I. Functions
The Eudemon200 firewall is configured with six fans that are separated into three
groups. When all these fans are working normally, the operating temperature of the
system can be maintained in the range of 0 to 55
the operation of other fans, the system will still be able to operate in the normal
temperature. The rotating speed of the fans is controlled by the RPU and is in the range
of 50% to 100%. The FAN controller uses two parameters, i.e., low-temperature
threshold and high-temperature threshold to control the rotation speed of the fans, with
the former corresponding to 100% rotating speed and the latter corresponding to 50%
rotating speed. The system will send out rotation stop alarm signals in case any fan fails.
The alarm and state LEDs of FAN are located on the RPU front panel.
