KTI Networks KPOE-800-2P Making Powered Device Connections, PoE OUT Port Power, Incompliant PD

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.

PoE OUT Port Power
Voltage	48VDC on jack pin 4/5 (V48dc+) and jack pin 7/8 (V48dc-)
Power (per port)	15.4W maximum per port
Power (per unit)	1	Power Model - 60W for all 8 PoE OUT ports
	2	Power Model - 120W for all 8 PoE OUT ports

Connection Distance

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.
