REMOVAL/REPLACEMENT INSTRUCTIONS

PROBLEM OVERVIEW: faulty Power Supply

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

The server contains four power supplies, which provide 2+2 power redundancy. If you need to replace a power supply, you can do so while the server is operating as along as 2 power supplies remain operational all the time.

ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat

DAMAGE ALERT: Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc). If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the old part to avoid any damages during shipping.

WHAT ACTIONS ARE REQUIRED:

A) Locate a Faulty Power Supply

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

- System Service Required LEDs on the front panel and rear I/O module
- Fault LED on the faulty power supply

From the front of the server, check the power supply fault LEDs to identify which power supply needs to be replaced.
Each power supply is provided with a set of three LEDs, which are located at the front of the server.

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

B) Remove a Power Supply

The power supply is a hot-service component that can be replaced by a customer.

1. Locate the power supply in the server that you want to remove (see above)

2. Go to the rear of the server and locate the AC power connector at the rear of the server that supplies power to the faulty power supply.

3. Disconnect the power cord from the AC power connector that is associated with the power supply that will be replaced.

4. Go to the front of the server and, on the power supply to be removed, squeeze the release latches together, then pull the extraction lever toward you to disengage the power supply from the server.

5. Pull the power supply out of the server.

6. Install the replacement power supply.

C) Install a Power Supply

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

2. Slide the power supply into the chassis.

3. Press the lever against the power supply to fully seat the power supply in the server.

C) Verify Power Supply Functionality

1. Verify that the power supply Power OK and AC Present LEDs are lit, and that the Fault LED is not lit.

2. Verify that the front and rear Service Required LEDs are not lit.

If Step 1 and Step 2 indicate that no faults have been detected, then the power supply has been replaced successfully. No further action is required.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Verify Power Supply Functionality
