Chapter 2 Preparing for Installation

Environmental Monitoring and Reporting Overview for the Cisco 7500 Series

Cisco 7500 Series Environmental Reports

The system displays warning messages on the console if chassis interface-monitored parameters exceed

a desired threshold or if a blower failure occurs. 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.

Note All temperature ranges and values described in this section are subject to change.

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. Obstructing or blocking the air vents will restrict the airflow and can cause the internal

chassis temperature to exceed acceptable limits.

The following sections include the environmental reporting and fan or blower functions for the Cisco

7500 series routers:
