1. General Information
The PoE PSE-SW8G (Power Over Ethernet) Switch family provides seven 1 M/1 M/1 M TX
ports with PoE PSE function plus one 1 M/1 M/1 M TX up-link port with PoE PD function. It
allows power souring equipment (PSE) to be powered from PoE and delivers power to any PoE
powered device (PD), which is compliant with IEEE8 2.3af and IEEE8 2.3at standards to receive
and deliver both Ethernet data and DC power through the traditional UTP or STP cable. The PoE
Switch can extend Ethernet data and DC power up to 2 meters.
2. Hardware Description
*LED Indicator
There are 18 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
48VDC typical (44 to 57VDC) (P/N: PSE-SW8G44A4/PSE-SW8G44B4/PSE-SW8G44D4)
The PoE switch family can be powered by another PoE source on port 8 (UPLINK) as a PoE
repeater or extender.
For PSE-SW8G44xx, the range is 44~57VDC,
For PoE operation, make sure your power supply may offer at least 125W for 7x 8 2.3af PoE ports,
or 25 W for 7x 8 2.3at PoE ports. The input voltage must be in the range of 44 to 57VDC if using
for 8 2.3af operation. The input voltage must be in the range of 5 to 57VDC if using for 8 2.3at
operation. If the PoE switch is not powered with the above designated input voltage, it will only
function as an Ethernet switch without PoE output.
In the full range voltage model, if powered via the rear terminal, please make sure the input current
is not over 15A. If powered on port 8, make sure the input current is not over 2Amps. (over 1A,
the gigabit signal will de-rate to 1 M)
Ports 1~7 will deliver DC power over the Ethernet cable as detailed below:
In the A mode: * Data pair A plus V+ on line 1 and 2
* Data pair B plus V- on line 3 and 6
* Data pair C on line 4 and 5
* Data pair D on line 7 and 8
In the B mode: * 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
Port 8 may get DC power over the Ethernet cable, as detailed below:
* 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 8 with PoE PD, and seven RJ-45 ports (port
1~7 with PoE PSE) with automatic MDI/MDI-X crossover, auto-sense for speed and duplex for
1 Base-T, 1 Base-TX or 1 Base-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 to 7 provides Power over Ethernet function that delivers DC power through the data pairs
(mode A, mode B & 8 pairs) to the PD. Port 8 provides Power Device function which receives
power from 4 pairs or 2 pairs Ethernet cable.
The following tables describe the wiring diagram of straight-through and crossover cabling. The
crossover cables simply cross-connect the transmission 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 ED 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 1 /1 /1 BaseT with Cat 5 twisted pair cables is typically 1 m
(328 ft.).

*PD Port Wiring
Port 1 to 7 provides PoE injection function with a maximum 35W ability to power up the powered
device using the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE8 2.3af Alternative A/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

1 Negative Vport Positive Vport
2 Negative Vport Positive Vport
3 Positive Vport Negative port
4 Positive Vport
5 Positive Vport
6 Positive Vport NegativeVport
7 Negative Vport
8 Negative Vport
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, the PoE switch will not recognize the PD and won’t deliver DC power to the PD.
The yellow PoE LED will light up when the cable is correctly connected. Refer to the ED
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.

*Networ Application
The PoE Switch can receive power from a PoE midspan and provide power to the PD which
follows the IEEE 8 2.3af/at standard in the network. The PoE Switch can be installed in a more
appropriate position for better performance to extend Ethernet to 2 meters. The following figure
is an example of a network application for the PoE Switch.
