Server is unresponsive (cannot press F1 to 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 to 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.
