Shutdown temperature source is 'hotpoint' slot3 (requested slot2)
+12V measured at 11.84
+5V measured at 5.05
-12V measured at -11.84
+24V measured at 23.78
+2.5 reference is 2.46
PS1 +5V Current measured at 42.35 A (capacity 200 A)
PS1 +12V Current measured at 6.86 A (capacity 35 A)
PS1 -12V Current measured at 0.55 A (capacity
3 A)
PS1 output is 296 W
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
Cisco 7513 and Cisco 7513-MX Environmental show Command Examples
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.
Note
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:
Router# show env
