IBM BladeCenter Power Supply Modules
This option contains the warranty information, installation instructions, and the
following components for your IBM
®
BladeCenter
™
Power Supply Modules.
Attention: Nonredundant power is not supported in BladeCenter products. Power
modules must always be present in power bays 1 and 2. When any blade server or
option is in blade bay 7 through 14, power modules must be present in power bays
1 and 2, and power modules must be present in power bays 3 and 4.
If a power module fails or an ac power failure occurs, BladeCenter units configured
for redundant power operation will operate in a nonredundant mode, and the blower
modules will run at full speed. You must replace the failing power module or restore
ac power as soon as possible to regain redundant power operation and to reset the
blower modules to their normal operating speed.

Installation guidelines
Attention: If you are installing or replacing power modules, you must upgrade to
the latest level of management-module firmware. If two management modules are
installed in the BladeCenter unit, both management modules must be upgraded to
the same level of firmware. Go to the IBM Support Web site at
http://www.ibm.com/pc/support/ and obtain the latest firmware.
Before you begin to install power supply modules (also called power modules) in
your BladeCenter unit, read the following information:
v You do not need to disconnect the BladeCenter unit from power to install or
replace any of the hot-swap modules on the rear of the BladeCenter unit.
© Copyright IBM Corp. 2004 1

However, before you remove a blade server from the front of the BladeCenter
unit, you must shut down the operating system on that server and turn off the
blade server.
v Your BladeCenter unit is separated into two power domains. Power domain A
supports all the BladeCenter modules and blade servers 1 through 6; power
domain A uses power modules 1 and 2. Power domain B supports blade servers
7 through 14 and uses power modules 3 and 4. Power supplies installed in the
same power domain must be of the same wattage rating.
v For a list of supported options for your BladeCenter unit, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the module bays on the rear of the BladeCenter unit has either a module
or filler module installed.
v Each installed power modules must be connected to an ac power source. Do not
use a power module as a filler.
v A removed hot-swap module is replaced within 1 minute of removal.
v Cables for the option modules are routed according to the instructions in this
document.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your BladeCenter
chassis. To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
To reduce the possibility of 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 printed 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 BladeCenter chassis 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 BladeCenter
unit without setting the device down. If it is necessary to set down the device,
place it back into its static-protective package. Do not place the device on your
BladeCenter unit or on a metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
