How to replace a Netra X4250 Faulty Media Bay Assembly.

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES ENGINEER NEED:
Sun X86 Servers

Task Complexity: 2

TIME ESTIMATE: 120 minutes

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

What Action Does the Engineer Need to Take:

1. Verify with customer system is available for power down.
2. Label all cables connected to the server and disconnect.
3. Remove the server from the rack
4. Prepare Antistatic Measures
5. Remove the top cover
6. Removing the Optical Media Drive
7. Removing a Hard Drive

Remove the faulty Media Bay Assembly

1. Disconnect the blue system fan tray assembly cable that connects to the PDB underneath the media bay assembly cables. (This step allows easier access to the media bay assembly cables.)
2. Disconnect media bay assembly cable (top) that connects to the motherboard.
3. Disconnect media bay assembly cable (bottom) that connects to the PDB.
4. Disconnect media bay assembly ribbon cable that connects to the PDB. (You can disconnect this cable from the rear of the media bay assembly or from the PDB after loosening the screws and lifting the assembly out of the chassis.)
5. Loosen captive screws labeled 2 and 3, and remove noncaptive screw labeled 1 closest to the front of the server.
6. Lift the media bay assembly out of the chassis.
7. (Optional) Disconnect and remove the ribbon cable from the PDB.
8. Set the media bay assembly aside on an antistatic mat.

Install the new Media Bay Assembly

1. Remove the replacement media bay assembly from its packaging and place it on an antistatic mat.
2. Move the cables as far out of the way as possible.
3. If disconnected, reconnect the media bay assembly ribbon cable to the PDB. (Arrange the cable where it can be reconnected to the assembly after it is reseated.)
4. Lower the media bay assembly into the chassis until it seats.
5. Tighten the media bay assembly screws.
6. Connect the media bay assembly cable (bottom) that connects to the PDB.
7. Connect the media bay assembly cable (top) that connects to the motherboard.
8. Connect the blue system fan tray assembly cable that connects to the PDB underneath the media bay assembly cables.
9. Installing the Optical Media Drive
10. Installing a Hard Drive
11. Close the bezel.

WHAT ACTION DOES CUSTOMER NEED TO TAKE TO RETURN SYSTEM TO AN OPERATIONAL STATE:
1. Boot up server.
2. Monitor and check messages file (if Solaris or Linux) under usual load by server to check for normal CPU temperatures and operation
3. Use fmadm/fmdump to clear previous faults affecting old system board.
4. Connect to BUI and eventually clear any remaining faulty component, if applicable to system board assembly, clear SEL log and reset SP
