• The compute node restarts automatically and attempts POST again.
• The compute node hangs and you must manually restart the compute node for the compute node to
attempt POST again.
After a specified number of consecutive attempts (automatic or manual), the Nx boot failure feature causes
the compute node to revert to the default UEFI configuration and start the Setup utility, so that you can make
the necessary corrections to the configuration and restart the compute node. If the compute node is unable to
successfully complete POST with the default configuration, there might be a problem with the system board.
To specify the number of consecutive restart attempts that will trigger the Nx boot failure feature in the
Setup utility, complete the following steps:
Step 1. Click System Settings .
Step 2. Click Recovery .
Step 3. Click Post Attempts .
The available options are 3, 6, 9 and Disable.
