Upgrading CPLDs
To ensure a successful CPLD upgrade, follow these guidelines:
• In IRF mode, the CPLD upgrade file for a subordinate switch must be saved on its active MPU, and
the CPLD upgrade file for the master switch can be saved on its active or standby MPU.
• Make sure no one performs any of the following operations during the upgrade:
{
Perform an active/standby switchover.
{
Power off or reboot the switch.
{
Reboot or swap the active MPU.
When the upgrade is complete, the card automatically reboots to validate the upgraded CPLD.
If you install an interface card during a CPLD upgrade, the system can supply power to the card only after
the upgrade is complete.
To upgrade a CPLD on an interface card or MPU:
