Automated boot recovery (ABR)

While the server is starting, if the integrated management module detects problems
with the server firmware in the primary bank, the server automatically switches to
the backup firmware bank and gives you the opportunity to recover the firmware
in the primary bank. For instructions for recovering the UEFI firmware, see
"Recovering from a UEFI update failure or UEFI image corruption" on page 164.
After you have recovered the firmware in the primary bank, complete the
following steps:
1. Restart the server.
2. When the prompt press F3 to restore to primary is displayed, press F3 to

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 (power-on
self-test). If this occurs, the server responds in either of the following ways:
v The server restarts automatically and attempts POST again.
v The server hangs, and you must manually restart the server for the server to
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 in the Setup utility that will
trigger the Nx boot failure feature, complete the following steps. The available
values are 3, 6, 9, and 255 (disable Nx boot failure).
1. From the Setup utility main menu, select System Settings..
2. Next select Operating Modes.
