C.4 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.
Make sure that you use the correct screwdriver to avoid
damaging the screws
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.
Do not twist the mated cable connection when disconnecting
the cable assemblies.
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.
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-17.
• 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.
Torque the screws to 8 ±1 inch lbs.
8
Reconnect the power source to the LPOD.
