DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:

Time Estimate: 150 minutes

TASK COMPLEXITY: 1

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: disk backplane failure

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

Customer should shut down system (shut the operating system down gracefully, using "init 5") and then power down the server. A data backup is not a pre-requisite but is a wise precaution.


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Remove the Hard Disk Backplane

1. Remove the server from the rack.

2. Remove the top cover.

3. Remove the hard drive cage.

   * Remove all hard drives and the DVD/USB.
   Note - Make a note of the drive locations before removing them. You will need to install the hard drives in the same locations when reassembling the system.
   * Remove the No. 2 Phillips screws that secure the hard drive cage to the chassis. Two screws secure the disk cage to each side of the chassis
   * Remove the four center fan modules to provide easier access to the three backplane connectors.Disconnect the three cables from the backplane.

1. Deflect the release tab on the fan deck to expose the data cables.
2. Make a note of the cable/connector configuration to ensure that the cables will be reconnected to the right connectors.

   Caution - The data cables are delicate. Use great care when sliding the disk cage in or out of the chassis that it does not rub against the cables.

1. Slide the hard drive cage forward to disengage the backplane from the connector board.
2. Lift the hard drive cage up and out of the chassis.
3. Set the hard drive cage on an antistatic mat.

4. Remove the four No. 2 Phillips screws securing the backplane to the hard drive cage.

Tip - Place the hard drive cage upright on its front face for easier access to the backplane screws.

5. Remove the plastic backplane retention bracket from the backplane and set it aside for use when installing the backplane.

Tip - Make note of how the alignment clip is installed so you can position it properly when installing the backplane.

6. Slide the backplane down and off the hard drive cage retention hooks.

7. Place the hard drive backplane on an antistatic mat.


Install the Hard Drive Backplane

1. Slide the backplane under the retention hooks on the hard drive cage.

2. Install the four No. 2 Phillips screws and tighten just enough to hold the backplane against the hard drive cage.

Tip - You will complete the alignment of the backplane in the next step, so the screws cannot be too tight during that step.

3. With the backplane attached to the disk cage, push up against the bottom edge of the backplane and insert the retention bracket.

4. While keeping upward pressure on the backplane, press the retention bracket against the backplane, with the pins in line with the slots just above the hooks.

5. Complete tightening the four screws that secure the backplane to the disk cage.

6. Install the hard drive cage.

   * Position the hard drive cage in the chassis, over the chassis standoffs.

   Caution - The data cables are delicate. Use great care when sliding the disk cage in or out of the chassis that it does not rub against the cables.

   * Slide the hard drive cage back until the hard drive backplane engages with the connector board.

   Caution - Use care when installing the hard drive cage. Be certain that the hard drive cage is aligned with the base of the chassis before sliding the cage back.

   * Connect the backplane data cables.

   * Reinstall the No. 2 Phillips screws that secure the hard drive cage to the chassis.

     - Two screws secure the disk cage to each side of the chassis.

7. Install the top cover.

8. Put the server into the rack.

9. Install the hard drives in the same locations as they occupied before the replacement.

10. Install the DVD/USB module.


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.
