When the system power is on, the blower must be operational. If the system detects that the blower has 
failed or is failing, it will display a warning message on the console screen. The entire system will shut 
down when the voltage at the hotpoint sensor (center of the RSP) reaches a predetermined value. 

In the following example, the system has detected an out-of-tolerance blower, which it interprets as a 
blower failure.

%ENVM-2-FAN: Blower has failed.

When the temperature reaches a critical level, the system will display the following message on the 
console screen and in the show environment command display when the system restarts:

Queued messages:

%ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown

In the Cisco 7513 and Cisco 7513-MX, 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 status range. 

The current monitor circuits of the 7513 power supply are only accurate at high power levels. They are 
there to prevent over-configuration and serve no purpose at low power levels. If the system is not 
operating above 70% power, the measurement results are not accurate. Above 70%, the measurements 
have the degree of accuracy needed to prevent the insertion of too many line cards into the system.

Following is sample output of the show env command:
