Updating the server configuration

When you turn on the server for the first time after you add or remove a device,
you might receive a message saying that the configuration has been changed. The
Setup Utility program starts automatically so that you can save the new
configuration settings. For more information, see Chapter 6, "Configuring the
server," on page 71.
Some optional devices have device drivers that you must install. For information
about installing device drivers, see the documentation that comes with each device.
The server comes with at least one microprocessor. If more than one
microprocessor is installed, the server can operate as a symmetric multiprocessing
(SMP) server. You might have to upgrade the operating system to support SMP.
For more information, see the operating-system documentation.
If the server has an optional RAID controller and you have installed or removed a
hard disk drive, see the documentation that comes with the RAID controller for
information about reconfiguring the disk arrays.

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.
