Clean the LPOD PS 2 Heat Sinks

To clean the LPOD PS 2 Heatsinks, do these steps:
Step Task
1 Disconnect the power source from the LPOD.
2 Remove the screws from the sides and end of the LPOD as needed – see Figure C-13.
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.
5 Visually inspect the exposed LPOD 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.
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.
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.
8 Reconnect the power source to the LPOD.
