Note
If the system reports temperatures in the critical range, you must manually shut down the router. The
processor cannot shut down the router automatically.

Displaying Environmental Status Reports
Cisco 7100 series VPN routers display 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.
Caution
To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature
conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate
clearance around the sides of the chassis so that cooling air can flow through the chassis interior
unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of other device.
