2.2 Fan Modules
DarkStar systems ship with two fan modules. In the event of a fan module failure, one fan module is sufficient to adequately
cool the system under normal operating conditions. Fan modules are hot swappable and can be replaced and configured
while the system is running. Each physical fan module contains two individual fan blowers.
