Temperature Sensor
The Cisco ASR 903 Router has a temperature sensor to detect overtemperature conditions inside the
chassis. The overtemperature detection trips at 75 degrees C +/- 5% with the ambient (inlet) trip point
at 67 degrees C. This condition is reported to the processor as an interrupt, and the software takes action
to generate the appropriate alarms.
