VRMOD

The system detected a voltage problem.

Complete the following to service this FRU:

1. Power off the system.
2. Unplug the AC.
3. Reseat the VRMs. Refer to Part locations and location codes for voltage regulator modules. Does that resolve the problem?
   • Yes: This ends the procedure.
   • No: Continue with the next step.
4. Replace the VRMs. Use the following table to determine the part number for the field replaceable unit (FRU).

   CCIN or FFC	Type and model	Part number	Description	Location code
   	8203-E4A, 8261-E4S	44V3845	Voltage regulators for processor 1	Un-P1-C13
   	8203-E4A, 8261-E4S	44V3841	Voltage regulator for processor 1	Un-P1-C18
   	8203-E4A, 8261-E4S	44V3845	Voltage regulators for processor 2	Un-P1-C19
   	8203-E4A, 8261-E4S	44V3841	Voltage regulator for processor 2	Un-P1-C20
   	8204-E8A	See System parts.	Voltage regulator assembly	Un-P1-C13-C10 through Un-P1-C16-C10
   	8204-E8A	See System parts.	Voltage regulator assembly	Un-P1-C13-C5
   	9406-MMA, 9117-MMA	42R7459	Voltage regulator assembly	Un-P2-C3
   	9406-MMA, 9117-MMA	42R7459	Voltage regulator assembly	Un-P2-C4
   	9406-MMA, 9117-MMA	42R7459	Voltage regulator assembly	Un-P2-C5

This ends the procedure.
