Nx-boot failure

Use this information for Nx-boot failure.

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).
