Sun Fire V65x Server Main Board Replacement

Note – Several assemblies must be removed so that the main board can be replaced.
Refer to other sections of this chapter for detailed instructions on how to remove and
replace these assemblies.
To replace the Sun Fire V65x server Main Board, follow these steps:
1. Open the box containing the replacement board and remove one of the two
antistatic pads. You will need this pad in step 17 as an ESD-safe place to place the
old server board.
2. Before removing the cover to work inside the system, observe the previously
mentioned safety guidelines.
3. Remove the cover and bezel from the chassis.
4. Remove the PCI riser board assemblies.
5. Remove the air baffle.
6. Unscrew and remove the blue plastic retention clip that holds down the flex cable
onto the server board.
7. Disconnect the USB ribbon cable from the server board, unthread it from the top
of the fan module, and lay the free end back over the drive bays.
8. Remove the processor air duct.
9. Disconnect the fan cables from the server board and the DIMM fan power cable
from the fan module header and remove the fan module.
10. Remove the DIMM fan and vertical support bars.
11. Disconnect both ends of all remaining cables that connect the main board to other
chassis components (including the power supply).
Note – Some cables may be soldered at one end. Remove only the connectorized
end.
12. Remove the heat sink, processor air dam, and any processors and memory DIMMs
that you wish to use with the new board.
