63 Installation and Service Guide
Replacing Parts
• Do not remove the motherboard replacement dongle while transferring options to the new motherboard.
Removing the motherboard replacement dongle prematurely will corrupt the dongle and possibly damage the
motherboard. If either become corrupted, you must contact your authorized service/support center and order a
new replacement motherboard kit.
To 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 page 70) 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 DIMM from the old motherboard and install it on the new motherboard (see page 67).
• Remove the CPU and cooling assembly from the old motherboard and install them on the new motherboard
(see page 70). Make sure that the cable cover (if present) remains on the cooling assembly fan cable when
transferring the cooling assembly to the new motherboard.
2 Install the motherboard in the chassis.
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 page 61).
Note: As you slide the motherboard into position, lift the connector edge to ensure that the underside of jumper area
PCIEX8 clears the nearby screw standoff.
3 Align the mounting holes on the motherboard with the screw holes located in the base of the chassis (see page 59)
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 over-tight the screws; doing so
could damage traces on the motherboard.
Now you are ready to replace the remaining motherboard components to complete the motherboard installation.
Important: 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
page 71.
Important: Do not transfer the BIOS chip from the old motherboard onto the new motherboard. Doing so
can damage the E-35A. BIOS chips are not interchangeable.
