PWR2402

Use this procedure when the server detects an error in the power system.

For important safety information before continuing with this procedure, see Power isolation procedures.

Refer to System FRU locations for instructions for removing and replacing any FRUs called out by the following procedure.

  1. Is the SRC 1xxx-8700 or 8701?
    No:
    Return to the Start of call procedure. This ends the procedure.
    Yes:
    Continue with the next step.
  2. Measure voltages on the BPR(s). If the SRC is 1xxx8720, you should measure the voltage on BPR-A (front). If the SRC is 1xxx8721, you should measure the voltage on BPR-B (rear). The test points are on the left side of BPR-1 and BPR-2. Using the labeled test points on the face of the BPR, measure the voltages between the following:
    • phase A and phase B
    • phase B and phase C phase
    • C and phase A
    Are all of the meter readings greater than 180 V ac?
    No:
    Inform the customer that power voltage at the input to the BPR is either missing or too low and needs to be corrected. This ends the procedure.
    Yes:
    Go to step 4.
  3. Does the check confirm that the customer's voltage levels missing or too low?
    No:
    Replace the power cord (see Cables for the proper part number). This ends the procedure.
    Yes:
    The customer must correct the voltage levels. This ends the procedure.
  4. Exchange the following FRUs, one at a time, until the problem is resolved.
    Note: See System FRU locations for information on FRU locations for the system that you are servicing.
    • Bulk power regulator (BPR) 1
    • BPR 2
    • BPR 3
    • BPR 4
    • Bulk power controller (BPC)
    • Bulk power assembly (BPA)

    This ends the procedure.
