EPLD Configuration
To confirm the EPLD upgrade, see the “Displaying EPLD Versions for an I/O or Supervisor Module”
section on page 6-37.
Caution Resetting the power disrupts any data traffic going through the affected modules. If you power cycle the
entire system, all data traffic going through the system at the time of the power cycling is disrupted. This
is not necessary for release 4.0(3) or later.
Note As of release 4.0(3) or later, the system automatically loads the new power management EPLD after an
upgrade, so it is no longer necessary to reset the power for the module or system.
Upgrading EPLDs for the Active Supervisor Module
When you upgrade EPLDs on a system with only one supervisor module, data traffic on the device will
be affected when you reload the system after the upgrade. If you are upgrading EPLDs for a dual
supervisor system, you can upgrade the standby supervisor while the system is operational as explained
in the
“Upgrading the EPLD Images for I/O or Standby Supervisor Modules” section on page 6-32.
To upgrade EPLDs for the supervisor module in a system with a single supervisor module, follow these
steps:
Step 1 Determine the slot number for each module. The active supervisor is in either slot 5 or slot 6.
