Clean the LPOD PS 1.5 Heat Sinks
To clean the LPOD PS 1.5 Heatsinks, do these steps:
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.
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-9.
4
Disconnect each fan power supply by carefully pulling the mated connector components straight apart –
see Figure C-10.
5
Visually inspect the exposed LPOD heat sink, 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-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 – make sure that you re-
install the four longer screws at their same locations.
8
Reconnect the power source to the LPOD.

Make sure that you use the correct screwdriver to avoid damaging the screws.
The length of the four screws indicated in green are longer than those indicated
elsewhere. Make sure that you re-install these longer screws at the same locations.
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.
Make sure that you 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 that you
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.
