1. General Information
The PoE (Power Over Ethernet) Switch 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 ,IEEE802.3at and IEEE802.3bt 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 PSE-SW3B44D4 is IEE802.3bt PoE switch, for PoE operation, make sure your power supply
may offer at least 40W for 2X 802.3af PoE ports, or 75W for 2X802.3at PoE ports, or 185W for 4X
802.3bt PoE ports. The input voltage must in the range of 44V to 57VDC if using for 802.3af
operation. The input voltage must in the range of 50V to 57VDC if using for 802.3at & 802.3bt
type 3 operation. The input voltage must in the range of 53V to 57VDC if using for 802.3bt type 4
operation.
The PoE switch PSE-SW3B44D4 allow powered by another PoE source on UPLINK as a PoE
repeater or extender.
If powered via the rear terminal, please make sure the input current is not over 10A. If powered on
UPLINK, make sure the input current is not over 2Amp.
The port 1&2 will deliver DC power over the Ethernet cable, the connection as:
* Data pair A plus V- on line 1 and 2
* Data pair B plus V+ 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 UP LINK 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

*Ethernet Port Wiring
The PoE switch family supports one RJ-45 uplink (port UP LINK 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 & Port 2 provides Power over Ethernet function that delivers DC power through the data
pairs(4 pairs or 2 pairs) to the PD. UPLINK port provides Power Device 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 maximum90W ability to power up the powered device
use the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE802.3af Alternative A(MDI-X) + B mode connector assignment.
The following table shows pin assignment of alternative A and B for the Power Source Equipment.

Be sure the twisted pair cable is bound with the standard RJ-45 pin. 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.
