1. Introduction
Power over Ethernet provides a way for Ethernet network devices to be powered by UTP cables, including
Cat.5, 5e, and 6 rather than by separate power cords. The device is a mid-span injector that can deliver output
power supporting proprietary PoE++ 90W Type 4 PDs, 802.3at Type 2 high-power PDs, and 802.3af Type 1
PDs. The injector supports both Fast Ethernet connection and Gigabit Ethernet connection.
For no damage to the connected device, it is enhanced with smart design to discover compliant PD. It shuts
down the power immediately when incompliance is discovered. For safety, other protections for conditions
such as disconnection, overload, over-current, and short circuit are also provided to secure your network
installation. It is an ideal mid-span that supplies reliable, uninterrupted power up to 90W to IP phones, 802.11
access points, pan-tilt-zoom cameras, and other Ethernet devices using existing LAN cable infrastructure.
1.1 Features
Supports both Fast Ethernet and Gigabit Ethernet
Backward compatible with 802.3af and 802.3at-compliant PDs
Delivers power output to support 90W PD
Type 1 ~ Type 4 compliant PD discovery & classification
Power shutdown protection for incompliant PD
Power shutdown protection for disconnection
Power shutdown protection for overload, over-current, and short circuit
Multiple built-in power connectors to support a variety of external power supply
Plug and play with no configuration required
Supports DIN-rail and panel mounting

2. Installation
2.1 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire and damage to the product, observe the following
precautions:
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the
part or contact your trained service provider:
-The power cable, extension cable, or plug is damaged.
-An object has fallen into the product.
-The product has been exposed to water.

1. PoE output voltage is about equal to DC IN voltage with a small voltage drop of 0.2V typically.
2. PoE output current maximum can be treated as a threshold of over-current event.
3. PSE output power max. ~= PoE output voltage x output current max.

2.4.1 Power Loss
The power voltage received at the PD end over Cat.5 is different from the voltage supplied at the device’s DC
power connector. The voltage drop is caused by the resistance inside the device and the Cat.5 LAN cable line
resistance before the power arrives PD end. The voltage drop means power loss in the path of power delivery.
Here is some information for reference.

Note:

3. Making LAN Connections
3.1 Data In Jack
The RJ-45 jack is used to connect a PoE-incapable Ethernet device that communicates with the remote
powered device. The injector operates transparently to Ethernet port functions like auto MDI/MDI-X function
and Auto-negotiation function. The network signal is forwarded to PoE OUT jack.
It supports:
Ethernet interfaces
10BASE-T, 100BASE-TX, 1000BASE-T
Network Cables
10BASE-T: 2-pair UTP Cat. 3, 4, 5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
3.2 PoE OUT Jack
The RJ-45 is enabled to deliver power together with network signal to a connected powered device via Ethernet
cable. To make a IEEE standard PoE connection, the connected PoE PD must be IEEE 802.3at or IEEE
802.3af-compliant device for safety reason. For proprietary PoE++ PD classes, only the PDs in certified list are
supported the injector.
Network cable for PD connection
4-pair Cat.5, 5e, 6 or better
No bundled cable for proprietary PoE++ classes
No 2-pair cable
Safety Features
The injector is equipped with the following capabilities for a safe and reliable connection:
1. Detection for an IEEE 802.3af /802.3at/Proprietary PoE++ compliant PD.
2. No power is supplied to a device which is classified incompliant PD.
3. No power is supplied when no connection exists on the port.
4. The power is cut off immediately from powering condition when a disconnection occurs.
5. The power is cut off immediately from powering condition when overload occurs.
6. The power is cut off immediately from powering condition when over-current occurs.
7. The power is cut off immediately from powering condition when short circuit condition occurs.

-20-
3.3 Connection Distance
Connecting standard PD
The following figure illustrates a typical application of the device connecting to a standard PD.
The cable distance including the segment from the injector to the Ethernet device and the segment to PD is no
more than 100 meters.
Connecting PoE splitter
The figure below illustrates another example that the device connects to a PoE splitter for a non-PoE device. A
PoE splitter operates as a PD that splits PoE input to pure power line and separated LAN interface.
