System board Undetermined problems You are here because the diagnostic tests did not identify the failure, the Devices List is incorrect, or the system is inoperative. Note: A corrupt CMOS can cause undetermined problems. Note: A corrupt BIOS can cause undetermined problems. (See "Recovering BIOS code" on page 16.) Check the LEDs on all the power supplies, see "Power supply LED errors" on page 92. If the LEDs indicate the power supplies are working correctly, return here and do the following: 1. Power-off the computer. 2. Be sure the system is cabled correctly. 102 Hardware Maintenance Manual: xSeries 342 Type 8669

Undetermined problems
You are here because the diagnostic tests did not identify the failure, the Devices
List is incorrect, or the system is inoperative.
Note:
A corrupt CMOS can cause undetermined problems.
Note:
A corrupt BIOS can cause undetermined problems. (See “Recovering BIOS
code” on page 16.)
Check the LEDs on all the power supplies, see “Power supply LED errors” on
page 92. If the LEDs indicate the power supplies are working correctly, return here
and do the following:
1.
Power-off the computer.
2.
Be sure the system is cabled correctly.
