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 2 slot Rear 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 part 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 2 Slot Rear 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.
d. Remove the server top cover.
e. Remove the air baffle from the chassis to allow access to the rear disk backplane.

2. Pull each rear-mounted disk out far enough to disengage it from the rear disk backplane.

Note: It is not necessary to completely remove the storage drives from the server, simply pull them out far enough to disengage them from the disk backplane. If you do remove the storage drives from the server, make a note of their locations so that you can reinstall them in the same locations.

3. Disconnect the cables from the rear disk backplane:

a. Disconnect the two SAS cables from the rear disk backplane.
b. Disconnect the power cable from the rear disk backplane.

4. Using a No. 2 Phillips screwdriver to loosen the two screws that secure the rear disk backplane to the rear drive cage.

5. Lift up the rear disk backplane to release it from the two standoff hooks.

6. Pull the rear disk backplane away from the standoff hooks and remove it from the chassis.

7. Place the rear disk backplane on an antistatic mat.

Install 2 Slot Rear Disk Backplane

1. Lower the rear disk backplane into the server above the power supplies, and position it to engage the two standoff hooks.

2. Use a No. 2 Phillips screwdriver to tighten the two screws that secure the rear disk backplane to the rear drive cage.

3. Reconnect the cables to the rear disk backplane:

a. Reconnect the power cable to the rear disk backplane.
b. Reconnect the two SAS cables to the rear disk backplane.

4. Return the server to operation

a. Place the air baffle over the components on the motherboard.
b. Install the server top cover.
c. Fully insert all drives that you disengaged or removed.
d. Return the server to the normal rack position.
e. Reconnect the power cords to the power supplies, and power on the server.

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.
