Xserve (Late 2006) Logic Board Replacement Instructions 10
Important: Each heat sink is connected to the logic board by a small 2-pin thermal sensor
cable. Be careful not to pull on the wire as you lift each heat sink enough to disconnect the
cable from the logic board. It’s easier to reach the sensor connectors on the logic board if
you start with the right heat sink near the DIMM slots (CPU A).
Slowly lift the heat sink off the processor just far enough that you can reach the sensor cable
connector. You might feel some resistance from the thermal grease that binds the heat sink
to the processor.
Pull on the connector, not the wires, to disconnect the sensor cable from the logic board.
Lift the heat sink straight up and out of the enclosure.
Repeat steps 1 through 4 for the left processor (CPU B) heat sink.
Note: You will need to clean off the old thermal grease from the bottom of each heat sink and
the top of each processor before installing them on the replacement logic board. You will also
need to apply new thermal grease to the tops of the processors. For more information, see
“Replacing the Processors” and “Replacing the Processor Heat Sinks.”
