Major components of the xSeries 306 Type 8836 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 that you might have to perform before you
remove or install the component.

Chapter 2. Installing options
This chapter provides basic instructions for installing hardware options in your
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 in your server, read the following information:
v Read the safety information beginning on page v and the guidelines in “Handling
static-sensitive devices” on page 7. This information will help you work safely
with your server and options.
v Make sure that you have an adequate number of properly grounded electrical
outlets for your server, monitor, and other devices that you will connect to the
server.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v You do not need to turn off the server to install or replace 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 For a list of supported options for your server, go to
http://www.ibm.com/pc/compat/.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive tray 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.
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan within 48 hours.
v You do not remove the air baffle while the server is running. Operating the server
without the air baffle might cause the microprocessor to overheat.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices, including your server.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
© Copyright IBM Corp. 2004 7

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, place it back
into its static-protective package. Do not place the device on your 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.
Installing a memory module
The following notes describe the types of dual inline memory modules (DIMMs) that
your server supports and other information that you must consider when installing
DIMMs:
v Your server supports 256 MB, 512 MB, and 1 GB DIMMs, for a maximum of 4
GB of system memory. Go to the ServerProven list at
http://www.ibm/com/pc/compat for a list of memory modules you can use with
your server.
v The amount of usable memory will be reduced depending on the system
configuration. A certain amount of memory must be reserved for system
resources. The BIOS will display the total amount of installed memory and the
amount of configured memory.
v Your server comes with one 512 MB DIMM installed in DIMM connector 1. If your
system has one DIMM installed, when you install an additional DIMM, it must be
installed in DIMM connector 3, and must be the same size, speed, type, and
technology as the DIMM installed in DIMM connector 1. You can mix compatible
DIMMs from various manufacturers.
v If you install a second pair of DIMMs in DIMM connectors 2 and 4, they do not
have to be the same size, speed, type, and technology as the DIMMs installed in
DIMM connectors 1 and 3. However, the size, speed, type, and technology of the
DIMMs you install in DIMM connectors 2 and 4 must match each other.
v Install only 2.5 V, 184-pin, double-data-rate (DDR), PC2700 or PC3200,
unbuffered synchronous dynamic random-access memory (SDRAM) with error
correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest
PC2700 and PC3200 SDRAM unbuffered DIMM specification.
v When you restart the server, the system displays a message indicating that the
memory configuration has changed.
