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.

TIME ESTIMATE: 120 minutes

FIELD ENGINEER INSTRUCTIONS

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

Physical Domains must be shut down. Server must be powered off.

This component is COLD service only.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Halt and power down the server.

2. Use a T20 Torx screwdriver to remove four mounting screws from the front filler panel.

3. Pull the front filler panel out of the slot.

4. Remove the upper fan cage. (see M5-32 How to Replace a Faulty Upper Fan Cage Assembly )

5. Remove the scalability cage (see M5-32 How to Replace a Faulty Scalability Cage )

6. Remove the lower fan cage. (see M5-32 How to Replace a Faulty Lower Fan Cage Assembly )

7. Remove the scalability assembly (see M5-32 How to Replace a Faulty Scalability Assembly )

8. Locate the faulty cable.

The same cable can used in two separate places. Identify which cable that you intend to replace.
Each of these cables has four connectors, labeled P1, P2, P3, and P4.

9. Undo the T20 shoulder screws on connectors P3 and P4.

Caution – Take care not to drop the screws. These are not captive screws .

10. Undo the T20 shoulder screws on connectors P3 and P4.

11. Replace the fan power cable

12. Connect the T20 shoulder screws to attach connectors P3 and P4 to brackets on the side of server cabinet

13. Use T20 spring screws to attach connectors P1 and P2 to the midplane.

14. Install the scalability assembly (see M5-32 How to Replace a Faulty Scalability Assembly )

15. Install the lower fan cage. (see M5-32 How to Replace a Faulty Lower Fan Cage Assembly )

16. Install the scalability cage (see M5-32 How to Replace a Faulty Scalability Cage )

17. Install the upper fan cage. (see M5-32 How to Replace a Faulty Upper Fan Cage Assembly )

18. Re-install the front filler panel. Use a T20 Torx screwdriver to install four mounting screws in the panel.

19. Turn on AC power to the server.

20. Restart the server.

21. Return the faulted component to Oracle.
