Clean the LPOD PS 1 Heat Sinks
To clean the LPOD PS 1 Heatsinks, do these steps:
Step Task
1
Disconnect power from the LPOD.
2
Remove the eight screws – four on either side of the fan shroud – see Figure C-3.
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 sinks and access the fan’s
power supply connection – see Figure C-4.
4
Disconnect the fan power supply. First, depress the connector’s locking mechanism, and then pull apart
the mated components – see Figure C-5.
5
Visually inspect the exposed LPOD heat sinks, located on the top and either side of the chassis, for any
accumulated debris or blockage that may be obstructing airflow. Use compressed air to clear and clean
the heat sinks as needed – see Figure C-6.
Make sure that you blow between the heat sink fins to remove any foreign object
accumulation.
6
Reconnect the fan power supply by pressing the male and female connectors together until the locking
mechanism snaps and locks – see Figure C-7.
7
Re-install the fan shroud onto the chassis – make sure that you keep the fan power supply cable clear of
the fan and heat sink surfaces. Then, re-install the eight screws as described in Step 2.
Torque the screws to 11 ±2 inch lbs.
8
Reconnect the power source to the LPOD.
