5.Unlock the processor-locking mechanism using the special processor tool (P/N 5069-5441), or equivalent 2.5 mm hex tool, shipped with your replacement processor assembly. Insert the tool into the lock and rotate the special processor tool 180 degrees counterclockwise. Verify that the processor-locking mechanism is rotated into the unlocked position.

CAUTION: The zero insertion force (ZIF) socket for the processor is locked and unlocked by 1/2 of a full turn of the 2.5 mm hex tool. The counterclockwise 180 degree rotation (1/2 turn) unlocks the socket. A clockwise 180 degree rotation locks the socket. Attempting to turn the locking mechanism more that 180 degrees can severely damage the socket.
