Time Estimate: 90 minutes

Task Complexity: 2

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: Replace a SPARC T4-4 Server Storage Backplane

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
The server must be fully shut down and the power cords disconnected. A data backup is not a pre-requisite but is a wise precaution.

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:

A) Remove a Storage Backplane

1. Power off the server.

2. Remove all the hard drives from the front of the server for the storage backplane that you want to replace.

NOTE: You have to remove only hard drives 0–3 or drives 4–7, depending on which storage backplane you want to replace. Note the locations of the drives before removing them so that you can install them in their original slots afterwards.

3. Remove the main module from the server.

4. Take the necessary ESD precautions.

5. Locate the storage backplane that you want to remove.

Refer to the following link for details on Locating the Storage Backplanes/Connectors and Cables:

http://docs.oracle.com/cd/E23411_01/html/E23412/z400284c1391401.html#scrolltoc

6. Disconnect the two storage backplane cables from the storage backplane that you want to replace.

a. Lift up on the connectors that secure the data cable to the storage backplane and the motherboard, and remove the data cable from the main module.

b. Lift up on the connectors that secure the power cable to the storage backplane and the motherboard, and remove the power cable from the main module.

7. Lift up on the plastic retaining panel for the storage backplane that you want to remove to disengage the plastic panel from the top of the hard drive assembly.

8. Push the plastic panel toward the rear of the main module, and remove the plastic panel from the main module.

9. Push the top edge of the storage backplane slightly toward the rear of the main module, then lift the storage backplane up and remove it from the main module.

B) Install a Storage Backplane

1. Position the storage backplane in the main module.

2. Lower the storage backplane into place.

3. Slide the plastic retaining panel into place over the storage backplane so that the two notches in the panel slide underneath the two metal mounting studs on the hard drive assembly.

4. Press on the press point on the retaining panel to secure it to the top of the hard drive assembly.

5. Connect the two storage backplane cables to the storage backplane and the motherboard.

a. Connect the data cable to the storage backplane and the motherboard.

b. Connect the power cable to the storage backplane and the motherboard.

6. Insert the main module back into the server.

7. Install the hard drives that you removed back into the main module.

NOTE: Refer to the notes that you took when removing the hard drives to install them back into their original slots.

8. 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 (if only ALOM is supported run "showfaults -v" 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.
