Chapter 1 Overview of the Cisco MWR 1941-DC Router Environmental Monitoring Temperature Sensor 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.

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.

Cisco MWR 1941-DC Router Interface Numbering
Each network interface on a Cisco MWR 1941-DC router is identified by a slot number and a port
number.
Figure 1-5
shows an example of interface numbering on a Cisco MWR 1941-DC router with the
following configuration for a Cell Site DCN implementation:
•
A VWIC in two of the three VWIC slots
•
A 4-port asynchronous/synchronous serial network module in slot 1
•
Two built-in Fast Ethernet interfaces
