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” on page 30.

Front Panel LEDs:

Rear Power Supply Status LED (amber) Indicates the state of the power supplies:

Off – Indicates a steady state, no service action is required.
On – Indicates a fault with one of the power supplies.

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

See “Power Supply LEDs” on page 122.

The status of each power supply is represented by three LEDs. The LEDs are located to the left of the fan of each power supply.

See “Rear Panel LEDs” on page 33.

This table describes the functionality of the power supply LEDs.

Location	Name	Color	State and Meaning
*Top*	OK	Green	On – Power supply is functional without fault.
			Off – Power supply is off, in standby mode or initializing.
Middle	Attention (Service Required)	Amber	On – Normal fault detected.
			Off – No faults detected.
Bottom	AC or DC	Green	On – Input power present and good.
			Off – Input power not present.

If a power supply is faulty, replace it. See “Remove a Power Supply” on page 124.

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” on page 124.

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).

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.

If a FRU value different from /SYS/PSx is displayed, see “Component Service Task Reference” on page 65 to identify which component is faulty.

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

See “Display Faults (faultmgmt Shell)” on page 48.

Check the Fault class and Description fields for more information.

If a power supply is faulty, replace it.

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.

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

See “Detecting and Managing Faults”.

Remove a Power Supply

Removing a power supply is a hot-swap operation. You do not need to power off the server before you remove the power supply.

1. Determine which power supply to remove. See “Locate a Faulty Power Supply” above.

2. If you have not prepared for service, do so now. See “Preparing for Service”.

3. Disconnect the power cord from the power supply.

See “Disconnect Power Cords and Data Cables” on page 70.

4. Press the release tab to the left and pull on the handle.

5. Continue to pull on the handle to slide the power supply out of the chassis.

6. Set the power supply aside.

Install a Power Supply

Installing a power supply is a hot-swap operation. You do not need to power off the server before installing the power supply.

1. Align the power supply to the location where it installs into the chassis.

The PDB connector is toward the chassis, and the release tab is on the left.

2. Slide the power supply into the chassis until the power supply seats and the release tab clicks.

3. Attach the power cord.

See “Connect Power Cords” on page 260.

Verify a Power Supply

After you install a power supply, you can verify its functionality.

1. Access Oracle ILOM.

See “Access the SP (Oracle ILOM)” on page 28.

2. Reset the power supply.

        -> set /SYS/PSx clear_fault_action=true
        Are you sure you want to clear /SYS/PS0 (y/n)? y
        Set 'clear_fault_action' to 'true'
        ->

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

3. Verify that the power supply is no longer considered faulty, then return to this procedure.

See “Locate a Faulty Power Supply” on page 122.

4. 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).

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Confirm there are no faults reported in the appliance BUI and Cluster. "Mark Repaired" any prior faults related to the PSU if required.

OBTAIN CUSTOMER ACCEPTANCE

PARTS NOTE:

Consult System handbook for appropriate model.
