Power down the server
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, remove
the power cord to remove power from the server. The front panel Power On/Standby button does
not completely shut off system power. Portions of the power supply and some internal circuitry
remain active until AC power is removed.
IMPORTANT: If installing a hot-plug device, it is not necessary to power down the server.
1. Back up the server data.
2. Shut down the operating system as directed by the operating system documentation.
NOTE: If the operating system automatically places the server in Standby mode, omit the next step.
3. Press the Power On/Standby button to place the server in Standby mode. When the server activates
Standby power mode, the system power LED changes to amber.
IMPORTANT: Pressing the UID button illuminates the blue UID LEDs on the front and rear panels. In a rack
environment, this feature facilitates locating a server when moving between the front and rear of the
rack.
4. Disconnect the power cords.
The system is now without power.
