C.3 Clean the LPOD PS-1.5 Heat Sinks
To clean the LPOD PS-1.5 Heat Sinks, 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.
• Make sure that you use an appropriate screwdriver, such as the one
provided with the LPOD, 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.
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.
Do not twist the mated cable connection when disconnecting the cable
assemblies.
5
Visually inspect the 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.
Make sure that you 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-12.
• 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.
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.
Torque the screws to 8 ±1 inch lbs.
8
Reconnect the power source to the LPOD.
