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:
Router# show env last
