Retention
Bases The processor retention bases support the Pentium III processor(s) mounted on the
SBC. The two (2) retention bases must be installed for either single or dual processors.
The procedure for installing the processor retention bases ( Figure 14
on page 44
) is outlined
in the following table:

Removal
The procedure for removing a Pentium III processor ( Figure 16
on page 46
) is outlined in
the following table:
Step Action
1 Place the processor retention bases on the top surface of the SBC. Align the
screw holes in retention base feet with those in the SBC.
Note: The retention bases are not identical. To aid in proper installation, refer
to the Left (L) and Right (R) designators on the foot of each retention base.
2 Firmly fasten the retention bases to the top surface of the SBC with the four (4)
mounting screws.
Note: The mounting screws are fastened from the bottom surface of the SBC.
Step Action
1 Insert the processor into the retention bases.
Note: The heatsink should be oriented toward the top edge of the SBC.
2 Lower the processor to the processor connector. Carefully push the processor
into the connector.
Note: As the processor is lowered toward the connector, the retention bases
will be pushed outward slightly by the heatsink. As the processor is seated in
the connector, the retention bases will spring back inward to grasp the
heatsink. This secures the processor into the connector.
Step Action
1 Using the thumb and forefinger of one hand, gently push the processor
retention bases outward approximately five degrees (5°) to release the
heatsink.
Note: Do not over-extend the retention bases. This will cause excess stress to
the bases and can damage the equipment.
2 Carefully pull the processor upward to remove it from the connector.
Note: Rock the processor out of the connector by lifting first one end and then
the other. This will prevent excess stress to the retention bases.
3 Lift the processor from the retention bases.
