Upgrading the Nonsupervisor Engine Module EPLD Images
Caution Do not power off or reset the switch or module during the upgrade process. Powering off or resetting the
switch or module could leave the module in an unusable state.
Note Before you begin the procedures in this chapter, make sure that you have downloaded the new EPLD
upgrade image to the supervisor engine flash memory (bootflash: or slot0:).
You can upgrade the nonsupervisor engine module EPLD image by using the download command with
the epld keyword. If you enter the download epld file command without specifying a module, the new
EPLD image is downloaded to all compatible modules where the new EPLD image version is greater
than the existing version on the module. If you use the download epld file mod command with the force
keyword, the existing EPLD image on a module is upgraded with the new EPLD image regardless of the
existing version level.
To upgrade the EPLD on the nonsupervisor engine modules (switching modules and service modules),
perform this task in privileged mode:
Task Command
Step 1
Upgrade the nonsupervisor engine EPLD image. download epld file
download epld file mod [force]
Step 2
