Server powers-off with Light Path Diagnostics BRD and FAN LEDs lit - IBM System x3550 M3 (7944), x3650 M3 (7945)

Troubleshooting

Problem

The server is unable to complete Power On Self Test (POST) and powers off with Light Path Diagnostics (LPD) BRD and FAN Light Emitting Diodes (LEDs) lit. Logged events from the Integrated Management Module (IMM) shows the following. 1. I - 12/22/2011:14:18:45 - "Host Power" has been turned off 2. E - 12/22/2011:14:18:45 - Non-redundant:Insufficient Resources for "Cooling Zone 3" has asserted 3. E - 12/22/2011:14:18:40 - Non-redundant:Insufficient Resources for "Cooling Zone 1" has asserted 4. E - 12/22/2011:14:14:7 - Redundancy Lost for "Cooling Zone 2" has asserted 5. E - 12/22/2011:14:14:1 - Redundancy Lost for "Cooling Zone 3" has asserted 6. E - 12/22/2011:14:14:0 - Redundancy Lost for "Cooling Zone 1" has asserted

Workaround

The fix for this issue is to check the number of PCI Riser card assemblies installed in the server and make sure there is a PCI Riser card installed in connector 2.

Additional information

The root cause for this issue is a PCI Riser card assembly must be installed in connector 2, even if you do not have an option adapter to install.

To identify this issue, when the BRD LED is lit and all cooling zones are asserted at the same time, remove the server cover and check if PCI Riser card 2 LED is on.
