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 power supply modules in real time, and supports
real-time reporting of power supply alarms.
You do not need to connect protection ground cables to the power supply modules, but
the protection ground cable for the chassis must be properly grounded. DC power cables
include a -48 V power cable and an 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.
