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 7576 Environmental show Command Examples

In the Cisco 7576, the show environment command 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.

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.

In the Cisco 7576, 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

	RSP(6) Inlet		previously measured at 21C/69F
RSP(6) Hotpoint		previously measured at 29C/84F
RSP(6) Exhaust		previously measured at 25C/77F
+12	Voltage	previously measured at 12.12
+5 Voltage		previously measured at 5.15
-12	Voltage	previously measured at -12.17
+24	Voltage	previously measured at 23.87

In the Cisco 7576, the show environment table command displays the temperature and voltage thresholds for each of the three RSP temperature sensors for each monitored status level: low critical, low warning, high warning, and high critical, which are the same as those listed in Table 2-6and Table 2-7. The slots in which the RSP can be installed are indicated in parentheses (slot 6 and slot 7). Also listed are the shutdown thresholds for the processor boards and power supplies.

Following is sample output of the sh env table command:
