Environmental Monitoring
The system components use environmental monitoring hardware to detect transmit power readings, receive power readings, and
temperature updates.
To receive periodic power updates, enable the enable optic-info-update interval command. The output in the following
example displays the environment status of the RPM.

Displaying Port Extender Environment Information
To display environment details for each port extender, use the show environment pe pe-id command.
Dell#show environment pe pe-id
To display information of hardware components of control bridge only, use the show environment all command.
Dell#show environment all
Display Power Supply Status
To monitor the operational status of a power supply, use the show environment pem command.
Use the command output to verify the operation of installed power supplies. The current operational status (up or down), power supply
type, fan status and speed, and power usage are displayed. A switch power supply is sometimes referred to as a power entry module
(PEM).
