DRWRVRM

The voltage regulator module in an expansion drawer might be failing.

To determine the location of the voltage regulator module, complete the following steps:

  1. Is a location code available in the serviceable event view for this failing item?
    • Yes: Continue with the next step.
    • No: Go to step 3.
  2. The location code in the serviceable event view is either a cable adapter in the system unit or a voltage regulator module in an expansion drawer. For information about locations, see Part locations and location codes. Is the location code in the serviceable event view the location of a cable adapter in the system unit?
    • Yes: Go to step 4 to find the location of the voltage regulator module.
    • No: Go to step 5 to replace the voltage regulator module at this location.
  3. To determine the location of the failing item, complete the following steps:
    1. Record the dynamic reconfiguration connector (DRC) index, which is word 7 of the B700xxxx reference code.
    2. The DRC index is of the form xxxxyyyy, where yyyy is the hexadecimal bus number. Using the hexadecimal bus number, go to Card positions to find the location of the cable adapter that is attached to the expansion drawer that contains the failing item. Then, continue with the next step.
  4. Trace the expansion drawer cable from the cable adapter that was identified in the previous step to find the I/O module in the expansion drawer. The location of the I/O module is either Un-P1 or Un-P2. If the location of the I/O module is Un-P1, the location of the voltage regulator module is Un-P1-E1. If the location of the I/O module is Un-P2, the location of the voltage regulator module is Un-P2-E1. Continue with the next step.
  5. Is the system managed by a management console?
    • Yes: Use the management console to replace the failing item at the location that was identified in this procedure.
    • No: Continue with the next step.
  6. Use the following table to determine the service action to perform.
    Type and model Part number Description Location code Service action
    EMX0 PCIe3 expansion drawer See System parts. Voltage regulator module Un-P1-E1 or Un-P2-E1 Replace the voltage regulator module at the location that was identified in this procedure. For more information about EMX0 PCIe3 expansion drawer location codes and removal and replacement procedures, see EMX0 PCIe Gen3 I/O expansion drawer locations.

This ends the procedure.
