Description
The power cooling module (PCM) is an integrated power supply and cooling
fan. One PCM can supply enough power for the enclosure. Each PCM must
draw power from different mains. If one main fails, operation of the other PCM
continues.
This power connection requires a power cable to be attached between the
power supply and an independent electrical source capable of supporting the
entire power load of the enclosure and controlled by its own circuit breaker.
