this problem by shutting down the server, waiting 3 minutes for the server to fully shutdown, and then
restarting the server, which prompts the Accelerator card to revert to its backup firmware.
Revert an Accelerator card to its backup firmware
Procedure overview
A firmware load failure on the Accelerator card can prevent the card from communicating with the
OmniCube or OmniStack server. You can try to correct this problem by reverting to the backup
firmware. Shutting down the server, waiting 3 minutes for the server to fully shutdown, and then
restarting the server, prompts the Accelerator card to fail and use its backup firmware. If both LEDs
on the Accelerator card are not glowing steady green or the server fails to return to normal operation,
