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.

Safety Protection

The injector provides safety protection design for operation. The individual power output of each PoE

OUT port is shut down when any of the following events occurs:

Incompliant PD

An incompliant PD is detected on the port.

Disconnection

A PD disconnection.

Overload

An overload situation is detected on the port.

Over-current

An over-current situation is detected on the port.
