Installing the Microprocessor Module NOTICE: Ensure that the cam lock is in the fully open position before seating
the microprocessor module. Seating the microprocessor module properly in the
ZIF socket does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an
intermittent connection or permanent damage to the microprocessor and ZIF
socket.
1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the
ZIF socket, and insert the microprocessor module.
NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns
with the triangle on the pin-1 corner of the ZIF socket.
NOTICE: You must position the microprocessor module correctly in the ZIF
socket to avoid permanent damage to the module and the socket.
When the microprocessor module is correctly seated, all four corners are aligned
at the same height. If one or more corners of the module are higher than the
others, the module is not seated correctly.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the
microprocessor module to the system board.
