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., 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.
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-SW3B25D0H 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. Please make sure the input current is not over 10A.
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
The terminal block on rear panel should be wiring as:
*Ethernet Port Wiring
The PoE switch supports one RJ-45 uplink (port UP LINK) 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.
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 90W 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/bt standard in the network. The following figure is an example of a network
application for PoE Switch.
