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 T7-1 Cable kit Replacement

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

NOTE: If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS. A data backup is not a prerequisite but is a wise precaution. For ALL scenarios where an AC power down or AC power cycle is required for a T7-x server, always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

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.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

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.

Replace One or More of the Cables from the Cable Kit

1. Remove the Top Cover of system

2. Open the clear plastic air duct assembly cover by lifting the edge of the cover closest to the rear of the server. The cover can stand in its upright position but perform the next steps if you need to remove the cover:

a. Open the fan cover.
b. Pull open the plastic tabs to release the clear plastic air duct assembly covers hinged edge and remove it from the server.

3. Replace cable(s) by routing them as they were previously and making sure the connections are secure.

Note - Do not over bend the cable(s) and make sure that when you connect the cable(s) you do not bend any pins and the connections are secure.

4. Close the clear plastic air duct assembly cover by rotating it down over the motherboard / two memory risers and then slightly pressing in the two tabs to secure it. See following if you need to reattach the cover:

    a. Open the fan cover.
    b. Align the clear plastic air duct assembly cover on its hinge edge.
    c. Attach the hinged plastic tabs to the server by pulling them open and letting them seat into the holes so that the clear plastic air duct assembly cover can hinge up and down.
    d. Lower the clear plastic air duct assembly cover (making sure the two pairs of side tabs clear the sides of the server).

5. Install the top cover on the system

6. 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 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.
