Using An Optional Power-Over-Ethernet Injector

The Power-Over-Ethernet Injector can be located at any point between the access point and the LAN access 
port, wherever a convenient power outlet exists. If you supply your own Ethernet cable for connecting power, 
be sure that it is standard category 5 straight-through (8-wire) cable that has not been altered in any way. Use of 
nonstandard cable could damage the access point.
Refer to the illustration below, and follow these steps:

1

Connect one end of the Ethernet cable to the Ethernet port on the access point.

2

Connect the other end of the Ethernet cable to the port labeled 

To Access Point

 on the power 

supply.

3

Connect the power cord to the power supply and plug the cord into a power outlet.

4

To link the access point to your Ethernet network, plug one end of another Ethernet cable into 
the port labeled To

 Hub/Switch

 on the power supply, and plug the other end into a LAN port 

(on a hub or in a wall).

CAUTION:

 To avoid damaging network equipment, make sure that the cables are connected 

from access point to power supply to LAN as shown and described above.
