can add LAN interfaces.
v Power throttling
Each blade server is powered by two BladeCenter redundant power-supply
modules. By enforcing a power policy known as power domain oversubscription,
the BladeCenter unit can share the power load between two power modules to
ensure efficient power for each device in the BladeCenter unit. This policy is
enforced when the initial power is applied to the BladeCenter unit or when a
blade server is inserted into the BladeCenter unit. You can configure and monitor
the power environment by using the management module. For more information
about configuring and using power throttling, see the management-module
documentation, or go to http://www.ibm.com/bladecenter/ and click Support.
Reliability, availability, and serviceability features
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These RAS features help to ensure the integrity of the data
that is stored in the blade server, the availability of the blade server when you need
it, and the ease with which you can diagnose and correct problems.
The blade server has the following RAS features:
v Advanced Configuration and Power Interface (ACPI)
v Automatic error retry or recovery
v Automatic server restart
v Built-in monitoring for temperature, voltage, and hard disk drives
v Chipkill™ memory for x4 DIMMs

Major components of the blade server
The LS22 and LS42 blade servers have the same system board with components
installed in the same locations. The LS42 Type 7902 blade server models also have
an MPE with components that are similar to the blade server system board.
You must remove the blade server from the BladeCenter unit and remove the cover
to see the components. For the LS42 Type 7902 blade server, you must remove the
MPE unit to see the components on the blade server system board.
The following illustration shows the major components of the blade server.
The following illustration shows the major components of the MPE that is installed
on the LS42 Type 7902 blade server.

Chapter 2. Power, controls, and indicators
This chapter describes the power features, how to turn on and turn off the blade
server, and what the controls and indicators mean. This chapter also identifies the
system-board connectors.
Blade server control panel and LEDs
This section describes the controls and LEDs on the blade server.
Notes:
1. The control panel door is shown in the closed (normal) position in the following
illustration. To access the power-control button, you must open the control panel
door.
2. The following illustration shows a single-width type of blade server. The MPE
also interacts with the control panel on the blade server.
KVM select button: Press this button to associate the shared BladeCenter unit
keyboard, video, and mouse port (KVM) with the blade server. The LED on this
button flashes while the request is being processed and then is lit when the
ownership of the keyboard, video, and mouse has been transferred to the blade
server. It can take approximately 20 seconds to switch the keyboard, video, and
mouse control to the blade server.
Using a keyboard that is directly attached to the management-module, you can
press keyboard keys in the following sequence to switch KVM control between
blade servers:
NumLock NumLock bay_number Enter
Where bay_number is the two-digit number of the blade bay in which the blade
server is installed. A blade server that occupies more than one blade bay is
identified by the lowest bay number that it occupies.
© Copyright IBM Corp. 2008, 11
If there is no response when you press the KVM select button, you can use the
management-module Web interface to determine whether local control has been
disabled on the blade server.
Notes:
1. The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard and mouse, even if the
keyboard and mouse have PS/2-style connectors.
2. If you install a supported Microsoft Windows operating system on the blade
server while it is not the current owner of the KVM, a delay of up to 1 minute
occurs the first time that you switch the KVM to the blade server. During this
one-time-only delay, the blade server device manager enumerates the
keyboard, video, and mouse and loads the device drivers. All subsequent
switching happens in the normal KVM switching time frame (up to 20 seconds).
Media-tray
select button: Press this button to associate the shared BladeCenter
unit media tray (removable-media drives and front-panel USB ports) with the blade
server. The LED on the button flashes while the request is being processed, and
then is lit when the ownership of the media tray has been transferred to the blade
server. It can take approximately 20 seconds for the operating system in the blade
server to recognize the media tray.
If there is no response when you press the media-tray select button, you can use
the management-module Web interface to determine whether local control has been
disabled on the blade server.
Note: The operating system in the blade server must provide USB support for the
blade server to recognize and use the removable-media drives and front-panel USB
ports.
Activity LED: When this green LED is lit, it indicates that there is activity on the
hard disk drive or network.
Location LED: The system administrator can remotely light this blue LED to aid in
visually locating the blade server. When this LED is lit, the location LED on the
BladeCenter unit is lit also. The location LED can be turned off through the
management-module Web interface or through IBM Director Console.
Information LED: When this amber LED is lit, it indicates that information about a
system error for the blade server has been placed in the management-module
event log. The information LED can be turned off through the management-module
Web interface or through IBM Director Console.
Blade-error LED: When this amber LED is lit, it indicates that a system error has
occurred in the blade server. The blade-error LED will turn off only after the error is
corrected.
Power-on LED: This green LED indicates the power status of the blade server in
the following manner:
v Flashing rapidly: The service processor (BMC) on the blade server is
communicating with the management module.
v Flashing slowly: The blade server has power but is not turned on.
v Lit continuously: The blade server has power and is turned on.
12 BladeCenter LS22 and LS42 Type 7901 and 7902: Installation and User’s Guide
Power-control button: This button is behind the control panel door. Press this
button to turn on or turn off the blade server.
Note: The power-control button has effect only if local power control is enabled for
the blade server. Local power control is enabled and disabled through the
management-module Web interface.
Turning on the blade server
After you connect the blade server to power through the BladeCenter unit, the blade
server can start in any of the following ways:
v You can press the power-control button on the front of the blade server (behind
the control panel door, see “Blade server control panel and LEDs” on page 11 ) to
start the blade server.
Notes:
1. Wait until the power-on LED on the blade server flashes slowly before you
press the power-control button. While the service processor in the
management module is initializing, the power-on LED does not flash, and the
power-control button on the blade server does not respond.
2. While the blade server is starting, the power-on LED on the front of the blade
server is lit. See “Blade server control panel and LEDs” on page 11 for the
power-on LED states.
If a power failure occurs, the BladeCenter unit and then the blade server can
v
start automatically when power is restored, if the blade server is configured
through the management module to do so.
v You can turn on the blade server remotely by using the management module.
v If the blade server is connected to power (the power-on LED is flashing slowly)
and the Wake on LAN feature has not been disabled through the management
module, the Wake on LAN feature can turn on the blade server.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the
BladeCenter unit. The blade server can respond to requests from the service
processor, such as a remote request to turn on the blade server. To remove all
power from the blade server, you must remove it from the BladeCenter unit.
Shut down the operating system before you turn off the blade server. See the
operating-system documentation for information about shutting down the operating
system.
The blade server can be turned off in any of the following ways:
v You can press the power-control button on the blade server (behind the control
panel door, see “Blade server control panel and LEDs” on page 11). This starts
an orderly shutdown of the operating system, if this feature is supported by the
operating system.
Note: After you turn off the blade server, wait at least 5 seconds before you
press the power-control button to turn on the blade server again.
v If the operating system stops functioning, you can press and hold the
power-control button for more than 4 seconds to turn off the blade server.
Chapter 2. Power, controls, and indicators 13
v The management module can turn off the blade server.
– If the system is not operating correctly, the management module will
automatically turn off the blade server.
– Through the management-module Web interface, you can also configure the
management module to turn off the blade server. For additional information,
see the IBM BladeCenter Management Module User’s Guide.

Chapter 3. Installing optional devices
This chapter provides instructions for installing optional hardware devices in the
blade server. Instructions for removing some optional devices are provided in case
you have to remove one option to install another.
Installation guidelines
Before you install optional devices, read the following information:
v Read the safety information that begins on page “Safety” on page v and the
guidelines in “Handling static-sensitive devices” on page 18. This information will
help you work safely.
v When you install your new blade server, take the opportunity to download and
apply the most recent firmware updates. This step will help to make sure that any
known issues are addressed and that your blade server is ready to function at
maximum levels of performance. To download firmware updates for your blade
server:
Note: Changes are made periodically to the IBM Web site. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www.ibm.com/bladecenter/.
2. Click Support.
3. Under Support information, click Product support and information.
4. Under Popular links, click Publications lookup.
5. From the Product family menu, select Bladecenter LS22 or BladeCenter
LS42 and click Go.
Download and install the latest firmware for the management module installed in
your BladeCenter unit (see the documentation for your management module).
v Observe good housekeeping in the area where you are working. Put removed
covers and other parts in a safe place.
v Back up all important data before you make changes to disk drives.
v Before you remove a hot-swap blade server from the BladeCenter unit, you must
shut down the operating system and turn off the blade server. You do not have to
shut down the BladeCenter unit itself.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the blade server, or open or close a latch.
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 you can remove or
install the component while the BladeCenter unit 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 are finished working on the blade server, reinstall all safety shields,
guards, labels, and ground wires.
