Chapter 7 Managing the Switch Hardware
Configuring EPLDs
Note To list the EPLDs running on your switch, use the show version module module_number epld
command. If any of the versions that you list are older than what is listed in Table 7-11, we recommend
that you update the EPLDs.
Determining Whether to Upgrade EPLD Images
As shown in Table 7-12, you can use various show commands to determine whether the EPLDs can be
upgraded for all the modules or for specific modules on a switch. These commands indicate the current
EPLD images, new EPLD images, and whether the upgrades would be disruptive to switch operations.

management server.
