KTI Networks KPOE-800-2P Manual De Usuario

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. 

 

Voltage 

48VDC on jack pin 4/5 (V

48dc

+) and jack pin 7/8 (V

48dc

-) 

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 

 

 

 

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.
