Description of the indicators on the PSUs
Indicator Name
Description
OUT
When the indicator is steady green, the PSUs are working properly
and supply stable power.
When the indicator is steady red, the hardware of the PSUs fails or
the device is not supplied with power ranging from -48 V or -60 V
or the input voltage is lower or higher than the normal range.
When the indicator is steady orange, the PSUs fail to communicate
with the main control.
When the indicator is off, the PSUs are switched off or the
hardware of the PSUs is faulty.
IN
When the indicator is steady green, the power input is normal.
When the indicator is off, the device is not supplied with power
ranging from -48 V or -60 V.
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.
