Turning Off The Server - Lenovo TD200 - ThinkServer - 3809 Hardware Maintenance Manual

Note: When 4 GB or more of memory (physical or logical) is installed, some memory is reserved for various
system resources and is unavailable to the operating system. The amount of memory that is reserved for
system resources depends on the operating system, the configuration of the server, and the configured
peripheral component interconnect (PCI) options.

Turning off the server

When you turn off the server and leave it connected to ac power, the server can respond to requests to
the service processor, such as a remote request to turn on the server. While the server remains connected
to ac power, one or more fans might continue to run. To remove all power from the server, you must
disconnect it from the power source.
Some operating systems require an orderly shutdown before you turn off the server. See your
operating-system documentation for information about shutting down the operating system.
Statement 5
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

from the power source.
The server can be turned off in any of the following ways:

the server, if your operating system supports this feature.

system failure.
