You can individually update each module that is online. The EPLD update is only disruptive to the
module being upgraded.
If you interrupt an upgrade, the module must be upgraded again.
The upgrade or downgrade can only be executed from the active supervisor module. While the active
supervisor module cannot be updated, you can update the other modules individually.
In Cisco MDS 9100 Series fabric switches, be sure to specify one (1) as the module number.
Cisco MDS 9200 Series switches do not support EPLD upgrades.
