Undetermined problems
You are here because the diagnostic tests did not identify the failure, the Devices List
is incorrect, or the system is inoperative. If this has occurred proceed as follows:
Note: A corrupt CMOS can cause undetermined problems.
1. Ensure that the system is connected to an AC power source.
2. Press the power switch.
Note: If AC power has been removed from system, allow 30 seconds after
restoring AC power before pressing power control button. See “Turning
on the server” on page 8.
Note: If system was powered-on when AC power was removed, system should
restart automatically when AC power is restored.
3. Are the power indicator LEDs (front and rear) ON or blinking?
a. No. Check AC power into system. If AC power into system is good, suspect
the following FRUs in the order listed:
1) Power supply
2) System board
b. Yes, power indicators (front and rear) are blinking.
Turn switch 5 on switch block 1 to ON. If system powers-on, turn switch 5 on
switch block 1 to OFF and replace front panel assembly. If system does not
power-on, reconfigure system to minimum operating requirements and retry.
If problem remains, suspect the following FRUs in the order listed:
1) Power supply
2) System board
c. Yes, power indicator LEDs (front and rear) are ON.
1) Power-off system.
2) Ensure system is cabled correctly.
3) Reconfigure system to minimum operating requirements.
Note: Minimum operating requirements are:
a) 1 Power Supply
b) System Board
c)
1 Microprocessor
d) 1 Terminator Card
e) Memory Module (with a minimum of 128 MB DIMM)
