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 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.
inspect the product for potential unsafe conditions, complete the following steps:
To
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.
Remove the cover.
4.
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.
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, non-grounded 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 HS20 Type 7981 and 1884: 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.
Use extreme care when measuring high voltages.
v
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.

KVM (keyboard/video/mouse) select button: Press this button to associate the
shared BladeCenter unit keyboard, video, and mouse ports with the blade server.
The LED on this button flashes while the request is being processed then is lit
when the ownership of the KVM has been transferred to the blade server. It can
take approximately 20 seconds to switch the KVM 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 blade_server_number Enter
Where blade_server_number is the two-digit number for the blade bay in which
the blade server is installed.
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.
Note:
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 keyboard, video, and mouse, a
delay of up to 1 minute occurs the first time that you switch the keyboard, video,
and mouse 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 takes place in the normal KVM
switching time frame (up to 20 seconds).

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 controls, LEDs, and connectors” 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. During this time, the
management-module is initializing; therefore, the power-control button on the
blade server does not respond.
2. While the blade server is powering-up, the power-on LED on the front of the
server is lit. See “Blade server controls, LEDs, and connectors” on page 4 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 means of the management-module.
v If the operating system supports the Wake on LAN
power-on LED is flashing slowly, the Wake on LAN feature can turn on the blade
server, if the Wake on LAN feature has not been disabled through the
management-module.

feature and 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, LEDs, and connectors” 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.

Chapter 2. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the 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 83 for more
information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST” for more
information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 25 for more information.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 38 for more information.
v Diagnostic programs, messages, and error codes
The diagnostic programs are the primary method of testing the major
components of the blade server. These programs are stored in read-only memory
(ROM) on the blade server. See “Diagnostic programs, messages, and error
codes” on page 41 for more information.
POST
When you turn on the blade server, it performs a series of tests to check the
operation of the blade server components and some optional devices in the blade
server. This series of tests is called the power-on self-test, or POST.
If a power-on password is set, you must type the password and press Enter, when
prompted, for POST to run.
If POST is completed without detecting any problems, a single beep sounds, and
the blade server startup is completed.
If POST detects a problem, more than one beep might sound, or an error message
is displayed. See “Beep code descriptions” on page 10 and “POST error codes” on
page 18 for more information.
POST beep codes
A beep code is a combination of short or long beeps or a series of short beeps that
are separated by pauses. For example, a “1-2-3” beep code is one short beep, a
pause, two short beeps, a pause, and three short beeps. A beep code other than
one beep indicates that POST has detected a problem. To determine the meaning
of a beep code, see “Beep code descriptions” on page 10. If no beep code sounds,
see “No-beep symptoms” on page 16.

Beep code descriptions
The following table describes the beep codes and suggested actions to correct the
detected problems.
A single problem might cause more than one error message. When this occurs,
correct the cause of the first error message. The other error messages usually will
not occur the next time POST runs.
Exception: If there are multiple error codes or light path diagnostics LEDs that
indicate a microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 30 for information
about diagnosing microprocessor problems.
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 3, “Parts listing, Type 7981 and 1884,” on page 53 to determine which components are
customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
