If the air temperature exceeds a defined threshold, the system controller displays warning messages on
the console terminal and, if the temperature exceeds the shutdown threshold, it shuts down the system.
The system stores the present parameter measurements for both temperature and DC voltage in NVRAM
so that you can retrieve them later as a report of the last shutdown parameters.
The power supplies monitor internal power supply temperature and voltages. A power supply is either
within tolerance (normal) or out of tolerance (critical), as shown in
temperature or voltage reaches a critical level, the power supply shuts down without any interaction with
the system processor.

Reporting Functions

The Cisco uBR7200 series router displays warning messages on the console if chassis
interface-monitored parameters exceed a desired threshold. You can also retrieve and display
environmental status reports with the show environment, show environment all, show environment
last, and show environment table commands. Parameters are measured and reporting functions are
updated every 60 seconds. A brief description of each of these commands follows.
