Environmental Monitoring Temperature Sensor; System Specifications - Cisco MWR 1941-DC-A Hardware Installation Manual

Chapter 1 Product Overview
The Cisco MWR 1941-DC-A router uses a small, three-wire connector (Phoenix Contact part number
1756272) for input to the power supply. The connector ships in the accessory kit.
With the connector installed in the chassis, the pins from top to bottom are 1, 2, and 3, respectively.

Environmental Monitoring Temperature Sensor

The Cisco MWR 1941-DC-A router has a temperature sensor to detect overtemperature conditions
inside the chassis. The overtemperature detection trips at 75°C +/- 5%. This condition is reported to the
processor as an interrupt, where software takes action to generate the appropriate alarms. If the router
reaches a temperature of 90°C, the power supply will cycle to prevent the router from exceeding that
temperature while being powered up.
