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.
Extend the server from the rack
WARNING: To reduce the risk of personal injury or equipment damage, be sure that the rack is
adequately stabilized before extending a component from the rack.
WARNING: To reduce the risk of personal injury, be careful when pressing the server rail-release
latches and sliding the server into the rack. The sliding rails could pinch your fingers.
To extend the server from the rack:
1. Pull down the quick-release levers on each side of the server to release the server from the rack.
