11. The new PowerPC 604e microprocessor has an array of connector pins on one
side. The pin array has one missing pin at one corner so that the PowerPC
604e microprocessor can only be installed in one direction. The top of the
processor is keyed with a small dot and a beveled edge that indicates the corner
with the missing pin.
The processor socket is keyed with a matching missing female socket, as shown
in the diagram below. Thus, the PowerPC 604e microprocessor can only be
plugged in one way. Take care to ensure that you have aligned the new
processor correctly.
The PowerPC 604e microprocessor does not require any force when you plug it
into the socket. Take care not to bend or break the connector pins on the
processor.
12. Place the new PowerPC 604e microprocessor into position on the processor
socket. Make sure that all of the pins are seated correctly and that no pin holes
are visible. Lower the upgrade socket lever to lock the processor in place,
making sure that the locking tab is visible.
