REMOVAL/REPLACEMENT INSTRUCTIONS:

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

    

These servers are equipped with redundant hot-swappable power supplies. With redundant power supplies, you can remove and replace a power supply without shutting the server down, provided that the other power supply is online and working. The server offers two redundancy modes for the power supplies. Light load efficiency mode (LLEM) places PS1 in a warm standby condition while PS0 carries the entire load more efficiently by itself. If PS0 loses AC power or is extracted for replacement, PS1 takes over the load automatically. Some rare internal failures of PS0 could cause the server to lose power faster than PS1 can take over.
Disabling the LLEM Policy causes the power supplies to share the load at all times, at the expense of efficiency during light loads. For information about configuration policies, refer to the SPARC T3 Series Servers Administration Guide and the Oracle ILOM documentation.

Caution – If a power supply fails and you do not have a replacement available, to ensure proper airflow, leave the failed power supply installed in the server until you replace it with a new power supply


WHAT ACTIONS ARE REQUIRED:

Prepare for servicing:
Locate a Faulty Power Supply:

- Rear PS Fault LED on the front bezel of the server

- Service Action Required LED on the faulted power supply.

Note - The front and rear panel Service Action Required LEDs are also lit when the system detects a power supply fault.

a. Attach an antistatic wrist strap.
b. If necessary, release the cable management arm to access the power supplies.

Remove and Install a Power Supply

For Removing-

1. Disconnect the power cord from the power supply that displays an amber lit Service Action Required LED.
2. Press down on the release latch to open the ejector arm.
3. Slide the power supply out of the chassis.

Caution

- There is no catch mechanism on the power supply to prevent it from sliding completely out of the chassis. Use care when removing the power supply to avoid having it fall out of the chassis.

- Whenever you remove a power supply, you should replace it with another power supply; otherwise, the server might overheat due to improper airflow. If a new power supply is not available, leave the failed power supply installed until it can be replaced.


For Installing-

1. Align the power supply with the empty power supply chassis bay.
2. Slide the power supply into the bay until it is fully seated.
3. Move the release latch up to secure the power supply in place.
4. Reconnect the power cord to the power supply.
5. Verify that the AC OK LED is lit.
6. Verify that the following LEDs are not lit:
- Service Action Required LED on the power supply
- Front and rear Service Action Required LEDs
- Rear PS Failure LED on the bezel of the server

Caution
- Install an A239A power supply, labeled for upright installation, in the server. The A239A power supply correctly exhausts air from the rear of the server. Do not install an A239 power supply, which might cause the system to overheat and shut down.

OBTAIN CUSTOMER ACCEPTANCE

1. Verify that the Service Required LED on the replaced power supply is not lit.
2. Verify that the Top Fan LED and the Service Required LED on the front of the server are not lit.
3. Run the ILOM show faulty command to verify that the fault has been cleared.

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Verify functionality, no service LEDs or messages.
