REPLACE
THE
MOTHERBOARD
1. If you are installing a new motherboard, do the following:
• Unpack the new motherboard.
• Open the load plate covering the CPU socket (see
) and remove the protective
plastic cover on the CPU socket on the new motherboard. Later, you will transfer the
protective plastic cover to the CPU socket of the old motherboard to protect the circuitry.
• Remove the DIMMs from the old motherboard and install them on the new motherboard
(see
• Remove the CPU and cooling assembly from the old motherboard and install them on the
new motherboard (see
). Make sure that the cable cover (if present) remains on the
cooling assembly fan cable when transferring the cooling assembly to the new
motherboard.
When transferring the CPU to the new motherboard, make sure to use the fresh thermal
compound that came with the new motherboard. For more information about the thermal
compound, see
Do not transfer the BIOS chip from the old motherboard onto the new motherboard. Doing
so can damage the E-8100. BIOS chips are not interchangeable.
2. Install the motherboard in the chassis.
Angle the motherboard so that the back panel connectors on the motherboard fit into the
cutouts in the back of the chassis (see
).
3. Align the mounting holes on the motherboard with the standoffs located in the base of the
chassis.
4. Secure the motherboard to the chassis using the 10 mounting screws that you removed
earlier.
Partially tighten each screw before completing tightening any one screw. Do not overtighten
the screws; doing so could damage traces on the motherboard.
You are ready to complete motherboard installation.

MPORTANT
:
Make sure that the flexible grounding tabs on the cutouts for the network
ports make contact with the outside of the ports. Do not allow the tabs to fold over or
become bent inside the ports. The ports will not function if the tabs are placed
improperly. Take care when lowering the new motherboard into the chassis. Do not
strike the motherboard against the metal standoffs attached to the chassis, as doing so
can damage the components on the underside of the motherboard.
