Safety Precautions
•Customer equipment connected to the GE electrical ports of outdoor PIs must have surge protection
capabilities. If customer equipment does not have surge protection capabilities, PIs must be installed indoors.
•Do not touch the connector terminals or pins of P&E cables or DC power cables. Instead, hold the insulation
parts of the cables.
•Prevent conductors or hands from touching the terminals or pins in the P&E ports and DC input/output ports on
PIs.
•Before installing a DC input power cable on a PI, identify the positive and negative ends of the cable. Ensure
that the cable is connected correctly. Install a circuit breaker at the negative end of the external power supply
device to prevent circuit loops from damaging the power cable and PI.
•Before installing a DC output power cable on a PI, identify the positive and negative ends of the cable. Ensure
that the cable is connected correctly. Do not connect the output port of the external power supply device to the
DC output port of the PI.
•Do not connect the output port of the external power supply device to a P&E port of the PI.
•Do not install any cables when devices are powered on.
•When making and installing cables, avoid dropping any metal scraps or other miscellaneous objects into a PI.
•After setting DIP switches, switch off the power supply. After waiting for 6 seconds, switch on the power supply
again.

AAppearance and Ports
The RTN PI-DC B20 is a full-outdoor PI with high power. It uses DC power input and transmits GE electrical signals and -48 V power signals to the full-outdoor RTN 300 equipment through an
outdoor network cable.
Product Overview
CIndicator Status Description
Indicator Status Meaning
POWER Steady green Power is being supplied.
Off No power is supplied.
DC OUT Steady green The PI uses DC power output, and the output is normal.
Off The DC output port does not
output any power.
P&E OUT
Steady green The PI uses P&E output, and the
output is normal.
Blinks green In PSE-PD mode, the PI is in the
handshake state.
Off
The P&E port does not output any
power.
BPort Description
The pin assignments for Ethernet service signals in the ports GE1 and GE2 are consistent with those in
the ports P&E1 and P&E2. These ports all support the MDI, MDI-X, and auto-MDI/MDI-X modes.
The P&E1 OUT and P&E2 OUT indicators inside a PI indicate the output status of the corresponding
ports. Their meanings are the same as the meaning of the P&E OUT indicator on the side of the PI.

Whether the P&E ports use MDI or MDI-X mode to transmit Ethernet service signals does not affect the
pin assignments for power signals.

Principles and Application Scenarios
Product Overview
The RTN PI-DC B20 receives one channel of DC power signals and two channels of GE service signals.
After the PI receives DC power signals, the DC-DC processing module increases the voltage to -51.0 V.
If DC output is required, set the corresponding DIP switch to select the DC output mode. Then, the PI outputs the DC power
signals with the voltage increased to the DC output port.
If P&E output is required, set the corresponding DIP switch to select the P&E output mode. Then, the signal coupling module
couples DC power signals and GE service signals into P&E signals and outputs the P&E signals to the P&E port.
The frequencies of DC power signals and GE service signals do not interfere with each other. Therefore, the two types of
signals can be transmitted over the same twisted pair.

•The PI only couples GE signals and power signals, but does not regenerate or strengthen GE signals. Therefore, the
network cable between the UNI-side device and the powered device must not be longer than 100 m.
•The maximum distance between the PI and the powered device varies depending on the power of the powered device.

outdoor network cable to connect the P&E2 interface of the PI.
The network element can be accessed by linking the notebook to
the GE2 interface for maintenance.
For the RTN 320/380H, a network management cable can be
connected to the NMS/GE multifunctional port. Note that network
management cables cannot be connected to both the NMS/GE
multifunctional port and the independent NMS port.
