Understanding How Environmental Monitoring Works
Environmental monitoring of chassis components provides early-warning indications of possible
component failures, which ensures a safe and reliable system operation and avoids network
interruptions. This section describes the monitoring of these critical system components, which allows
you to identify and rapidly correct hardware-related problems in your system.

Monitoring System Environmental Status

To display system status information, enter the show environment [alarm | cooling | status |
temperature] command. The keywords display the following information:
