Chapter 10 Environmental Monitoring and Power Management
About Environmental Monitoring
Environmental monitoring of chassis components provides early warning indications of possible
component failure. This warning helps you to ensure the safe and reliable operation of your system and
avoid network interruptions.
This section describes how to monitor critical system components so that you can identify and rapidly
correct hardware-related problems.
Using CLI Commands to Monitor your Environment
Use the show environment CLI command to monitor the system. This section gives a basic overview of
the command and keywords you need.
Enter the show environment [alarm | status | temperature] command to display system status
information. Keyword descriptions are listed in Table 10-1.
Displaying Environment Conditions
This section includes these topics:
• Conditions on Supervisor Engines II-Plus to V-10GE, page 10-2
• Conditions on Supervisor Engine 6-E and Supervisor Engine 6L-E, page 10-3
Conditions on Supervisor Engines II-Plus to V-10GE
The following example shows how to display the environment condition on
Supervisor Engines II-Plus to V-10GEs. The output indicates that the power supplies differ. The switch
uses only one power supply and disables the other.
