Cleaning the LPOD PS-1.5 Heat Sinks

Follow these steps to clean the LPOD PS-1.5 Heat Sinks:
Step Task
1
Disconnect power from the LPOD.
2 Remove the screws from all four sides of the LPOD as needed – see Figure C-8.
Lift the fan shroud assembly far enough off the chassis to expose the heat sink and access the fan
3
power supply connections – see Figure C-9.
Disconnect each fan power supply by carefully pulling the mated connector components straight apart –
4
see Figure C-10.
Visually inspect the the exposed LPOD heat sink, located on the top of the chassis, for any accumulated
5
debris or blockage that may be obstructing airflow. Use compressed air to clear and clean the heat sink
as needed – see Figure C-11.
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-12
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, making sure to re-install
the four longer screws at their same locations.
8 Reconnect the power source to the LPOD.
A. Be sure to use an appropriate screwdriver, such as the one provided with the
LPOD, to avoid damaging the screws.
B. The length of the four screws indicated in green are longer than those
indicated elsewhere. Be sure to re-install these longer screws at the same
locations.
C. The two screws located behind the waveguide may be difficult to remove
without first removing the waveguide from the chassis.
Do not twist the mated cable connection when disconnecting the cable assemblies.
Be sure to blow between the heat sink fins to remove any foreign object
accumulation.
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.
Torque the screws to 8 ±1 inch lbs.
