Upgrading IOS on a Cisco 6500 isn’t necessarily as simple as loading an IOS image and rebooting the switch.  There are several other items that should also be considered such as modules, firmware, and field programmable devices.  The firmware is the low level operating system beneath IOS that controls how the various components work and interact.

These are some items that might need to be upgraded in addition to the IOS:

Each of the above have their own firmware naming conventions and it can be difficult to find these files. Try to Google partial file names to locate the correct images on the Cisco site. Here are some tips for finding firmware:

  1. The CEF720 line card firmware starts with c2lc-rm2. As of this writing, 12.2(18r)S1 is the current version and the current file name is c2lc-rm2.srec.122-18r-S1
  2. The SUP720 firmware starts with c6ksup720. As of this writing, 8.5(4) is the current version and the current file name is c6ksup720-rm2-srec.8-5-4.srec.
