C.4 Clean the SPOD PS 2 Heat Sinks
To clean the SPOD PS 2 Heat Sink:, do these steps:
Step Task
1 Disconnect the power source from the SPOD.
2 Remove the screws from the sides and end of the SPOD as needed – see Figure C-13.
Be sure to use an appropriate screwdriver, such as the one provided with
the SPOD, to avoid damaging the screws
3 Lift the fan shroud assembly far enough off the chassis to expose the heat sink and access the fan
power supply connections – see Figure C-14.
4 Disconnect each fan power supply by carefully pulling the mated connector components straight apart
– see Figure C-15.
Do not twist the mated cable connection when disconnecting the cable
assemblies.
5 Visually inspect the the exposed SPOD heat sinks, located on the top of the chassis, for any
accumulated debris or blockage that may be obstructing airflow. Use compressed air to clear and
clean the heat sink as needed – see Figure C-16.
Be sure to blow between the heat sink fins to remove any foreign object
accumulation.
6 Reconnect each fan power supply. First, align the male and female connector’s tabs. Then, push the
connectors together until the connection locks – see Figure C-17.
• Do not twist the mated cable connections when reconnecting the fan
power supplies.
• The fan power supply cables are labeled Fan 1 and Fan 2. Make sure to
connect the chassis Fan 1 cable to the fan shroud Fan 1 cable, and the
chassis Fan 2 cable to the fan shroud Fan 2 cable.
7 Re-install the fan shroud onto the chassis – take care to keep the fan power supply cables clear of the
fan and heat sink surfaces. Then, re-install all screws as described in Step 2.
Torque the screws to 8 ±1 inch lbs.
8 Reconnect the power source to the SPOD.
