FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4440 Power Supply needs replacement

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

Some versions of the Sun Fire X4440 Servers are equipped with redundant hot-swappable power supplies. Redundant power supplies enable you to remove and replace a power supply without shutting the server down, if the other power supply is online and working.

If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper air flow in the server.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Detecting Power Supply Failure

The following LEDs are lit when a power supply fault is detected:

* Front and rear Service Required LEDs
* Rear PS Failure LED on the bezel of the server
* Failure LED on the faulty power supply

Removing a Power Supply

1. Identify which power supply (0 or 1) requires replacement.

A lit (amber) failure LED on a power supply indicates that a failure was detected.

2. Gain access to the rear of the server where the faulty power supply is located.

3. Release the cable management arm (CMA)

The CMA is located at the rear of the server rack.

a. Press and hold the tab.

b. Rotate the cable management arm out of the way so that you can access the power supply.

4. Disconnect the power cord from the faulty power supply.

5. Grasp the power supply handle and press the release latch

6. Pull the power supply out of the chassis.

Installing a power supply

1. Align the replacement power supply with the empty power supply chassis bay.

2. Slide the power supply into the bay until it is fully seated

3. Reconnect the power cord (or cords) to the power supply (or supplies).

Verify that the AC Present LED is lit.

4. Close the CMA, inserting the end of the CMA into the rear left rail bracket

5. Verify that the following LEDs are not lit:

* Failure LED on the replaced power supply
* Service Required LED
* Front Service Required LED
* Rear Service Required LED

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

Verify the status of the power supplies.

Solaris OS: At the -> prompt, type the showenvironment command.
