iv BladeCenter S Types 7779 and 8886: Power Modules
Chapter 1. BladeCenter S chassis power modules
A minimum of two power modules must be installed in power module bays 1 and
2 on the rear of the BladeCenter S chassis. Additional power modules, if installed,
are installed in power module bays 3 and 4.

Power modules
The BladeCenter S system supports up to four autoranging power modules that
are capable of supporting either 110 V ac or 220 V ac.

Power module
There are two types of power modules. These power modules are identical except
for the power cord connector; one power module has a C14 connector and the
other power module has a C20 connector. Both types of power modules can be
installed in the same chassis.

Within the BladeCenter S chassis, all power supplies are combined into a single
power domain, which distributes power to each of the blade servers and modules
through the system midplane.
2 BladeCenter S Types 7779 and 8886: Power Modules
You must install a minimum of two power modules. If you install only two power
modules, install them in power module bays 1 and 2 (the top and bottom power
module bays on the right as you face the rear of the BladeCenter S chassis).
Note: You must install all four power modules if you are using both disk storage
modules.
If you disengage or remove all devices from the front of the BladeCenter S chassis
(media tray, blade servers, and disk storage modules), the power modules will be
disabled.
Indicators and controls
There are three LEDs on each power module:
AC power
Lit (green). Power is being supplied to the power module.
DC power
Lit (green). Power is being supplied from the power module to the
BladeCenter S chassis midplane.
Fault Lit (amber). There is a fault with the power module.
Note: Before unplugging the AC power cord from the power module or
removing the power module from the BladeCenter S chassis, verify that the
capacity of the remaining power modules are sufficient to meet the
minimum power requirements for all components in the BladeCenter S
chassis. You can view power status and requirements through the
advanced management module.
For information on accessing and using the advanced management
module, see the Advanced Management Module User's Guide.
1. Verify that the power modules are properly connected to an AC power
source. All power modules in the BladeCenter S chassis must be
connected to the same power input voltage (either 110 V ac or 220 V
ac). Do not mix power input voltages.
2. Unplug the AC power cord from the power module and plug it in
again.
3. Reseat the power supply.
4. Swap the AC power cord with a power cord that is known to be
working.
5. Move the power module to another power module bay in the
BladeCenter S chassis.

Chapter 2. Installation guidelines
Before you remove or replace a component, read the following information.
v Read Safety and “Handling static-sensitive devices” on page 6. This information
will help you work safely.
v Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v You do not have to disconnect the BladeCenter S system from power to install or
replace any of the hot-swap modules. You must shut down the operating system
and turn off a hot-swap blade server before you remove it, but you do not have
to remove power from the BladeCenter S system itself.
v Do not attempt to lift an object that you think is too heavy for you. If you have
to lift a heavy object, observe the following precautions:
– Make sure that you stand safely without slipping.
– Distribute the weight of the object equally between your feet.
– Use a slow lifting force. Never move suddenly or twist when you lift a heavy
object.
– To avoid straining the muscles in your back, lift by standing or by pushing
up with your leg muscles.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the BladeCenter S system.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v Orange on a component or an orange label on or near a component indicates
that the component may be hot-swapped, which means that you can remove or
install the component while the BladeCenter S system 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 Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the BladeCenter S chassis, open or close a latch,
and so on.
System reliability guidelines
To help ensure proper system cooling and system reliability, make sure the
following requirements are met.
v Each of the module bays on the front and rear of the BladeCenter S chassis has
either a module or a module bay filler installed in it.
v Each of the blade bays on the front of the BladeCenter S chassis has either a
blade server or a blade bay filler installed in it.
v Each of the disk storage module bays has a disk storage module or disk storage
module filler installed in it. If a disk storage module is installed, each of the
drive bays has a hard disk drive or a hard disk drive bay filler installed in it.
v Each of the drive bays in a blade server storage expansion option has either a
hot-swap drive or a filler panel installed.
v You have followed the cabling instructions that come with optional adapters.

v Cables for the optional modules are routed correctly.
v A failed fan module is replaced as soon as possible.
Handling static-sensitive devices
Make sure that you read these guidelines before handing static-sensitive devices.
Attention: Static electricity can damage the BladeCenter S chassis 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 electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v The use of a grounding system is recommended. For example, 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 BladeCenter S chassis or rack 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 immediately without setting
down the device. If it is necessary to set down the device, put it back into its
static-protective package.
v Take additional care when you handle devices during cold weather. Heating
reduces indoor humidity and increases static electricity.

Chapter 3. Installing a power module
You can install a power module while the BladeCenter S system is powered on. To
install it, open the release handle, slide the power module into the power module
bay, and close the release handle.
Notes:
v Make sure the power cord is not connected to the power module when installing
the power module in a BladeCenter S chassis.
v On the rear of the power module, there is a plastic strain-relief tie that should
not be removed.

Chapter 4. Removing a power module
You can remove a power module while the BladeCenter S system is powered on.
To remove it, open the release handle and slide the power module out of the
power module bay.
Attention:
v To maintain proper system cooling, do not operate the BladeCenter S system
without a power module or power module filler in each power module bay.
Install a power module or filler within one minute of the removal of a power
module.
v If you are removing a functioning power module, make sure that power LEDs
on the remaining power modules are lit and the power management policy you
have chosen supports the removal of the power module. If not, shut down the
operating systems and turn off all of the blade servers, before you proceed. (See
the documentation that comes with the blade server for instructions for shutting
down the blade server operating system and turning off the blade server.)
1. Disconnect the power cable.
2. Open the release handle (rotate the handle down).
3. Slide the power module out of the power module bay.
4. If you are instructed to return the power module, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to
you.
