Removal and replacement procedures 11
Powering 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.
3. If the server is installed in a rack, press the UID LED button on the front panel. Blue LEDs illuminate on
the front and rear panels of the server.
4. 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.
5. If the server is installed in a rack, locate the server by identifying the illuminated rear UID LED button.
6. Disconnect the power cords.
The system is now without power.
Extending the server from the rack
NOTE: If the optional cable management arm option is installed, you can extend the server without
powering down the server or disconnecting peripheral cables and power cords. These steps are only
necessary with the standard cable management solution.
1. Power down the server ("Powering down the server" on page 11).
2. Disconnect all peripheral cables and power cords from the server rear panel.
3. Loosen the thumbscrews that secure the server faceplate to the front of the rack.
4. Extend the server on the rack rails until the server rail-release latches engage.
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.
5. After performing the installation or maintenance procedure, slide the server back into the rack:
