Fan modules
The Pikes Peak DAE has three hot-swappable managed system fans at the rear in a
redundant 2-plus-1 configuration. Logic in the DAE will gracefully shut down the DAE
if the heat becomes too high after a fan failure. A failed fan must be left in place until
the fan replacement service call. Each fan has an amber fault LED. The fans are
labeled A, B, and C from right to left.
