Cooling Fans
A system contains 8 hot-swappable cooling fans in a 7+1 redundant configuration,
located in the front of the system within a movable fan tray. The fans provide cooling
for the processors, DIMMs, and I/O modules. Each fan has an LED which glows amber
when the fan is failed or faulted. A system can run with one fan faulted.
