2 Release Notes for Catalyst 4500 Series Software Release 8.x OL-4502-02 ROMMON Requirements If the Boot ROM (ROMMON) loaded onto your switch is version 4.5(1) or earlier, you need to upgrade the ROMMON to at least version 5.4(1) in order to run software release 8.1 or later. Upgrading the ROMMON Follow these guidelines to upgrade the ROMMON on your switch: 3 Release Notes for Catalyst 4500 Series Software Release 8.x OL-4502-02 System Requirements Caution To avoid actions that might make your system unbootable, read this entire section before starting the upgrade. You can do this procedure entirely over a Telnet connection, but if something fails, you will need to have access to the console serial port. If done improperly, the system can become unbootable. You will then have to return it to Cisco for repair. This section describes an upgrade to ROMMON version 6.4(1). The same procedure applies to other ROMMON versions, but you will have to substitute appropriate version numbers in the upgrade image names. Step 1 Download the promupgrade program from Cisco.com and place it on a TFTP server in a directory that is accessible from the switch to be upgraded. The promupgrade programs are available at the same location on Cisco.com where you download Catalyst 4500 series system images. To upgrade to ROMMON version 6.1(4), download the cat4000-promupgrade.6-1-4.bin file. Step 2 In privileged mode on your switch, use the show version command to verify the ROMMON version loaded on the switch. The ROMMON version number is listed as the System Bootstrap Version. For example, in the following output, the system is running ROMMON version 6.1(2): Console> (enable) show version WS-C4003 Software, Version NmpSW:5.5(8) Copyright (c) 1995-2001 by Cisco Systems, Inc.
