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:
• alarm—Displays environmental alarms.
– status—Displays alarm status.
– thresholds—Displays alarm thresholds.
• cooling—Displays fan tray status, chassis cooling capacity, ambient temperature, and per-slot
cooling capacity.
• status—Displays field-replaceable unit (FRU) operational status and power and temperature
information.
• temperature—Displays FRU temperature information.
To view the system status information, enter the show environment command:
