version 123-4r. Attempting to run Cisco IOS Release 12.3(4)XD 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 12.3(4)XD and later IOS releases on the
Cisco VG224 voice gateways, you must ensure that a 123-4r or later ROMMON image is downloaded from the Cisco.com website onto a TFTP server and then is loaded onto the router before running the new Cisco IOS images. These ROMMON images are backward compatible with all Cisco IOS images released for Cisco VG224 voice gateways.
Two procedures are provided for copying ROMMON images to Cisco VG224 voice gateways: copy tftp to the external compact flash 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 123-4r ROMMON image. As required for Cisco VG224 voice gateways, the ROMMON image string has a name specific to these routers with the version number appended: CIAD2430.srec.122-8r.T2. Later versions of ROMMON upgrade files will be named following a similar pattern.
Updating the ROMMON Image in EXEC Mode
To upgrade the ROMMON image from privileged EXEC, complete these steps:
Note In the event of a power outage, the ROM monitor download will not be successful.
Step 1 Check if you are running read-only ROMMON, or upgrade ROMMON, and your ROMMON version by entering the command show rom-monitor as shown in the following example:Router#> show rom-monitorReadOnly ROMMON version:System Bootstrap, Version 12.3(xx), RELEASE SOFTWARE (fc1)TAC Support:http://www.cisco.com/tacCopyright (c) 2003 by cisco Systems, Inc.Upgrade ROMMON version:System Bootstrap, Version 12.3(xx), RELEASE SOFTWARE (fc1)TAC Support:http://www.cisco.com/tacCopyright (c) 2003 by cisco Systems, Inc.Currently running ROMMON from Upgrade regionROMMON from Upgrade region is selected for next bootRouter#
Step 2 Download the ROMMON file from Cisco.com and place it on your TFTP server.
Step 3 Upgrade the new ROMMON image by entering the command upgrade rom-monitor, as shown in the following example:Router# upgrade rom-monitor file tftp://18.104.22.168/C2400_RM2.123-4r.XD.srecLoading C2400_RM2.123-4r.XD.srec from 22.214.171.124 (via FastEthernet0/0):!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!![OK - 641719/1283072 bytes]This command will reload the router.

Opening a TAC Case
Using the online TAC Case Open Tool 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. The online TAC Case Open Tool is located at this URL:
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.

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.
