B.3 Clean the LPOD-R PS 1 Heat Sinks
Do these steps to clean the LPOD-R PS 1 Heat Sinks:
Step Task
1
Disconnect power from the LPOD-R.
2
Remove the eight screws – four on either side of the fan shroud – see
Figure B-9.
Make sure to 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 B-10.
4
Disconnect the fan power supply. First, depress the connector's locking
mechanism, and then pull apart the mated components – see Figure B-11.
5
Visually inspect the exposed LPOD-R 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 B-12.
Make sure to 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 B-13.
7
Re-install the fan shroud onto the chassis – make sure to 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-R.
