Dual Fan Modules
The Secure Firewall 3100 has two fan modules that provide 3 + 1 redundancy. Each fan module has two fans
and each fan has two independent fan rotors. The fan rotors are monitored individually, and this gives 8 fan
rotors per system. When one fan rotor fails, all others spin at maximum speed so that the system continues to
function. The dual fan modules are hot-swappable and installed in the rear of the chassis.
The following figure shows the location of the fan LED on the fan module.
