1. General Information
The SFE-SW5G PoE (Power Over Ethernet) Switch family provides four 10M/100M/1000M TX
ports with PoE PSE function plus one 10M/100M/1000M TX up-link port with PoE PD function. It
accepts power from PoE power souring equipment (PSE) and delivers power to PoE powered
device (PD), which are compliant with IEEE802.3af and IEEE802.3at standard 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 200 meters. This manual will help you to
install and maintain the PoE switch. Installation of the PoE switch is very easy and you can start to
use the product as soon as it has powered up.
2. Hardware Description
*LED Indicator
There are 12 LEDs on the PoE switch to indicate the status of power and signal. The following
section describes the functions of each LED indicator.

The PoE switch allows to be powered by another PoE source on port 5 (UPLINK) and/or on rear
terminal,
If powered on port 5 (UPLINK) as a PoE repeater, the PoE input must be 44~57VDC, the input
current is not over 2Amp.
If powered via the rear terminal, please make sure the input current is not over 10A.

For PoE operation, total output is 35W (802.3at) x 2 or 17W (802.3af) x 4. Please note that the full
load output only be achieved using 24VDC (or above) input voltage. If your input is 12VDC, then
the total load should be de-rated.
Ports 1~4 will deliver DC power over the Ethernet cable as detailed below:
Mode A: SFE-SW5G25A4
* 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 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
Port 5 (UPLINK) may receive 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

The terminal block on the rear panel should be wired as detailed below:
The DIN-4P connector on the rear panel also used for power input, you can use an AC/DC adapter
with DIN-4P connector directly, recommends adaptor MS-180-18 or MS-180-24 as detailed below:

*Ethernet Port Wiring
The PoE switch family supports one RJ-45 uplink (port 5 with PoE PD) and four RJ-45 ports (port
1~4 with PoE PSE) with automatic MDI/MDI-X crossover, auto-sense for 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 to 4 provides Power over Ethernet function that delivers DC power through the data pairs C
& D (pin 4,5 and pin 7,8) (mode B) to the PD. Port 5 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. The
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 to 4 provides PoE injection function with maximum 35W ability to power up the powered
device using the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE802.3af Alternative A and/or B mode connector assignment. The
following table shows pin assignment of alternative A and/or 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 NegativeVport
7 Negative Vport
8 Negative Vport
Be sure the twisted pair cable is bound with the standard RJ-45 pin, especially the pins 4, 5, 7 and 8.
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 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.

User’s Manual SFE-SW5G series
*Network Application
The PoE Switch can receive power from a 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 the PoE Switch.
