TP-SW8
1. General Information
The TP-SW8 POE Switch family provides a PoE/Data input port that is compatible with 802.3af
and 802.3at (Type 1 and Type 2) and it has seven 10M/100M TX ports with PoE PSE function. In
addition to the ability to accept standard 48VDC power on the Ethernet input Port 8, the
TP-SW8(-NC) provides 2 secondary DC wire terminal input ports for PoE switch operation from
12VDC to 58VDC. PoE output voltage is equal to the input voltage, making this switch as universal
voltage PoE switch. The PoE Switch can be used as an Ethernet/PoE repeater to 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. The TP-SW8 comes with DIN rail mounting clips for ease of mounting in network cabinets.
2. Hardware Description
*LED Indicator
There are 18 LEDs on the PoE switch to indicate the power and operational status. The following
section describes the functions of each LED indicator.

*Power wiring
The PoE switch accepts input voltage from terminal block (rear panel) or RJ45 cable (port 8). If
power input from terminal block, the input voltage must be in the range of 12 to 57 VDC. Input
current on secondary wire terminal input is 10A max. Input current on port 8 is 2A max.
If power input from the RJ45 cable (port8) in the TP-SW8, the input voltage must be in the range of
44 to 57VDC if running for 802.3af operation or 50 to 57VDC if running for 802.3at operation.
If the TP-SW8 is not powered within IEEE802.3af/at specification, it will only function as an
ethernet switch without PoE output.
The PoE PSE ports will deliver DC power over the spare pairs as the connection:
* TX on lines 1 and 2
* RX on lines 3 and 6
* V+ on line 4 and 5
* V- on line 7 and 8
The Port 8 may get power over the signal pair or spare pairs, the connection as:
* Data pair A plus V+ /V- on lines 1 and 2
* Data pair B plus V-/V+ on lines 3 and 6
* V+/V- on line 4 and 5
* V-/V+ on line 7 and 8

*Ethernet Port/PD Port Wiring
The PoE Switch supports Port 1 to Port 8 with automatic MDI/MDI-X crossover, autosense of the
speed and duplex for 10Base-T or 100Base-TX connections. 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 port 7 also provides PSE function which delivers DC power through the spare pairs (pair
4,5 and pair7,8) to the PD. Port 8 provides PD function that receive power from 4 pairs or 2 pairs
Ethernet cable.

The following tables depict 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 green or yellow Link/Act 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 it is connected to.
The maximum cable length for 10/100BaseT with Cat 5 twisted pair cables is typically 100 meters
(328 ft.).
3. Network Application
The PoE Switch can receive power from PoE midspan and provide power to the PD. It will power
802.3af compliant devices if it is powered at 48VDC although it will not perform the 802.3af
handshake with the client device. The PoE Switch can be installed in a more appropriate position
