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.

DISPATCH INSTRUCTIONS

WHAT SKILLS ARE REQUIRED?: SPARC T8-2 Product Training required, to be serviced by qualified Oracle Service personnel, requires the ability to follow steps similar to what is in the Product Service manual.

PROBLEM OVERVIEW: SPARC T8-2 NVMe Cable Replacement

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

Note:

A data backup is not a prerequisite but is a wise precaution.
If the system is still up and functioning, the Customer should perform an orderly and graceful shutdown of the applications and operating system.
Then power off the server and remove the AC power cords from the system. For ALL scenarios where an AC power down or AC power cycle is required for a T8-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

WHAT ACTIONS ARE REQUIRED?:

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.

Replace the NVMe Cable

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 anti-static wrist strap.

2. Remove the Top Cover of system

3. Locate the four NVMe cables that run from the PCIe switch card NVMe connectors (NVMe 0, 1, 2, & 3) in Slot 1 or 2, along side the power supply wall and remind button/divider and into the four NVMe connectors (NVMe 0, 1, 2, & 3)) on the back of the disk backplane.

Note:

When replacing NVMe cables on a SPARC T8-2 you need to replace each one individually.

4. Disconnect the bad NVMe cable from the PCIe Switch card NVMe connector (either NVMe 0, 1, 2, or 3) in Slot 1 or 2 and also from it's corresponding connector (either NVMe 0, 1, 2, or 3) of the disk backplane.

5. Connect the new NVMe cable into the PCIe Switch card NVMe connector (either NVMe 0, 1, 2, or 3) in Slot 1 or 2 and run the cable along side the power supply wall and remind button/divider and into one of the four NVMe connectors (0, 1, 2, or 3) of the disk backplane.

6. Install the Top Cover of system

7. 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.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot system and monitor boot sequence for errors. Test functionality of system:

Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command to verify that the fault has been cleared.
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
Restart software applications per applicable administration guides to resume system operation.
