Server is unresponsive (POST failed and cannot start System Setup)

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 server reverts to the default
UEFI configuration and starts System Setup 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 (system board assembly).
You can specify the number of consecutive restart attempts in System Setup. Restart the server and press
the key according to the on-screen instructions to display the LXPM system setup interface. (For more
information, see the "Startup" section in the LXPM documentation compatible with your server at

POST Attempts Limit. Available options are 3, 6, 9, and disable.
