1. General Information
The PoE Switch PSE-SW8G44D0++ provides seven 10M/100M/1000M TX ports with PoE PSE
function plus one 10M/100M/1000M TX up-link port. It allows power souring equipment (PSE) to
be powered from DC source and delivers power to any PoE powered device (PD) which is
compliant with IEEE802.3af/at standards.
In the LT PoE++ model, the PoE PSE delivers power up to 70W/port to a PD. The LTPoE++ is
Linear Technology Corporation’s specification. This specification provides detection and
classification extensions to existing IEEE PoE protocols. It is backward compatible with IEEE
802.3af and 802.3at.
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
The PoE switch PSE-SW8G44D0++ use LT PoE++ chipset, for PoE operation, make sure your
power supply may offer at least 125W for 7x 802.3af PoE ports, or 250W for 7x 802.3at PoE ports,
or 650W for 7x LTPoE++ ports. The input voltage must be in the range of 44 to 57VDC if using for
802.3af operation. The input voltage must be in the range of 50 to 57VDC if using for 802.3at
operation. The input voltage must be in the range of 55 to 57VDC if using for LTPoE++ 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.
(option: you may use 2x MS-180-56 (56VDC/3.21A) or 2x MS-270-56 (56V/4.82A) as the DC source)
Ports 1~7 will deliver DC power over the Ethernet cable as detailed below:
* 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 terminal block on the rear panel should be wired as detailed below:

*Ethernet Port Wiring
The PoE switch supports one RJ-45 uplink (port 8) and seven RJ-45 ports (port 1~7 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 7 provides Power over Ethernet function that delivers DC power through the data pairs
(mode A, mode B & 8 pairs) to the PD.
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 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 7 provides PoE injection function with a maximum 70W 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/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)
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 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.
