Replacing the Motherboard
Warning: Be sure to disconnect the power supply before opening the
chassis.
Removal Procedure
1. Lay the chassis on a flat surface.
2. Remove the top cover of the unit.
3. Remove all fans (6) and air shrouds from the chassis.
4. Remove the foam sealing from underneath the 4 front fans noting
the location of the slots in the foam for proper cable routing.
5. Using a marking pen, place a mark on the heat sink on the front or
rear to denote its placement. This will help keep the orientation of
the processor and the heatsink due to the thermal compound when
the two components are separated. It will provide a better thermal
connection when the two components are reinstalled.
6. Remove the 4 screws holding the CPU heat sink and carefully
remove.
Caution: The heat sink may be adhered to the top of the CPU due to the
thermal compound applied during assembly.
7. Raise the locking lever on the socket holding the CPU and
carefully remove. Set aside on antistatic foam.
8. Remove the RAM sticks from their sockets. Set aside on antistatic
foam or antistatic pouch.
