Replacing the motherboard
Use the following procedure to install the motherboard in the imagePASS chassis.
To replace the motherboard
1. If you are installing a new motherboard, do the following:
• Remove the security chip from the old motherboard and install it onto the new motherboard (see “Motherboard jumpers”
on page 19 )
• Install the DIMM(s) from the old motherboard onto the new motherboard (see “DIMM” on page 17 )
• Install the CPU from the old motherboard onto the new motherboard (see “CPU and CPU cooling assembly” on page
24 )
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 “Motherboard jumpers” on page 19 ).
NOTE:
As you slide the motherboard into position, lift the connector edge to ensure that the underside of jumper area SPKR1 clears the
nearby screw standoff.
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.
3. Align the mounting holes on the motherboard with the screw holes located in the base of the chassis (see “Motherboard
jumpers” on page 19 ).
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. Figure 13 for the mounting hole locations).
Now you are ready to replace the remaining motherboard components to complete the motherboard installation.
