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 110.
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 System x3850 Type 8863, 7362: 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.

jumper to pins 2 and 3 to force the server to startup when you
connect the server to ac power.
Power-on password (J9) The default position is pins 1 and 2. Change the position of this
jumper to pins 2 and 3 to bypass the power-on password check.
Changing the position of this jumper does not affect the
administrator password check if an administrator password is set. If
the administrator password is lost, the operator information panel
must be replaced.
Boot recovery (J14) The default position is pins 1 and 2 (use the primary page during
startup). Move the jumper to pins 2 and 3 to use the secondary
page during startup.
Wake on LAN® bypass (J15) The default position is pins 1 and 2. Move the jumper to pins 2 and
3 to prevent a Wake on LAN packet from waking the system when
the system is in the powered-off state.

Chapter 2. Diagnostics
This chapter provides basic troubleshooting information to help you solve some
common problems that might occur with 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 157 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 Problem isolation tables
Use these tables to help you diagnose various symptoms. See “Problem isolation
tables” on page 47.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 60 for more information.
v Diagnostic programs and error messages
The diagnostic programs are stored in memory on the microprocessor tray.
These programs are the primary method of testing the major components of the
server. See “Diagnostic programs, messages, and error codes” on page 69 for
more information.
POST
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options in the server. This series of tests is
called the power-on self-test, or POST.
If POST finishes without detecting any problems, a single beep sounds, and the first
screen of the operating system opens, or an application program starts.
If POST detects a problem, more than one beep might sound, or an error message
appears on the screen. See “Beep code descriptions” on page 14 and “POST error
codes” on page 20 for more information.
Notes:
1. If a power-on password is set, you must type the password and press Enter,
when prompted, before POST will continue.
2. A single problem might cause several error messages. When this occurs,
correct the cause of the first error message. The other error messages usually
will not occur the next time you run the test.

POST beep codes
A beep code is a combination of short or long beeps or a series of short beeps
separated by pauses. For example, a “1-2-3” beep code is one beep, a pause, two
beeps, a pause, and three beeps.
When POST is completed, one beep is emitted to indicate that the server is working
correctly. If POST detects a problem during startup, other beep codes might occur.
See “Beep code descriptions” to help diagnose and solve problems that are
detected during startup. If no beep code sounds, see “No-beep symptoms” on page
18.
Beep code descriptions
The following table describes the beep codes and suggested actions to correct the
detected 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 8863, 7362,” on page 107 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.
