Server power features
This section contains information on how to properly turn your server on and off.
Turning on the server
You can turn on the server in any of the fo llowing ways:
• If the power cords are connected to a pow er sour ce, y o u can press the po we r-control button on the front of the server.
Notes:
1. You can install a circular disk over the power-control button to prevent acci-
dental manual power-o ff. This disk, known as the po w er-contr ol b u tton shie ld,
comes with your server.
2. After you plug the power cords of your server into the electrical outlets, wait
approximately 20 seconds before pressing the power-control button. During
this time, the system-management adapter is initializing; therefore, the pow ercontrol button does not respond.
• If the server is turned on and a power failure occurs, the server will restart automatically when power is restored.
• If ac power is present a nd the server is in Standb y mode, the server can be turned
on from the Remote Supervisor Adapter user interface.
• When you plug in yo ur server for the first time, Wake on LAN
server.
• If your server was previously turned on, it must be properly placed in Standby
mode for the Wake on LAN feature to turn on the server.

can turn on the
Complete the following steps to manually turn on the server:
1. Review the information in “Safety” on page v.
2. Turn on all external devices, such as the monitor.
3. Plug the server power cords into the power source.
4. Press the power-control button on the front of the server.
Note: While the server is powering up, the power-on LED on the front of the
server is lit.
6 xSeries 440:Troubleshooting Guide
Turning off the server
Complete the following steps to manually turn off the server:
1. Review the information in “Safety” on page v.
2. See your operat ing system documentation for the proper procedure to shut down
the operating system.
Statement 5:
CAUTION:
The power control button on the device and the power swit ch on the power
supply do not turn off the electrical current supplie d to the device. The
device also might have more than one power cord. To remove all electrical
current from the device, ensure that all power cords are disconnected from
the power source.

3. Press the power-contr ol butt on on the front of the server. This will put the server in
Standby mode.
Note: You might need to press and hold the power-control button for more than 4
seconds to cause an immediate shutdo wn of the serve r a nd to force it into
Standby mode. You can use this feature if the operating system stops functioning.
4. Disconnect the server from the pow er source.
Note: After disconnecting all the po wer cords , w ait appr o xima tely 15 seconds for
your system to stop running. Watch for the power-on LED on the front of
the server to stop flashing.
Chapter 1. Introduction 7
Standby mode
Standby mode ref e rs to the co ndit io n in which the se rver is conn ected to an ac power
source but the server operating system is not running and all core logic is shut down
except for the service processor. In Standby mode, the server can respond to service
processor requests, such as a remote request to turn on the server. When the server
is in Standby mode, the power-on LED on the front of the server flashes (when the
server is running, the power-on LED stays on and does not flash).
You can put the server in Standby mode in any of the following ways:
• You can press the power-control button on the server. This starts an orderly shutdown of the operating system, if this feature is supported by your operating system.
• The server can be placed in Standby mode from the Remote Supervisor Adapter
user interface.
Complete the following steps to put the server into Standby mode:
1. See the operating system documentation for the proper procedure to shut down
the operating system.
Note: Each operating system is d ifferent. Read all the documentat ion about shut-
ting down the operating system before continuing.
2. Press the power-control button on the front of the server.
Notes:
a. After you place the server in Standby mode, wait at least 5 seconds before
you turn on the server again.
b. You might need to press and hold the power-control button for more than 4
seconds to cause an immediate shutdown of the operatin g sys tem an d to
force it into Standby mode. You can use this feature if the operating system
stops functioning.
