Environmental Monitoring Temperature Sensor - Cisco MWR 1941-DC - 1941 Mobile Wireless Router Hardware Installation Manual

Chapter 1 Overview of the Cisco MWR 1941-DC Router

Environmental Monitoring Temperature Sensor

The MWR 1941-DC router has a temperature sensor to detect over-temperature conditions inside the
chassis. The over-temperature detection trips at 75°C +/- 5%. This condition is reported to the processor
as an interrupt and software then takes action on this interrupt to generate the appropriate alarming. If
the router reaches a temperature of 90°C, the power supply will cycle to prevent the box from exceeding
that temperature in a powered up state.
