Preparing the EPLD Images for Installation
Before you can update the EPLD images for each of your switch modules, you must determine the Cisco
NX-OS version that your switch is using, make sure that there is space for the new EPLD images, and
download the images.

Before you upgrade any EPLD images, be sure that you have updated the Cisco NX-OS operating
system to the level required for the images and be sure that you have one of the following EPLD
image files:
–
n7000-s1-epld.6.2.2.img (for Cisco Nexus 7004, 7009, 7010, and 7018 switches with
Supervisor 1 modules)
–
n7000-s2-epld.6.2.2.img (for Cisco Nexus 7004, 7009, 7010, and 7018 switches with
Supervisor 2 or Supervisor 2E modules)
n7700-s2-epld.6.2.2.img (for Cisco Nexus 7710 and 7718 switches)
–
EPLD and software images for a chassis with Supervisor 1 modules include "s1" in the image
name and images for Supervisor 2 and Supervisor 2E have "s2" in the image name.
You can execute an upgrade from the active supervisor module only. This upgrade is for one or all
of the modules as follows:
You can upgrade a module individually.
–
You can upgrade all modules sequentially.
–
You can upgrade all modules in parallel.
–
You can update the images for one or all modules whether the switch is online or offline as follows:
–
If the modules are online, only the EPLD images with version numbers that differ from the new
EPLD images are upgraded.
If the modules are offline, 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 (the supervisor
switchover is not disruptive to traffic on Cisco Nexus 7000 Series switches). On a switch that has
only one supervisor module, you can upgrade the active supervisor, but this will disrupt 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.
