TPMD_OV

The thermal power management firmware has detected that the system is operating without power supply redundancy.

Before you begin

The maximum power limit for the operational power supply has been reached and action has been taken to reduce power consumption. A power-related SRC might or might not have been logged.

If you need additional information for failing part numbers, location codes, or removal and replacement procedures, see:
Note: Storage complex repair actions must always be managed from the management console. To replace any FRUs identified in this procedure, use Storage Facility Management > storage facility > Exchange Parts. If the FRUs are listed in this or another Serviceable Event, select them from there.

Procedure

  1. Check the error log for power-related SRCs (1xxx yyyy, BE19xxxx). Did you find a power-related SRC?
    • No, continue with the next step.
    • Yes, resolve the problem by using the power-related SRC. This ends the procedure.
      1. One or more HMC repair screens might prompt you for the result of exiting this MAP. Select Delay the repair if prompted for the result of using the service procedure.
  2. Are any of the power supplies missing?
    • No, continue with the next step.
    • Yes, install the missing power supply. This ends the procedure.
  3. Check the LEDs on the power supplies (see PWRSPLY for descriptions of the LEDs and their meaning). If the LEDs indicate that one of the power supplies is failing, replace it first. If the LEDs do not indicate a failure, replace the power supplies one at a time. Did replacing the power supplies resolve the problem?
    • No, contact your next level of support. This ends the procedure.
    • Yes, this ends the procedure.
