Remove the four fan cover screws – see Figure B-2.
Be sure to use an appropriate screwdriver, such as the one provided with the LPOD-R,
to avoid damaging the screws.

Visually inspect the exposed LPOD-R heat sinks 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-5.
Be sure to blow between the heat sink fins to remove any foreign object accumulation.
6 CAUTION – Reseat the fan assembly in the LPOD-R chassis. Be sure to keep the fan
power supply wiring clear of the fan and heat sink surfaces. See Figure B-6.

Re-install the fan cover plate onto the chassis – see Figure B-7 – be sure to keep the fan power
supply wiring clear of the cover plate surfaces. Then, re-install the four cover screws as described
in Step 2.
Torque the screws to 11 ±2 inch lbs.
