1. Introduction
The Power over Ethernet (PoE) injector is a mid-span power injector designed and tested for use with
all IEEE802.3af compatible PoE Powered Devices (PDs). The PoE injector sits between a switch port
and the PoE powered device, providing inline power capability to an un-powered switch port.
The injector provides modular power design. For high power applications, the injector can be installed
with 2 power modules to support full PoE power up to 120W for eight powered devices. For low
power applications, the injector can work with only one power module and support PoE power up to
60W for eight connections. This flexible modular power design provides cost-effective solutions for
different requirements.
The PoE injector offers the following significant benefits:
ꢀ
ꢀ
ꢀ
Low purchase cost - Installing an injector costs less than upgrading to new PoE switches, since
PoE injectors can easily connect with existing Ethernet switches.
Low installation cost - The injector is a plug & play product making the installation much easier
than a PoE switch. There is no need any software configuration.
Protecting existing and future investment – The PoE injectors are interoperable with all Ethernet
switches and most terminals. PoE injectors can be used in conjunction with different switch
vendors, and end-terminals, which comply with the PoE 802.3af standard. It protects your existing
network installation and future investment as well.

3. Mount two device units as one in a 19” rack.
2.4 Installing Power Module
If you purchased 2 Power Model, you may skip this section. 1 Power Model can deliver total up to
60W for consuming by all eight ports. Calculate the total power budget required for your PD
connections before making any connections.
Most of common PoE powered devices such as wireless Access Points, VoIP phones, IP cameras and
media converters consume power less than 5Watts. However, refer to the product technical
information of individual PD you are using for the power consumption.
If total PoE power more than 60W is required, install one extra power module to the 1 Power injector.
The steps are:
1. Unplug the AC power cord before any installation.
2. Open the cover of the empty module slot.

3. Making LAN Connections
3.1 Making Switch Port Connections
The mid-span injector is designed to support the following PoE incapable switch port types and the
PoE function is transparent and independent to the following port configuration:
IEEE 802.3 std.
10BASE-T
100BASE-TX
1000BASE-T
Port Configuration
Auto-negotiation:
Enable or disable
Transmission speed: 10Mbps, 100Mbps, 1000Mbps
Duplex:
Half duplex, full duplex
MDI or MDI-X
Jack Pins:
Network Cables
10BASE-T:
2-pair UTP Cat. 3, 4, 5, EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair / 4-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5, Cat.5e, Cat.6, EIA/TIA-568B 100-ohm
To make a switch port connection, the steps are:
1. Find an appropriate network cable for a port connection.
2. Connect one end of the cable to the PoE-incapable switch port.
3. Connect the other end to one available DATA IN jack of the PoE injector.

3.2 Making Powered Device Connections
The mid-span injector supports connection to IEEE 802.3af compliant PoE PD (Powered Device). The
Ethernet port of the PD can be Ethernet, Fast Ethernet or Gigabit Ethernet. The injector’s PoE OUT
port delivers power together with network signal to a connected powered device via Cat.5 cable or
better.
To make a connection, the following check points should be noted:
1. For safety reason, the connected PD must be a IEEE 802.3af-compliant device. Un-compliant
devices are not supported.
2. The Cat.5 cables used for the connections must be 4-pair cables. The power is sent over the pairs
(4,5) (7,8) of the cable.
3. Hot-plug connection is allowed anytime.

4. Applications
4.1 Application with Low Power Requirements
1 Power model may be used if the total power budget of the connected PDs is less than 60Watts. One
empty slot can be upgraded with one more power if total power budget increased and is more than
60W in future.
4.2 Application with High Power Requirements
2 Power model can support the total power budget up to 120Watts for all connected PDs.
