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. Shut down the OS as directed by the OS documentation.
2. Press the Power On/Standby button to place the server in standby mode.
When the server enters standby power mode, the system power LED changes
to amber.
3. Disconnect the power cords.
The system is now without power.
Removing the server from the rack
If the server is installed with an optional rack enabling kit, remove the server
from the rack before beginning any service procedures.
1. Power down the server ("Powering down the server" on page 15
).
