Installing an Additional Processor

NOTE

If you are installing both processors, you may need to remove
the power connector to the system board to have full access to
the processor in primary processor socket (CPU 1).

Installing the Cooling Fan-Heatsink

Once the processor is installed, the cooling fan-heatsink must be installed on top
of the processor. Each processor requires a heatsink, with its cooling fan attached,
and a thermal bonding between the processor and the heatsink, provided with the
white thermal patch. The heatsink is mechanically connected to the processor
socket with both latches, mechanically making contact with processor.

1. Remove the heatsink-fan assembly from the shipping container and ensure

you do not touch the thermal patch on the bottom of the heatsink.

2. Ensure the latches are free and pointing away from the heatsink.

3. Position the heatsink over the second processor and:

a. Tilt or roll it slightly to the rear of the chassis to help engage the hook

latch and then connect the hook latch to the tab. See Figure 6-5.

b. Rotate the heatsink back, placing it squarely on top of the processor and

connect the thumb latch to the tab on the base of the processor socket
on the side shown in Figure 6-5.

The hook latch and thumb latch both hook underneath the tabs
extending from the base of the processor socket base.

c. Ensure the ridge on the bottom of the heatsink rest between the

processor and the edge of the processor socket base.

CAUTION

Ensure you have made good contact with the processor to
avoid thermal overheating. If you have not made good contact
the processor, it will overheat within 20 seconds of power on
and will shut down, possibly causing damage to the processor.

4. Connect the heatsink’s cooling fan connector to the 2nd cooling fan

connector (CPU 2 Fan) on the system board. See Figure 6-1.

CAUTION

Failure to connect the cooling fan to its power connector will
cause the NetServer to shut down with no messages displayed
and possible damage the processor.
