Step 4 If there is not at least 120 MB of memory free for the EPLD files, delete some unneeded files, such as
earlier images, so there is enough free memory.
switch# delete bootflash:n7000-s1-kickstart.4.0.1.bin
switch# attach module 5
switch(standby)#
Step 5 Copy the EPLD image file from the FTP or management server to the bootflash or slot0 memory in the
active supervisor module. The following example shows how to copy from the FTP server to the
bootflash memory.
switch# copy ftp://10.1.7.2/n7000-s1-epld.4.0.2.img bootflash:n7000-s1-epld.4.0.2.img
Copy the EPLD image to the standby supervisor.
switch# copy bootflash:n7000-s1-epld.4.0.2.img
bootflash://sup-standby/n7000-s1-epld.4.0.2.img
You are ready to upgrade the EPLD images (see the “Upgrading EPLD Images” section on page 6-31).
Upgrading EPLD Images
When you start upgrading the EPLD images for a module, the Cisco NX-OS software tries to list the
current and new versions for each EPLD. If the module is installed and online, the software reports both
the installed and new versions of each EPLD, and where there is a difference, the software will upgrade
(or downgrade) to the new version when you confirm that the upgrade should occur. For a module that
is installed but offline, the software cannot determine the installed versions of its EPLDs so it upgrades
all of the EPLDs for that module when you confirm the upgrade. For a module that is not installed, the
software displays an error message and does not upgrade the EPLDs.
Example 12 shows how the software reports the current and new EPLD versions for a module that does
not need EPLD upgrades. The current and new version numbers for each EPLD are the same.
