EPLD Configuration
Installation Guidelines
You can upgrade (or downgrade) EPLDs using CLI commands on the Cisco Nexus 7000 Series device.
Follow these guidelines when you upgrade or downgrade EPLDs:
• You can execute an upgrade from the active supervisor module only. All the modules, including the
active supervisor module, can be updated individually.
• You can individually update each module whether it is online or offline as follows:
–
If you upgrade EPLD images on an online module, only the EPLD images with version numbers
that differ from the new EPLD images are upgraded.
–
If you upgrade EPLD images on an offline module, all of the EPLD images are upgraded.
• On a system that has two supervisor modules, upgrade the EPLDs for the standby supervisor and
then switch the active supervisor to the standby mode to upgrade its EPLDs. On a system that has
only one supervisor module, you can upgrade the active supervisor, but this will distrupt its
operations during the upgrade.
• If you interrupt an upgrade, you must upgrade the module that is being upgraded again.
• The upgrade process disrupts traffic on the targeted module.
• Do not insert or remove any modules while an EPLD upgrade is in progress.
