Threshold values for the operating temperature

The device determines the speed of the fans autonomously. The speed cannot be set from the outside. The table below shows the temperature threshold values which result in the fan speed increasing.

By default the threshold value for a warning is 10 degrees Celsius lower than the critical threshold value. As soon as the temperature exceeds the high-limit temperature threshold (TB), the fan operates at maximum speed. When a lower threshold value is fallen below, the fan speed is reduced.

Model	Low-limit temperature TA (°C)	High-limit temperature TB (°C)	Critical (shutdown) temperature TC (°C)
IXC 6450-24	66	71	83
IXC 6450-48	64	69	76
