ACMODUL

Your server has suffered a power loss. This procedure will help you determine the source of the power loss condition that brought you here.

If the system or expansion unit that exhibited the power loss powers on normally, or stays powered on after an ac power failure, replacement of parts might not be needed. Power failures can be caused by brown outs, building or room power receptacle power loss, loose or disconnected power cords, or possible hardware conditions.

  1. Is the failing unit configured with a redundant power supply option (or dual line cord feature)?
    • No: Continue with the next step.
    • Yes: A service representative must perform power isolation procedure PWR1911 which is located in the service guide for the system unit.
  2. Are all the units powered on?
    • Yes: This error might have been caused by an ac power outage. If the system will power on without an error, no parts need to be replaced. This ends the procedure.
    • No: On the unit that does not power on, verify that the power outlet is supplying the correct power for the unit. Also, ensure that both ends of the power cord (from the unit that does not power on) are connected correctly and securely. If you find a problem, correct the problem, this ends this procedure.

      If you cannot find the problem, the following steps must be performed by a trained service representative:

      1. Use a multimeter to measure the voltage at the system end of the power cord.
      2. Is the voltage correct, refer to the following table?
        Model or expansion unit Correct voltage
        5796, 7314-G30, or 8204-E8A 200V to 240V AC or 200V to 220V DC
        9406-MMA, 9117-MMA, 7311-D11, or 7311-D20 200V to 240V AC
        • Yes: Continue with the next step.
        • No: Go to the step 4.
  3. Replace the failing power supply, 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
      9406-MMA, 9117-MMA 42R8010 Power supply 1 Un-E1
      9406-MMA, 9117-MMA 42R8010 Power supply 2 Un-E2
      8204-E8A 44V3559 Power supply 1 (ac supply) Un-E1
      8204-E8A 44V3559 Power supply 2 (ac supply) Un-E2
      8204-E8A 42R6607 Power supply 1 (dc supply) Un-E1
      8204-E8A 42R6607 Power supply 2 (dc supply) Un-E2
      5790, 7311-D11 22R3958 Power supply 1 Un-E1
      5790, 7311-D11 22R3958 Power supply 2 Un-E2
      0595, 5095, 7311-D20 39J2781 Power supply 1 Un-E1
      0595, 5095, 7311-D20 39J2781 Power supply 2 Un-E2
      5796, 7314-G30 42R4491 Power supply 1 Un-E1
      5796, 7314-G30 42R4491 Power supply 2 Un-E2
      5094 39J5273 Power supply 0 Un-P00
      5094 39J5273 Power supply 1 Un-P01
      5094 39J5273 Power supply 2 Un-P02
      5094 39J5273 Power supply 3 Un-P03
      5094 39J5171 AC module A01 Un-A01
      5094 39J5171 AC module A02 Un-A02
  4. Perform the following:
    1. Disconnect the power cord from the customer's power outlet.
    2. Use a multimeter to measure the voltage at the customer's power outlet.

      Is the voltage correct?

      • Yes: Exchange the failing power cord. This ends the procedure.
      • No: Perform the following:
        1. Inform the customer that the voltage at the power outlet is not correct.
        2. After the voltage at the power outlet is correct, reconnect the power cord to the power outlet. This ends the procedure.
