1. General Information
The PoE (Power Over Ethernet) Switch family provide two 10M/100M/1000M TX ports with PoE
PSE function plus one 10M/100M/1000M TX up-link port with PoE PD function. It allow powered
from PoE power souring equipment (PSE) and deliver power to PoE powered device (PD), which is
compliant with IEEE802.3af and IEEE802.3at standard to receiver and deliver both of Ethernet data
and DC power through the traditional UTP or STP cable. The PoE Switch can extend Ethernet data
and DC power up to 200 meters. This manual will help you install and maintain the PoE switch.
Installation of the PoE switch is very easy and you will begin to operate as soon as you are powered
up.
2. Hardware Description
*LED Indicator
There are 8 LEDs on the PoE switch to indicate the status of power and signal. The following
section describes the functions of each LED indicator.

*Power wiring
The PoE switch family includes 2 models, be used for 2 different ranges of input voltage as,
full range voltage (10 to 57VDC) (P/N: PSE-SW3G11CN)
48VDC typical (40 to 57VDC) (P/N: PSE-SW3G44DN)
All of the PoE switches allow powered by another PoE source (42.5~57VDC) on port 3 (UPLINK).
For PoE operation, make sure your power supply may offer at least 40W for 2x 802.3af PoE port, or
80W for 2x 802.3at PoE port.
If powered on rear terminal, please make sure the input current don’t over 10A, if powered on port
3, make sure the input current don’t over 2Amp.
The port 1&2 will deliver DC power over the Ethernet cable, the connection as:
* Data pair A on line 1 and 2
* Data pair B on line 3 and 6
* Data pair C plus V+ on line 4 and 5
* Data pair D plus V- on line 7 and 8

The port 3 may get DC power over the Ethernet cable, the connection as:
* Data pair A plus V+ /V- on line 1 and 2
* Data pair B plus V-/V+ on line 3 and 6
* Data pair C plus V+/V- on line 4 and 5
* Data pair D plus V-/V+ on line 7 and 8
The terminal block on rear panel should be wiring as:
*For PSE-SW3G44DN
The input voltage must be in the range of 40 to 57VDC if running for 802.3af operation.
The input voltage must be in the range of 50 to 57VDC if running for 802.3at operation.
If the PSE-SW3G44DN is not powered in above designated input voltage, it will only functioning
as an Ethernet switch without PoE output.

*Ethernet Port Wiring
The PoE switch family supports one RJ-45 uplink (port 3 with PoE PD) and two RJ-45 ports (port
1&2 with PoE PSE) with automatic MDI/MDI-X crossover, auto-sense the speed and duplex for
10Base-T, 100Base-TX or 1000Base-T connection. Automatic MDI/MDI-X crossover allows you
to connect to other devices (switches, hubs, or workstations etc.), without regard to using
straight-through or crossover cabling.
Port 1 & 2 provides Power over Ethernet function that delivers DC power through the data pairs C
& D (pair 4,5 and pair7,8) to the PD. Port 3 provides Power Device (PD) function that receive
power from 4 pairs or 2 pairs Ethernet cable.
The following tables describe the wiring diagram of straight-through and crossover cabling. That
crossover cables simply cross-connect the transmit lines at each end to the receive lines at the
opposite end.

Connect an Ethernet cable into any switch port and connect the other side to your
attached device. The Link/Act LED (green or yellow) will light up when the cable is correctly
connected. Refer to the LED Indicator section for descriptions of each LED indicator.
If a port LED is off, go back and check for connectivity problems between that port and the network
device connected.
The maximum cable length for 10/100/1000BaseT with Cat 5 twisted pair cables is typically 100m
(328 ft.).

*PD Port Wiring
Port 1 & 2 provide PoE inject function with maximum 35W ability to power up the powered device
use the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE802.3af Alternative B mode connector assignment. The following
table shows pin assignment of alternative A and B for the Power Source Equipment.
Conductor Alternative A
(MDI-X) Alternative A (MDI) Alternative B (All)
1Negative Vport Positive Vport
2 Negative Vport Positive Vport
3 Positive Vport Negative port
4 Positive Vport
5 Positive Vport
6 Positive Vport NegativenVport
7 Negative Vport
8 Negative Vport
Be sure the twisted pair cable is bound with the standard RJ-45 pin, especially the pin 4, 5, 7 and 8.
If the RJ-45 is bound with the wrong pin number, PoE switch will not recognize the PD and won’t
deliver DC power to PD. The yellow PoE LED will light up when the cable is correctly connected.
Refer to the LED Indicator section for descriptions of each LED indicator. If a port LED is off, go
back and check for connectivity problems between that port and the network device connected.

*Network Application
The PoE Switch can receive power from PoE midspan and provide power to the PD which follows
the IEEE 802.3af/at standard in the network. The PoE Switch can be installed in a more appropriate
position for better performance to extend Ethernet to 200 meters. The following figure is an
example of a network application for PoE Switch.
