Cisco 7100 Series VPN Router Installation and Configuration Guide

Chapter 1 Overview

Functional Overview

Note For more information on troubleshooting an overtemperature condition in your router, see the

“Troubleshooting the Cooling Subsystem” section on page 5-6.

Table 1-17 lists the typical temperature thresholds for each network processor type, and Table 1-18 lists

the power thresholds for the normal, warning, and critical (power supply-monitored) levels.

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.
