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.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER NEED:
SPARC S7-2L 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.

Time Estimate: 60 minutes

TASK COMPLEXITY: 2

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: SPARC S7-2L (between the Internal SAS HBA and the 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 SAS Cables (between the Internal SAS HBA 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. To disconnect each SAS cable from the disk backplane, press the latch on the cable connectors and pull the connectors out.

6. Disconnect the SAS cables from the internal host bus adapter (HBA) located in PCIe slot 7:

a. Disconnect the SAS storage drive (HDD) cables from the internal HBA card installed in PCIe slot 7. This can be done by releasing the connector catch located where the SAS cable plugs into the HBA.
b. Carefully remove the SAS cables by sliding them through the mid-wall opening and out toward the disk backplane.

Install Internal SAS Cables (between the Internal SAS HBA and the Disk Backplane)

1. Carefully guide SAS cables (HBA end) between the fan module and side of chassis and through the cable hole in the mid-wall.

2. Install the SAS cables into the disk backplane.

3. Install all of the server fan modules.

4. Reconnect the SAS cables to the internal HBA card making sure they are latched in securely.

5. 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.

6. 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.

12. 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-scsi-all" 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.
