Environmental and Power Management

The Cisco 819 integrated services routers are equipped with sensors in the router body for monitoring the environment temperature and logging the temperature every 30 seconds.There are four sensors located on the four corners of the router chassis. There is an additonal System Ambient sensor and a 3G sensor.

The corner sensors display the following message:

•Error message on the console—When the temperature ranges are outside the set temperature thresholds, the monitor displays an error message. Different temperature ranges are set for different SKUs of the router:

–Cisco 819G (non-hardened): 0 to 60 degrees celcius

–Cisco 819HG (hardened): –25 to 75 degrees celcius

•SNMP Traps—syslog messages are created when the temperature is outside the specified range.

•Server “call home” feature—The server callhome feature is already enabled to call Cisco TAC in the event of very high or low temperatures.

In addition to the corner sensors, the System Ambient and 3G sensors also log the temperature every 30 seconds onto bootflash memory.

Any time the temperature is above the high threshold, or lower than the low threshold, the temperature information will be saved in non-volatile memory region and is also displayed as part of this output.

Use the show environment command to check the temperature of the router. You can also use this command to display the power usage and the power consumption of the unit at the end.

The following is a sample output for the show environment command:
