Installation Manual

Performing a hardware iLO reboot with the server UID button
When you initiate a hardware iLO reboot, the server hardware initiates the iLO reboot.
To initiate a hardware iLO reboot, press and hold the UID button for 10 seconds or longer.
The UID button/LED flashes blue 8 Hz/cycle per second to indicate that an iLO hardware reboot
is in progress.
CAUTION: Initiating a hardware iLO reboot does not make any configuration changes, but
ends all active connections to iLO. If a firmware flash is in progress, it is interrupted, which might
cause data corruption on the flash device. If data corruption occurs on the flash device, use the
recovery method described in “iLO network Failed Flash Recovery” (page 355).
Data loss or NVRAM corruption might occur during a hardware iLO reboot.
Do not initiate a hardware reboot if other troubleshooting options are available.
Reset iLO to the factory default settings
In some cases, you might need to reset iLO to the factory default settings. For example, you
must reset iLO to the default settings when you disable FIPS mode. You can use the iLO RBSU
or the UEFI system utilities to perform this task.
CAUTION: This operation clears all user and license data.
If a server has an installed iLO Advanced license when you perform this procedure, the iLO
Advanced icon might be selected when the server boot process finishes. The icon will be set
correctly after POST completes, or after the server is shut down, powered off, and then powered
on again.
