Maintenance and Troubleshooting      4-5

TROUBLESHOOTING

This subsection provides information that helps isolate and repair system malfunctions at the
field level. Step-by-step instructions for diagnosing and solving system hardware problems
are provided.

If disassembly is required, see Section 5. Connector pin assignments are given in
Appendix A. Jumper settings are given in the appendices.

Diagnosing and Solving Problems

One beep indicates that the system has completed its POST test. If intermittent beeping
occurs, power off the system and try again. If the beeping persists, see Table 4-2. The table
summarizes problems that may develop during system operation and lists (in sequential
order) suggested corrective actions.

 Table 4-2   Problems and Solutions

 Problem

 Symptom

 Solution

 No power

 Power lamp on computer
status panel will not light.

 1. Check that the power cord is plugged
into the AC connector on the computer.

Check that the other end of the cord is
plugged into a live properly grounded
AC power outlet.

 

 

 2. Check cable connections between the
power supply and system board.

 

 

 3. Systematically eliminate possible
shorted PCBs by removing cables and
expansion boards.

 

 

 4. Check the +5 and +12 power supply
voltages (see Appendix A, “Connector
Pin Assignments”). Measure voltages
with the system board installed.

 

 

 5. Replace the power supply.

 

 

 6. Replace the system board.

 Power supply
malfunction

 Any of the following conditions
could occur:

 1. Perform steps 1 through 4 listed in
this table under No Power.

 

 Front panel lamps out, diskette
and/or hard disk drives do not
spin, monitor blank, interface
ports not working, and
keyboard lamp out and/or
cannot input from keyboard.

 2. Check power supply voltages.
Voltages should be measured with a
load on them (system board plugged in).
See Appendix A for connector pin
assignments and Section 1 for power
supply specifications.

 

 

 3. Replace the power supply.
