Configuration changes, such as added devices or adapter firmware updates, and firmware or application
code problems can cause the server to fail POST (the power-on self-test). If this occurs, the server responds
in either of the following ways:
• The server restarts automatically and attempts POST again.
• The server hangs, and you must manually restart the server for the server to attempt POST again.
After a specified number of consecutive attempts (automatic or manual), the Nx-boot failure feature causes
the server 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 server. If the server 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, click
System Settings
➙
Recovery
➙
POST Attempts
➙
POST Attempts Limit
. The available
options are 3, 6, 9, and 255 (disable Nx-boot failure).
