Replace the Fan Assembly

The fans used by the HPOD are designed for long life even in harsh environments. Still, they are
mechanical devices subject to wear and may need replacement after several years. In dusty
environments, their removal facilitates clearing the heat sink of accumulated dust.

Step Task

2 Loosen the six captive fasteners where shown in Figure C-2.
