power-control button becomes active, one or more fans might start running, 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 the server is connected to an Advanced System Management interconnect
network that contains at least one server with an optional Remote Supervisor
Adapter installed, the server can be turned on from the Remote Supervisor
Adapter user interface.
v If your operating system supports the systems-management software for an
optional Remote Supervisor Adapter, 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.
Chapter 1. General information 7
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 PCI options.
Turning off the server

Chapter 3. Installing options
This chapter provides detailed instructions for installing hardware options in the
server.
Installation guidelines
Before you begin installing options in the server, read the following information:
v For a list of supported options for the server, go to http://www.ibm.com/us/
compat/.
v Read the safety information beginning on page v and the guidelines in “Handling
static-sensitive devices” on page 12. This information will help you work safely
with the server and options.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v Yo u do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.
v When you need to access the inside of the server, you might find it easier to lay
the server on its side.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the left-side cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the left-side cover removed might damage server components.
v Yo u have followed the cabling instructions that come with optional adapters.
v Yo u have replaced a failed fan within 48 hours.
v Yo u have replaced a hot-swap drive within 2 minutes of removal.
v Yo u do not remove the air baffle while the server is running. Operating the server
without the air baffle might cause the microprocessor to overheat.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor and heat sink.
© Copyright IBM Corp. 2004, 2007 11
Working inside the server with the power on
The server supports hot-swap devices and is designed to operate safely while it is
turned on and the cover is removed. Follow these guidelines when you work inside
a server that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts
before working inside the server; do not wear cuff links while you are working
inside the server.
v Do not allow your necktie or scarf to hang inside the server.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall
into the server as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices, including the server.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
