Guidelines for trained service technicians
This section contains information for trained service technicians.
Inspecting for unsafe conditions
Use the information in this section to help you identify potential unsafe conditions
in an IBM product on which you are working. Each IBM product, as it was
designed and manufactured, has required safety items to protect users and service
technicians from injury. The information in this section addresses only those items.
Use good judgment to identify potential unsafe conditions that might be caused by
non-IBM alterations or attachment of non-IBM features or optional devices that are
not addressed in this section. If you identify an unsafe condition, you must
determine how serious the hazard is and whether you must correct the problem
before you work on the product.
Consider the following conditions and the safety hazards that they present:
v Electrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
v Explosive hazards, such as a damaged CRT face or a bulging capacitor.
v Mechanical hazards, such as loose or missing hardware.
To inspect the product for potential unsafe conditions, complete the following
steps:
1. Make sure that the power is off and the power cord is disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and observe
any sharp edges.
3. Check the power cord:
v Make sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between
the external ground pin and the frame ground.
v Make sure that the power cord is the correct type, as specified in the
documentation for your BladeCenter unit type.
v Make sure that the insulation is not frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the server for any obvious unsafe conditions, such as metal
filings, contamination, water or other liquid, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
vi BladeCenter LS22 Type 7901 and LS42 Type 7902: Problem Determination and Service Guide
8. Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Guidelines for servicing electrical equipment
Observe the following guidelines when servicing electrical equipment:
v Check the area for electrical hazards such as moist floors, nongrounded power
extension cords, and missing safety grounds.
v Use only approved tools and test equipment. Some hand tools have handles that
are covered with a soft material that does not provide insulation from live
electrical current.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
v Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
v Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
v Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
v Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you are working with powered-on electrical equipment, use only one
hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.
– When you use a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
v Use extreme care when you measure high voltages.
v To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
v If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.

Information LED
Blade-error LED
Media-tray select
button
Power-control button
Power-on LED
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.
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,
4 BladeCenter LS22 Type 7901 and LS42 Type 7902: Problem Determination and Service Guide
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.
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 controls and LEDs” on page 3) 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
Chapter 1. Introduction 5
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 controls and LEDs” on page 3 for the
power-on LED states.
v If a power failure occurs, the BladeCenter unit and then the blade server can
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 controls and LEDs” on page 3). This starts an
orderly shutdown of the operating system, if this feature is supported by the
operating system.
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.
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,

Firmware updates
IBM periodically makes BIOS, service processor (BMC), diagnostic firmware, and
other firmware updates available for the blade server. Go to http://
www.ibm.com/bladecenter/ to download the latest firmware for the blade server;
then, install any updates using the instructions that are included with the
downloaded file.
Important: To avoid problems and to maintain system performance, always make
sure that the BIOS, service processor (BMC), and diagnostic firmware levels are
consistent for the blade servers within the BladeCenter unit.
Configuring the Gigabit Ethernet controller
One Ethernet controller is integrated on the blade server system board. A controller
provides a 1000 Mbps full-duplex interface for connecting to one of the
Ethernet-compatible I/O modules in I/O-module bays 1 and 2, which enables
simultaneous transmission and reception of data on the Ethernet local area
network (LAN). The Ethernet controller on the system board is routed to a
different I/O module in I/O-module bay 1 or bay 2. The routing from an Ethernet
controller to an I/O-module bay varies according to the blade server type and the
operating system that is installed.
You do not have to set any jumpers or configure the controller for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet controller. For device drivers and
information about configuring the Ethernet controller, see the Broadcom NetXtreme
Gigabit Ethernet Software CD that comes with the blade server. To find updated
information about configuring the controller, complete the following steps.
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/systems/support/.
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.
Note: If an 1801 error code is displayed during startup and the startup process
stops, the BIOS is trying to copy too much data from the device boot ROM into
write-protected RAM. To correct an 1801 error that halts the boot process, restart
the blade server, start the Setup Utility program (see “Using the Setup Utility
program” on page 11), and disable unnecessary ROM shadowing. Only the device
boot ROMs that enable the following components must be shadowed during
startup:
v Video
v Hard disk drive (if you are using this as a primary or secondary boot device)
v PXE (if you are using PXE as a primary or secondary boot device)
v One Ethernet controller (if you are using PXE as a primary or secondary boot
device)
Chapter 2. Configuring the blade server 17
The remaining options and components will be enabled by device drivers in the
operating system.
