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.

Pull the rear LED panel out of its slot and disconnect the interface cable.

6. Unpack the replacement Rear LED Panel from its ESD safe packaging.

7. Pack the faulty Rear LED Panel into its ESD safe packaging.

8. Install the replacement Rear LED Panel:

Connect the interface cable to the rear LED panel.
Push the interface cable into the opening at the rear of the slot while you put the rear LED panel in the slot.
Use a Torx T10 screwdriver to install the screws at the sides of the rear LED panel.

9. Verify all six external breakers are still in the Off position.

10. Warn bystanders that you are preparing to restart the server.

11. Turn on all AC power and start the server:

Connect all six AC cords to their respective AC outlets.
Turn on all external breakers for the server.
Turn the key switch on the Front Panel of the server to the On position.
