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 that you are working on. 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 options 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 blade 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.
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.
viii BladeCenter JS21 Types 7988 and 8844: Problem Determination and Service Guide
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 using 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 measuring 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.

server. It can take approximately 20 seconds to switch the keyboard and video
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 keyboard and video control
between blade servers:
NumLock NumLock blade_server_number Enter
4 BladeCenter JS21 Types 7988 and 8844: Problem Determination and Service Guide
Where blade_server_number is the two-digit number for the blade bay in which
the blade server is installed. When using some keyboards, such as the 28L3644
(37L0888) keyboard, you will need to hold down the Shift key while entering this
key sequence.
If there is no response when you press the keyboard/video select button, you can
use the management-module Web interface to determine whether local control has
been disabled on the blade server.
Activity LED: When this green LED is lit, it indicates that there is activity on the
hard disk drive or network.
Location LED: When this blue LED is lit, it has been turned on by the system
administrator to aid in visually locating the blade server. 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

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.
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.
Chapter 1. Introduction 5
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 buttons and LEDs” on
page 4) to start the blade server.
Notes:
1. Wait until the power-on LED on the blade server flashes slowly before
pressing the blade server power-control button. If the power-on LED is
flashing rapidly, the service processor in the management module is
initializing; therefore, 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 buttons and LEDs” on page 4 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),
the operating system supports the Wake on LAN feature, 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. However, the blade server can only
receive the Wake on LAN command through the ethernet ports that are
integrated into the system board, not through the ethernet ports on an installed
I/O expansion card.
6 BladeCenter JS21 Types 7988 and 8844: Problem Determination and Service Guide
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 buttons and LEDs” on page 4). This
also starts an orderly shutdown of the operating system, if this feature is
supported by the operating system.
Note: After turning 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.
v The management module can turn off the blade server.

8 BladeCenter JS21 Types 7988 and 8844: Problem Determination and Service Guide
Chapter 2. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the blade server.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, “Getting help and technical assistance,” on page 171 for more
information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST checkpoints
The power-on self-test (POST) in the firmware generates eight-digit checkpoint
codes. If the firmware detects a problem during POST, an eight-digit error code
will be displayed. See “POST checkpoint codes” for more information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 113 for more information.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 124 for more information.
POST checkpoint codes
When you turn on the blade server, it performs a series of tests to check the
operation of the blade server components. This series of tests is called the
power-on self-test, or POST. During POST, a series of eight-digit progress codes
(also known as checkpoints) is displayed on the console to indicate that the blade
server is initializing system resources.
Note: You must establish an SOL session with the blade server to view the codes
described in this section; the shared BladeCenter unit video cannot display these
codes.
If the POST is completed without detecting any problems, the firmware displays a
checkpoint indicating that an operating system is being loaded. Location code
information may also display on the operator panel during this time (see “Location
codes” on page 66).
If POST detects a problem, an eight-digit error code will be displayed and logged in
the BladeCenter management module event log. See “Attention codes” on page 34
and “Error codes” on page 37 for more information. A location code might be
displayed at the same time on the second line (see “Location codes” on page 66).
Note: Some POST codes may not display on the operator panel, these codes can
be viewed using the Progress Indicator History option in the SMS utility (see “Using
the SMS utility” on page 166).

Progress codes enable users and service personnel to know what the system is
doing as it initializes. These codes are not intended to be error indicators, but in
some cases a system could hang at one of the progress codes without displaying
an eight-digit error code. Any actions associated with the progress codes should be
taken only if the system hangs.
Progress codes
The following table lists the progress codes that may be displayed by the POST,
and the suggested actions to take if the system hangs on the progress code.
In the following progress codes, X can be any number or letter.
Notes:
1. For checkpoints with no associated location code, see “Light path diagnostics”
on page 124 to identify the failing component.
2. For checkpoints with location codes, see “Location codes” on page 66.
3. For problems persisting after completing the suggested actions, see “Checkout
procedure” on page 106 and “Solving undetermined problems” on page 135.
4. For eight-digit codes not listed here, see “Checkout procedure” on page 106.
v If the system hangs on a progress code, follow the suggested actions in the order in which they are listed
in the Action column until the problem is resolved.
v See Chapter 3, “Parts listing, Types 7988 and 8844,” on page 137 to determine which components are
CRUs and which components are FRUs.
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
