Locate a Faulty Power Supply

You must determine which power supply is faulty before you replace it.

1. Check to see if any System Service Required LEDs are lit or flashing.

   See Interpreting Diagnostic LEDs.

2. Visually inspect the power supplies to see if any of their status LEDs are lit or flashing.

   See Power Supply LEDs.

   If a power supply is faulty, replace it. See Remove a Power Supply.

3. In Oracle ILOM, check the health of the power system.

   -> show /System/Power 
    /System/Power
    	Targets:
    	Properties:
    		health = OK
    		health_details = -
   ...
   ->

   If the health_details property identifies a faulty power supply, replace it. See Remove a Power Supply.

4. Check the health of the individual power supplies.

   -> show /System/Power/Power_Supplies/Power_Supply_x 
    /System/Power/Power_Supplies/Power_Supply_0
    	Targets:
    	Properties:
    		health = OK
    		health_details = -
   ...
   ->

   where x is the number of the power supply, either 0 (lower power supply) or 1 (upper power supply).

   If the health_details property identifies the power supply as faulty, replace it. See Remove a Power Supply.

5. Verify that a power supply is faulty.

   If a power supply is faulty, you will see /SYS/PSx under the Value heading, where x is 0 (lower power supply) or 1 (upper power supply).

   For example:

   -> show faulty
   Target              | Property               | Value
   --------------------+------------------------+-------------------------------
   /SP/faultmgmt/0     | fru                    | /SYS/PS0
   ...
   ->

   If a power supply is faulty, replace it. See Remove a Power Supply.

   If a FRU value different from /SYS/PSx is displayed, see Component Service Task Reference to identify which component is faulty.

6. Use the Oracle ILOM faultmgmt shell to identify the faulty component.

   See Display Faults (faultmgmt Shell).

   Check the Fault class and Description fields for more information.

   If a power supply is faulty, replace it. See Remove a Power Supply.

7. Within the Oracle ILOM interface, verify the voltage output.

   -> show /SYS/PSx/V_12V value
    /SYS/PS0/V_12V
    	Properties:
    		value = 12.027 Volts
   ->

   where x is 0 (lower power supply) or 1 (upper power supply).

   If the power supply is faulty, replace it. See Remove a Power Supply.

8. If you are unable to determine if a power supply is faulty, seek further information.

   See Detecting and Managing Faults.
