Important Information
What you should know about Power Over Ethernet (PoE)
Power-over-Ethernet (PoE) or "Active Ethernet" eliminates the need to run 240 Volt power to
Wireless Access Points and other devices on a wired LAN. Using Power-over-Ethernet systems,
installers need to run only a single CAT5 Ethernet cable that carries both power and data to each
device. This allows greater flexibility in the locating of AP's and network devices and significantly
decreasing installation costs in many cases. The placement of a Network device can be up to 328
feet (100 meters) away by using standard category 5 Ethernet cable.
Power-over-Ethernet begins with a CAT5 "Injector" that inserts a DC Voltage onto the CAT5 cable.
The Injector is typically installed in the "wiring closet" near the Ethernet switch or hub.
Some Wireless Access Points and other network accept the injected DC power directly from the
CAT5 cable through their RJ45 jack. These devices are considered to be "PoE-Compatible" or
"Active Ethernet Compatible".
Devices that are not "PoE Compatible" can be converted to Power-over-Ethernet by way of a DC
"Picker" or "Tap". These are sometimes called Active Ethernet "Splitters". This device picks-off the
DC Voltage that has been injected into the CAT5 cable by the Injector and makes it available to the
equipment through the regular DC power jack.
WARNING: Never connect the Injector - Power Over Ethernet Out directly to a network
device such as a Hub, Switch, IP Camera or Print Server unless you are
ABSOLUTELY sure the device and network is PoE Compatible. Additionally,
make sure your PoE compatible device or network is designed to handle
the 48 volts DC delivered by the PoE injector. If you do not check the POE
compatibility and voltage required, you will damage the attached device, the
Injector and any computer connected to the network. NetComm will not
