Environmental Monitoring Temperature Sensor
Environmental Monitoring Temperature Sensor
The Cisco ASR 901 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 85°C, the power supply cycles itself to prevent the router from exceeding the maximum temperature while being powered up.

Router Interface Numbering
Each network interface on a Cisco ASR 901 router is identified by a slot number and a port number, explained in this sequence:
•Logical slot numbers starts from 0 for all
•Logical interface numbering for T1/E1 ports on the TDM interface module runs from 0/0 through 0/15. Ports are numbered bottom to top, left to right.
