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 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.
l
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

1.2.4 AC Power Supply System
Working principles of the ETP48120-F1 AC power supply system are as follows:
The ETP48120-F1 uses single-phase power input.
The ETP48120-F1 supplies power for AC-DC rectifiers using the system backplane.
The DC output of the AC-DC rectifiers is congregated by the bus and then divided to multiple
power-supplying channels.
The SMU01A monitoring module monitors the operating parameters of the ETP48120-F1 in
real time, analyzes the operating status, and reports alarms.
