Notes on DC power monitoring:
The DC power monitoring channel can implement real-time monitoring on power supply.
In addition, the DC power monitoring channel allows you to query the manufacturing ID,
input voltage, and temperature of the PSUs in real time, and supports real-time reporting
of power supply alarms.

Notes on the configuration of DC power cables:
You do not need to connect protection ground cables to the PSUs, but the protection ground
cable for the chassis must be properly grounded. DC power cables include a -48 V power
cable and a return (RTN) ground cable. The required cable length depends on the distance
between the cabinet and the power distribution cabinet for the device. The DC power cables
need to be prepared according to the required lengths on site. For details about DC power
cables, see
