Cisco Systems 7513 manual Environmental Reports, Router# show env last

Product Overview

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. 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. When viewing the chassis from the interface processor end, the airflow intake vent is on the front of the chassis (below the card cage), and the exhaust vent in on the front of the chassis (behind the lower front panel). Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded. Obstructing or blocking the chassis sides will restrict the airflow and can cause the internal chassis temperature to exceed acceptable limits.

The show environment command display reports the current environmental status of the system. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within Normal range. Following is sample output of the show env command:

Router# show env

All measured values are normal

If the environmental status is not normal, the system reports the worst-case status level in the last line of the display.

The show environment last command retrieves and displays the NVRAM log showing the reason for the last shutdown (if the shutdown was related to voltage or temperature) and the environmental status at that time. Air temperature is measured and displayed; the DC voltages supplied by the power supply are also displayed. Following is sample output of the show env last command:
