and ISO 7779 and are reported in
accordance with ISO 9296. Actual
sound-pressure levels in a given
location might exceed the average
values stated because of room
reflections and other nearby noise
sources. The declared sound-power
levels indicate an upper limit, below
which a large number of computers
will operate.
4 IBM xSeries 336 Type 8837: Installation Guide

Major components of the xSeries 336 Type 8837 server
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.
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 before you remove or install the
component.
The following illustration shows the major components in the server.

Chapter 2. Installing options
This chapter provides basic instructions for installing hardware options in the server.
These instructions are intended for users who are experienced with setting up IBM
server hardware. If you need more detailed instructions, see the Option Installation
Guide on the IBM xSeries Documentation CD.
Installation guidelines
Before you begin installing options, read the following information:
v Read the safety information beginning on page v and the guidelines in “Handling
static-sensitive devices” on page 8. 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 You do not have to turn off the server to install or replace hot-swap power
supplies or hot-swap fans.
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. Hot-swap 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 For a list of supported options for the server, go to
http://www.ibm.com/pc/compat/.
System reliability guidelines
To help make sure that the server has proper cooling and system reliability, make
sure that you perform the following actions:
v Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v If the server has redundant power, each of the power-supply bays has a power
supply 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 server cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the server cover removed might damage server components.
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan within 48 hours.
v When replacing a hot plug fan, you have 5 minutes to install the new fan or the
server will shutdown.
v You have replaced a hot-swap drive within 2 minutes of removal.

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 the server and other electronic devices.
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 Wear an electrostatic-discharge wrist strap, if one is available.
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.
Removing the server cover
This section provides an overview of the procedure for removing the server cover.
