PROBLEM OVERVIEW: System Board failure

OBTAIN CUSTOMER ACCEPTANCE

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

A data backup is not a pre-requisite but is a wise precaution.
The customer should conduct an orderly software system shutdown.

 WHAT ACTION DOES THE FIELD ENGINEER/CUSTOMER ADMINISTRATOR NEED TO TAKE:

Replacing the System Board

Caution – The procedure below is for the attention of qualified service engineers only. Before touching or replacing any components inside the server, disconnect all
cables. Always place the server on a grounded ESD pad and wear a properly grounded antistatic wrist strap.

To perform the steps in this section, you need a 5mm nut-spinner to remove and replace the SCSI pillars on the rear of the chassis.

Removing the Old System Board
1. Open the server. Make sure all external cables are disconnected and pay particular attention to the information about how to prevent electro-static discharge from your body from damaging the components of the server.

2. With the server open and seated on top of an ESD pad, and with a properly grounded antistatic wrist strap on your wrist, do the following:

a. Disconnect all power supply cables from the system board.
b. Disconnect the DVD or CD-ROM ribbon cable from the system board.
c. Disconnect the memory card reader cable from the system board.

3. Remove the server’s front bezel.

4. Remove the hard disk drives in the server.

5. Remove the PCI card if you have one installed.

6. Remove the DIMMs from their slots.

7. Remove the rear fan subassembly.

8. Unplug the power cable for Fan 3 and undo the two screws that fasten the ducting assembly to the chassis.

9. Pull the fan and ducting assembly away from the chassis.

10. Unscrew the system board protection/support block (between the PSU and Hard Disk Drive bay 1) and slide it back as far as the PSU.

11. Unscrew and remove the PCI card slide retainer.

12. Unscrew all system board fixing screws.

13. Unscrew the SCSI pillars on the back panel.

14. Slide the system board towards the front of the chassis so that the SCSI, Ethernet and Serial connectors come free from the chassis.

15. Carefully lift out the system board.

Installing the New System Board

Note – The system board contains a jumper (JP8) that identifies the hardware to the system software as either a Sun Fire V120 or a Netra 120. The factory default setting for JP8 on FRU replacement system boards (375-3064 and 375-3065) identifies them as Sun Fire V120s. Before installing a new system board, make sure that the setting for JP8 is correct for the model of system you are installing it into.

1. Check that the setting for jumper JP8 on the new system board is correct for the model of server you are installing it into.

2. Insert the new system board at an angle, and locate it so that the SCSI, Ethernet, and serial connectors are firmly positioned in their slots at the rear of the chassis.

3. Now position the system board on the alignment stand-off between the PSU fan and hard disk drive bay 1.

4. Insert the SCSI pillars and replace their screws loosely.

5. Insert all system board fixing screws loosely. Do not put any screws in the holes for the PCI card slide retainer.

6. Tighten up the SCSI pillars, then tighten all the other screws.

7. Replace the PCI card slide retainer, DIMMs that you removed from the OLD system board, rear fan assembly, Fan 3 assembly, PCI cards

8. Slide the system board protection/support block forward until it engages with the system board. Tighten the screw to fix the block to the chassis.

9. Reconnect all system board cables.

10. Replace the server’s cover and tighten the captive screw and replace the front bezel.

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN the SYSTEM TO AN OPERATIONAL STATE:

Restart software applications per applicable administration guides to resume system operation.
