The router provides a robust environment-monitoring system with several sensors that monitor the system temperatures. The following are some of the key functions of the environmental monitoring system:

• Monitoring temperature of CPUs and Motherboard

• Recording abnormal events and generating notifications

• Monitoring Simple Network Management Protocol (SNMP) traps

• Generating and collecting Onboard Failure Logging (OBFL) data

• Sending call home event notifications

• Logging system error messages

• Displaying present settings and status

Monitoring and reporting functions allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation.

• Environmental Monitoring Functions

• Environmental Reporting Functions

Environmental monitoring functions use sensors to monitor the temperature of the cooling air as it moves through the chassis.

The router is expected to meet the following environmental operating conditions

• Operating Temperature: -40°F to 140°F (-40°C to 60°C)

• Operating Humidity: 5% to 95% relative humidity (non-condensing)

• Operating Altitude: Up to 10,000 ft (3048 m)

Note	Refer to the Cisco Catalyst IR8340 Rugged Series Router Harware Installation Guide for restricted ranges of the environmental operating conditions for exceptions which is specially applicable for harsh industrial deployments.

The following table displays the levels of status conditions used by the environmental monitoring system.

The environmental monitoring system sends system messages to the console, for example, when the conditions described here are met:

Warnings :
--------
For all the temperature sensors (name starting with “Temp:”) above,
the critical warning threshold is 100C (100C and higher)
the warning threshold is 80C (range from 80C to 99C)
the low warning threshold is 1C (range from -inf to 1C).
 
For all voltage sensors (names starting with "V:"),
the high warning threshold starts at that voltage +10%. (voltage + 10% is warning)
the low warning threshold starts at the voltage -10%. (voltage - 10% is warning)

You can retrieve and display environmental status reports using the following commands:

• show diag all eeprom

• show environment

• show environment all

• show inventory

• show platform

• show platform diag

• show platform software status control-processor

• show diag slot R0 eeprom detail

• show version

• show power

These commands show the current values of parameters such as temperature and voltage.

The environmental monitoring system updates the values of these parameters every 60 seconds.
