Replacing the Motherboard
Warning: Be sure to disconnect the power supply before opening the chassis. (Refer to
Chapter 1 for Safety Guidelines.)
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.
9. The following table lists the cables that must be disconnected from the motherboard
to facilitate proper removal:
