Check the power supply voltages (see “Power Supply” on page 2-32). If the
voltages are correct, return here and continue with the following steps:
1. Power-off the system unit.
2. Perform the following checks, one by one, until you have isolated the
problem FRU (refer to “Parts/Test Point Locations” on page 5-1 for
locations):
Ÿ
Check all system board jumper positions.
Ÿ
Check all adapter card jumper positions.
Ÿ
Check all adapter card switch settings.
Ÿ
Check all device jumper positions.
Ÿ
Check all cables and connectors for proper installation.
If the jumpers, switch settings, and voltages are correct, return here and
continue:
3. Remove or disconnect the following, one at a time:
a. Non-IBM devices
b. External devices
c. Sound adapter card
d. Any adapters
e. Modem card
f. Riser card
g. Zip Drive, if installed
h. CD-ROM drive
i. Diskette drive
j. Hard disk drive
k. DIMMs
4. Power-on the system unit.
5. Repeat steps 1 through 4 until you find the failing device or adapter.
If the symptom changes, go to “Index of Symptoms, Messages, Error Codes,
or Beeps” on page 2-9 or to the check procedure for the last item tested.
Replace the last item tested if the system operates normally after removing
the last item.
Note: If you are unable to find a check procedure that corresponds to the
device or error code, you either have an IBM device with its own
service manual or a device not supported by IBM diagnostic tests.
If all devices and adapters have been removed, and the problem remains:
1. Remove all cables from connectors on the system board except the
power supply and switch cables. See “System Board Layout” on
page 5-2 for connector locations.
