Chapter 4. Turning on and turning off the server

This chapter provides information about turning on and turning off the server.

Turning on the server

The server can be turned on in one of the following ways:
• After you finish unpacking and setting up the server, connect it to an ac power source. Press the power
switch on the front of the chassis to turn on the server. The server needs about 30 seconds for the
ThinkServer Management Module (TMM, also known as BMC) to initialize whenever you connect the
server to an ac power source. If you press the power switch during this period, the server will not start
immediately; it will start after the TMM initialization finishes.
• When the Wake on LAN feature is enabled on the server that is connected to an ac power source and a
LAN, a network administrator can remotely turn on or wake up the server from a management console
using remote network management software.
• You also can use the related TMM feature to remotely turn on the server through the management LAN.
For more information about the TMM, refer to the ThinkServer Management Module User Guide, which is

Turning off the server

CAUTION:
The power control button on the device and the power switch on the power supply do not turn off
the electrical current supplied 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.
The server can be turned off in one of the following ways:
• Turn off the server from the operating system if your operating system supports this feature. After an
orderly shutdown of the operating system, the server will turn off automatically. For instructions on how
to shut down your specific operating system, refer to the related documentation or help system for
the operating system.
• Press the power switch on the front of the chassis to start an orderly shutdown of the operating system
and turn off the server, if your operating system supports this feature.
• If your server stops responding and you cannot turn it off, press and hold the power switch on the front
of the chassis for four seconds or more. If you still cannot turn off the server, disconnect all power
cords from the server.
• If the server is connected to a LAN, a network administrator can remotely turn off the server from a
management console using remote network management software.
• You also can use the related TMM feature to remotely turn off the server through the management LAN.
