Configuring EPLDs
Installation Guidelines
You can upgrade (or downgrade) EPLDs using CLI commands on the Cisco Nexus 7000 Series switch.
Follow these guidelines when you upgrade or downgrade EPLDs:
•
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.
•
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 (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.
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.
To prepare the EPLD images for installation, follow these steps:
Step 1
Log in to the switch through the console port, an SSH session, or a Telnet session.
Step 2
Verify that the switch is using the expected version of the Cisco NX-OS operating system. The kickstart
and system lines indicate the Cisco NX-OS version. This step determines the versions of EPLD images
that you must download.

Step 3
Verify that you have 120 MB of free space on the active or standby supervisor memory devices for the
EPLD images that you will be downloading by using the
dir bootflash:
or
dir slot0:
commands.
