B.4 Clean the LPOD PS 1.5 Heat Sinks
Do these steps to clean the LPOD-R PS 1.5 Heat Sinks:
Step Task
1
Disconnect power from the LPOD-R.
2
Remove the screws from all four sides of the LPOD-R as needed – see
Figure B-14.
• Make sure to 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 to 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 B-15.
4
Disconnect each fan power supply by carefully pulling the mated
connector components straight apart – see Figure B-16.
Do not twist the mated cable connection when disconnecting the
cable assemblies.
5
Visually inspect the exposed LPOD-R 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 B-17.
Make 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 B-18.
•
o not twist the mated cable connections when reconnecting
D
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.
