Replacing Parts
To replace the motherboard
1 If you are installing a new motherboard, do the following:
•
Install the DIMM(s) from the old motherboard onto the new motherboard (see page 56 ).
•
Install the CPU from the old motherboard onto the new motherboard (see page 58 ).
When installing these components, make sure that the motherboard is placed on an antistatic surface with some
padding.
Do not transfer the BIOS chip from the old motherboard onto the new motherboard. Doing so can cause the
system to shut down due to incompatibility issues.
2 Angle the motherboard so that the connectors on the motherboard fit into the cutouts in the connector panel of
the chassis, and gently slide the motherboard into the chassis (see Figure 20 on page 51).
3 Align the mounting holes on the motherboard with the screw holes located in the base of the chassis (see Figure 19
on page 49 for the mounting hole locations).
4 Insert the five mounting screws that attach the motherboard to the chassis.
Partially tighten each screw before completely tightening any one screw. Do not overtighten the screws; doing so
could damage traces on the motherboard.
5 Replace the coverplate on the unused DVI port with the two screws you removed earlier (see page 34 ).
6 Replace the power supply (see page 63 ).
Now you are ready to replace the remaining motherboard components to complete the motherboard installation.
Important: Be sure to fit the motherboard Ethernet connectors under the metal grounding tabs in the
cutouts. Failure to position the grounding tabs correctly may result in permanent damage to the motherboard
and power supply.
