Using the Server Health Summary

You can use iLO to display the Server Health Summary on an external monitor when the server is
powered on or off. This feature is useful for troubleshooting when the server will not start up, and can also
be used to view the server IP address and other health information.
Prerequisites
• The server has a UID button.
• An external monitor is connected.
Procedure
1. Press the UID button on the server.
CAUTION:
Press and release the UID button. Holding it down at any time for more than 5 seconds initiates
a graceful iLO reboot or a hardware iLO reboot. Data loss or NVRAM corruption might occur
during a hardware iLO reboot.
The Server Health Summary screen is displayed on the external monitor.
