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.
