To monitor the enclosure components, select option “1”

Show Enclosure

Environment Status

by pressing the <1> key.

The screen provides a status list of the internal components such as disk
drives in a specific slot, temperature of the thermal sensors, cooling fan
status, power supply status, and statistics on enclosure “up time.”
