Last Updated:

Applies to

  • Cisco Nexus 3232C
  • Cisco Nexus 92300YC
  • Cisco Nexus 9336C-FX2


While updating the EPLD image on the switch models in the "applies to" section, the IO FPGA EPLD device shows as the device is programming the upgrade; however, post reboot the device does not show the updated version:

switch1# install epld bootflash:n9000-epld.9.3.4.img module 1
Compatibility check:
Module Type Upgradable Impact Reason
------ ----------------- ---------- ---------- ------
 1 SUP Yes disruptive Module Upgradable
Retrieving EPLD versions.... Please wait.
Images will be upgraded according to following table:

Module  Type   EPLD             Running-Version   New-Version  Upg-Required
------  ----  -------------     ---------------   -----------  ------------
     1   SUP  MI FPGA                   0x9        0x12            Yes
     1   SUP  IO FPGA                   0x9        0x12            Yes

The above modules require upgrade.
The switch will be reloaded at the end of the upgrade
