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 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:
vElectrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
vExplosive hazards, such as adamaged CRT face or abulging capacitor.
vMechanical 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:
vMake 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.
vMake sure that the power cord is the correct type, as specified in “Power
cords” on page 102.
vMake 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.
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:
vCheck the area for electrical hazards such as moist floors, nongrounded power
extension cords, power surges, and missing safety grounds.
vUse only approved tools and test equipment. Some hand tools have handles that
are covered with asoft material that does not provide insulation from live
electrical currents.
vRegularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
viii IBM System x3655 Type 7985 and 7943: Problem Determination and Service Guide

vDo not touch the reflective surface of adental mirror to alive electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches alive electrical circuit.
vSome rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
vDo not work alone under hazardous conditions or near equipment that has
hazardous voltages.
vLocate 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.
vDisconnect all power before you perform amechanical inspection, work near
power supplies, or remove or install main units.
vBefore 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.
vNever assume that power has been disconnected from acircuit. Check it to
make sure that it has been disconnected.
vIf 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 acomplete circuit that could cause an electrical shock.
–When using atester, set the controls correctly and use the approved probe
leads and accessories for that tester.
–Stand on asuitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
v
Use extreme care when measuring high voltages.
vTo 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.
vIf an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.

xvi IBM System x3655 Type 7985 and 7943: Problem Determination and Service Guide

Chapter 1. Start here for hardware problems
This chapter contains acheckout procedure that you should follow to solve
hardware problems in the server.
About the checkout procedure
Before you perform the checkout procedure for diagnosing hardware problems,
review the following information:
vRead the safety information that begins on page vii.
vThe diagnostic programs provide the primary methods of testing the major
components of the server, such as the system board, Ethernet controller,
keyboard, mouse (pointing device), serial ports, and hard disk drives. You can
also use them to test some external devices. If you are not sure whether a
problem is caused by the hardware or by the software, you can use the
diagnostic programs to confirm that the hardware is working correctly.
vWhen you run the diagnostic programs, asingle problem might cause more than
one error message. When this happens, correct the cause of the first error
message. The other error messages usually will not occur the next time you run
the diagnostic programs.
Exception: If there are multiple error codes or light path diagnostic LEDs that
indicate amicroprocessor error, the error might be in the microprocessor or in the
microprocessor socket. See “Microprocessor problems” on page 42 for
information about diagnosing microprocessor problems.
vBefore you run the diagnostic programs, you must determine whether the failing
server is part of ashared hard disk drive cluster (two or more servers that share
external storage devices). If it is part of acluster, you can run all diagnostic
programs except the ones that test the storage unit (that is, ahard disk drive in
the storage unit) or the storage adapter that is attached to the storage unit. The
failing server might be part of acluster if any of the following conditions are true:
–You have identified the failing server as part of acluster (two or more servers
that share external storage devices).
–One or more external storage units are attached to the failing server and at
least one of the attached storage units is also attached to another server or
unidentifiable device.
–One or more servers are located near the failing server.
Important: If the server is part of ashared hard disk drive cluster, run one test
at atime. Do not run any suite of tests, such as “quick” or “normal” tests,
because this might enable the hard disk drive diagnostic tests.
vIf the server is halted and aPOST error code is displayed, see “Error logs” on
page 28. If the server is halted and no error message is displayed, see
“Troubleshooting tables” on page 37 and “Solving undetermined problems” on
page 89.
vFor information about power-supply problems, see “Solving power problems” on
page 87 and “Power-supply LEDs” on page 53.
vFor intermittent problems, check the error log; see “Error logs” on page 28 and
“Diagnostic programs, messages, and error codes” on page 55.
©Copyright IBM Corp. 2006 1

Performing the checkout procedure
To perform the checkout procedure, complete the following steps:
1. Is the server part of acluster?
vNo: Go to step 2.
vYes: Shut down all failing servers that are related to the cluster. Go to step 2.
2. Complete the following steps:
a. Check the power supply LEDs, see “Power-supply LEDs” on page 53
b. Turn off the server and all external devices.
c. Check all internal and external devices for compatibility at
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
d. Check all cables and power cords.
e. Set all monitor controls to the middle positions.
f. Turn on all external devices.
g. Turn on the server. If the server does not start, see “Troubleshooting tables”
on page 37.
h. Check the system-error LED on the operator information panel. If it is
flashing, check the light path diagnostic LEDs on the system board (see
“System-board LEDs” on page 17).
i. Check for the following results:
vSuccessful completion of POST, which is indicated by asingle beep (see
“POST” on page 19 for more information)
vSuccessful completion of startup, which is indicated by areadable display
of the operating-system desktop
3. Did asingle beep sound and are there readable instructions on the main menu?
Note: Asingle beep indicates successful completion of POST and is not an
error.
vNo: Find the failure symptom in “Troubleshooting tables”, if necessary, see
“Solving undetermined problems” on page 89.
vYes: Run the diagnostic programs (see “Running the diagnostic programs” on
page 55).
–If you receive an error, see “Diagnostic error codes” on page 56).
–If the diagnostic programs were completed successfully and you still
suspect aproblem, see “Solving undetermined problems” on page 89.
Important:Clear the BMC system event log and system event/error log after
you correct all conditions. This will turn off the system event/error LED if all
conditions are corrected.
