About this task

Configuration changes, such as added devices or adapter firmware updates, and

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).
