The redundant cooling by the fans in the server enables continued operation if one rotor of a fan fails.

When the system is powered off but still plugged in to AC power, fans 1 and 2 may continue to spin at a much lower speed. This is the system design to provide proper cooling.

Electrical input​

Electrical input
