Environmental Monitoring Temperature Sensor

The Cisco ASR 901 10G router has a temperature sensor to detect overtemperature conditions inside the chassis. The overtemperature detection trips at 70°C. This condition is reported to the processor as an interrupt, where the software generates the appropriate alarms. If the router reaches a temperature of 90°C, the power supply cycles itself to prevent the router from exceeding the maximum temperature while being powered up.

Note Auxiliary port is not supported.
