Solution

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.

PROBLEM OVERVIEW: SPARC S7-2L Internal NVMe Cables between the motherboard NVME controller and the 8 or 24 Disk Backplane 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 FRU just as the new FRU was packaged, to avoid any damages during shipping.

Note: A data backup is not a prerequisite but is a wise precaution.

Customer should perform an orderly and graceful shutdown of applications and OS to get the OpenBoot PROM prompt. Then power off the server and remove the AC power cords from the system.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove Internal NVMe Cables between the motherboard NVME controller and the Disk Backplane

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Extend the server to the maintenance position in the rack.
c. Attach an antistatic wrist strap to your wrist and then to a metal area on the chassis.

Caution - Components inside the chassis might be hot. Use caution when servicing components inside the chassis.

2. Remove the top cover and open the fan door.

a. Open the fan Door. Slide the fan door latches forward and swing the door up to the open position
b. To open the server top cover, press and hold down the top cover release button and use the recessed area to slide the top cover toward the rear of the server about 0.5 inches (12.7 mm).
c. Lift the cover off the chassis and set it aside.

3.Remove clear plastic air duct assembly cover.

4. Remove all of the server fan modules.

5. Remove the server mid-wall.

a. Loosen the four green captive screws that secure the mid-wall to the server chassis, using a No. 2 Phillips screwdriver.
b. Lift up the mid-wall slightly to disengage it, then lift it out of the server and set it aside.

5. Disconnect the NVMe cables from the drive backplane by pressing the latches on the cable connectors and pull the connectors.

6. Disconnect the cables from the motherboard.

7. Carefully pull the NVMe card cables from the side of the chassis and remove them from the server.

Install Internal NVMe Cables between the motherboard NVME controller and the Disk Backplane

1. Guide the NVMe card cables along the side of the chassis.

2. Connect the cables to the drive backplane.

a. Connect the cable labeled "A" to the connector on the drive backplane labeled "NMVe A".
b. Connect the cable labeled "B" to the connector on the drive backplane labeled "NMVe B".

3. Connect the NVMe card cables to the motherboard (2).

a. Connect the cable labeled "2,3" to the connector on the motherboard labeled "2,3". This is the connector closer to the front of the server.
b. Connect the cable labeled "0,1" to the connector on the motherboard labeled "0,1". This is the connector closer to the rear of the server.

4. Install the server fan modules.

5. Install the server mid-wall.

a. Position the mid-wall over the front of the motherboard so that it engages the mushroom-shaped standoffs that are located on the server chassis sidewall.
b. Ensure that SAS cables are not pinched by the mid-wall and that they run beside the mid-wall and not under it.
c. Tighten the four green captive screws to secure the mid-wall to the server chassis, use No. 2 Phillips screwdriver.

6. Take the clear plastic air duct assembly and place it over the top of the CPU's and DIMMs allowing the DIMMs to protrude through the open slots and the assembly to fit nicely between the chassis walls, power supply metal casing and mid-wall.

7. Install the server top cover and close the fan door:

a. Close the fan door by swinging the door down to the closed position and hearing the latches latch.
b. Place the server top cover on the chassis and slide the top cover toward the front of the server (about 0.5 inches (12.7 mm)) until you hear the top cover release button lock into place.

8. Return the Server to operation.

a. Remove any anti-static measures that were used.
b. Return the server to it's normal operating position within the rack.
c. Re-install the AC power cords and any data cables that were removed.
d. Power on server. Verify that the Power/OK indicator led lights steady on.

How to verify the Internal SAS HBA is working properly

1. "start /SYS" and bring system to ok> prompt and perform a "probe-nvme" to make sure all internal SAS disks are seen.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
     component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
