AC power LED: On some server models, each hot-swap power supply has an ac
power LED and a dc power LED. During typical operation, both the ac and dc
power LEDs are lit. For any other combination of LEDs, see “Power-supply LED
errors” on page 98.
DC power LED: On some server models, each hot-swap power supply has a dc
power LED and an ac power LED. During typical operation, both the ac and dc
power LEDs are lit. For any other combination of LEDs, see “Power-supply LED
errors” on page 98.

Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except for the service processor is
shut down; however, the server can respond to requests from the service processor
(also called the baseboard management controller), such as a remote request to
turn on the server. The power-on LED flashes to indicate that the server is
connected to ac power but is not turned on.

Turning on the server
Approximately 5 seconds after the server is connected to ac power, the
power-control button becomes active, and you can turn on the server and start the
operating system by pressing the power-control button.
The server can also be turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If your operating system supports the systems-management software for an
optional Remote Supervisor Adapter II SlimLine, the systems-management
software can turn on the server.
v If your operating system supports the Wake on LAN feature, the Wake on LAN
feature can turn on the server.
Note:
When 4 GB or more of memory (physical or logical) is installed, some
memory is reserved for various system resources and might be 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 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 from the service processor, such as a remote request to turn
on the server. 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 cord. To remove all electrical current from the device, ensure
that all power cords are disconnected from the power source.

Chapter 2. Configuring the server
Detailed information about configuring the server is in the IBM xSeries User’s Guide
on the IBM Documentation CD.
The latest information about these programs and the most recent device-driver files
are available at http://www.ibm.com/pc/support.
The following configuration programs and capabilities come with the server:
v Configuration/Setup Utility
The Configuration/Setup Utility program is part of the basic input/output system
(BIOS) code in your server. Use it to configure serial port assignments, change
interrupt request (IRQ) settings, change the startup-device sequence, set the
date and time, and set passwords.
v IBM ServerGuide Setup and Installation CD
The ServerGuide program provides software-setup tools and installation tools
that are designed for your server. Use this CD during the installation of your
server to configure basic hardware features, such as an integrated SCSI
controller with RAID capabilities, and to simplify the installation of your operating
system.
v SCSISelect Utility program for Adaptec
®
HostRAID
™
configuration
Use the SCSI HostRAID feature of the SCSISelect Utility program to configure
the SCSI controller with integrated RAID and the devices that are attached to it.
v Ethernet controller configuration
