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.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: SPARC T7-4 Power Supply Replacement

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

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 return part to avoid any damages during shipping.

Note - The server contains four power supplies, which provide 2 + 2 power redundancy. If you need to only replace one or two power supply(s), you can do so while the server is operating, provided that at least two power supplies are online and working.

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.

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

WHAT ACTIONS ARE REQUIRED?:

Replace the Power Supply

1. Locate the bad Power Supply by checking for the following LEDs to be lit when a power supply fault is detected:

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

2. Looking at the front of the server, check the power supply fault LEDs to identify which power supply needs to be replaced.

Note -The amber Service Required LED is lit on the power supply that needs to be replaced.

Note - Each power supply is provided with a set of three LEDs (Fault, OK, AC Preset), which are located at the front of the server.

3. 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.

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

5. 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.

6. Pull the power supply out of the server.

7. Install the replacement power supply by opening the latch on the power supply, and align the power supply with the empty bay.

8. Slide the power supply into the chassis.

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

10. Insert the power cord into the AC connector for the power supply that you just installed.

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.
