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.
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 “Power
cords” on page 65.
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, nongrounded power
extension cords, power surges, 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 currents.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
viii IBM xSeries 306m Types 8849 and 8491: 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.

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 111 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 24.
v System board LEDs
Use the system board LEDs to diagnose system errors quickly. See “System
board LEDs” on page 36 for more information.
v Diagnostic programs, messages, and error messages
The diagnostic programs are the primary method of testing the major
components of the server. The diagnostic programs are on the IBM Enhanced
Diagnostics CD. See “Diagnostic programs, messages, and error codes” on page
38 for more information.
POST
When you turn on the server, it performs a series of tests to check the operation of
the server components and some optional devices in the 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 detects a problem, one or more beeps might sound, or an error message
is displayed. See “POST beep codes” and “POST error codes” on page 15 for more
information.
POST beep codes
A beep code is a combination of short or long beeps or 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, and pause, and three short beeps. A beep code indicates
that POST has detected a problem.
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 diagnostics LEDs that indicate a
microprocessor error, the error might be in the microprocessor or in the
microprocessor socket. See “Microprocessor problems” on page 29 for information
about diagnosing microprocessor problems.

Chapter 2. Diagnostics 13
Error logs
The POST error log contains the three most recent error codes and messages that
were generated during POST. The system event log contains messages that were
generated by the mini-BMC. The system event/error log is a combined log that
contains messages that were generated during POST and all system status
messages from the mini-BMC.
The system event/error log and BMC system event log are limited in size. When
each log is full, new entries will not overwrite existing entries; therefore, you must
periodically clear these logs through the Configuration/Setup Utility program (the
menu choices are described in the User’s Guide). When you are troubleshooting an
error, be sure to clear both the logs so that you can find current errors more easily.
Important: After you complete a repair or correct an error, clear the BMC system
event log to turn off the system-error LED on the front of the server.
Entries that are written to the system event/error log during the early phase of
POST show an incorrect date and time as the default time stamp; however, the
date and time are corrected as POST continues.
Each system event/error log entry appears on its own page. To move from one
entry to the next, use the up-arrow and down-arrow keys.
You can view the contents of the POST error log, the system event log, and the
system event/error log from the Configuration/Setup Utility program.
When you are troubleshooting PCI-X slots, note that the error logs report the PCI-X
buses numerically. The numerical assignments vary depending on the configuration.
You can check the assignments by running the Configuration/Setup Utility program
(see the User’s Guide for more information).
Viewing error logs from the Configuration/Setup Utility program
For complete information about using the Configuration/Setup Utility program, see
the User’s Guide.
To view the error logs, complete the following steps:
1. Turn on the server.
2. When the prompt Press F1 for Configuration/Setup appears, press F1. If you
have set both a power-on password and an administrator password, you must
type the administrator password to view the error logs.
3. Use one of the following procedures:
v To view the POST error log, select Error Logs, and then select POST Error
Log.
v To view the BMC system event log, select Advanced Setup --> Baseboard
Management Controller (BMC) Setting --> System Event Log
v To view the combined system event/error log, select Error logs, and then
select System Event/Error Log.
Clearing the error logs
For complete information about using the Configuration/Setup Utility program, see
the User’s Guide.
To clear the error logs, complete the following steps:
1. Turn on the server.
