Powering Down The Server - HP 195294-001 - ProLiant - ML370R Setup And Installation Manual

Powering Down the Server

If you are adding hardware options to a new server that has not been installed in a
rack or work area, install all hardware options before installing and powering up the
server.
If the server is already installed, you must power down the system before adding
non-hot-plug hardware options.
IMPORTANT: Before upgrading components, back up the server data.
To power down the server:
1. Shut down the operating system as directed by the operating system. This
measure enables you to retain system power for use in performing diagnostic or
troubleshooting operations.
2. For servers deployed in a rack configuration, press the unit identification
(UID) switch on the server front panel to illuminate the blue front and rear UID
LEDs.
3. The UID LED remains blue as long as power is connected to the server and until
you press the UID switch again. Use this LED to identify a particular server
within a multi-server rack configuration.
