VRMOD

The system detected a voltage problem.

Perform the following to service this FRU.

  1. Power off the system.
  2. Unplug the AC.
  3. Reseat the VRMs. Refer to the "Locations" section of the service guide for the system unit 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, 9407-M15, 9408-M25 44V3845 PVoltage regulators for processor 1 Un-P1-C13
      8203-E4A, 9407-M15, 9408-M25 44V3841 Voltage regulator for processor 1 Un-P1-C18
      8203-E4A, 9407-M15, 9408-M25 44V3845 Voltage regulators for processor 2 Un-P1-C19
      8203-E4A, 9407-M15, 9408-M25 44V3841 Voltage regulator for processor 2 Un-P1-C20
      8204-E8A, 9409-M50   Voltage regulator assembly Un-P1-C13-C10 through Un-P1-C16-C10
      8204-E8A, 9409-M50   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.
