There are two types of CRUs in the server:
•
Externally accessible CRUs (eCRUs)
•
Internally accessible CRUs (iCRUs)
In the following two lists, asterisks identify those CRUs identifiable by Diagnostic Panel LEDs
when they are faulty or have failed.
The following is a list of all external CRUs (eCRUs) in the server:
•
Bulk power supply (1 and 2)
1
•
Console device
•
Power cords
•
Modems/UPS
•
DVD and 2.5 HDDs (SAS or SATA)
1
•
Cooling fans (4-6)
The following is a list of all the internal CRUs (iCRUs) in the server:
•
I/O board assembly
•
Core I/O board
1
•
Core LAN HBA
•
SAS Disk HBA
•
CPU board and CPUs
1
•
Disk BP board (1 and 2)
•
Memory extender and DIMMs
1
•
FP and Diagnostic LED board
•
HBAs (optional)
•
I/O VRM
•
Cooling Fans (1-3)

•
Midplane board
•
Interconnect board
System Build-Up Troubleshooting Procedure
Use this procedure only when the system powers on and remains powered on but does not enter
into or pass POST or does not boot to EFI menu.
1.
Remove the AC power cord from each bulk power supply and extend the server chassis, if
racked.
2.
Remove all of the HDDs from the front of the chassis, then the memory extender and CPU
board CRUs.
3.
Remove the top cover to gain access to, and remove, everything but the I/O backplane board
and core I/O board CRUs.
4.
Plug in the AC power cord(s) and the iLO 2 MP and system console should come alive and
you should have the following CRU IDs listed after executing the
CM
>
DF
command:
CRU IDs:
--------
02-Power Converter 03-Power Supply 0 04-Power Supply1
1. Has an associated diagnostic LEDs, which indicates device fault or failure.
