Enable-IT 828WP Outdoor PoE Extender FAQ Wiring Diagram
nable-IT 828WP Outdoor PoE ExtenderThe 828W includes an Enable-IT 360 PoE+ (56V) injector and is a self-contained solution ready to go. The 828W drives incremental Gigabit Ethernet and your PoE to 800ft (240m). This cost effective unit blows away any previous solution, including fiber, for very quick plug-and-go installation of PoE IP cameras, PoE Access Points and remote LAN segments.

The 828W PoE Extender unit works fine in the lab for the out of the box test, but when I placed them in the field all I get on the 828W PoE Extender unit is a Green CO Power and Amber CO LAN Activity light.

The issue clearly is the wiring between the 828W PoE Extender unit. Check your cabling and connections and if you may have bent any pins in the RJ-45 connections on either 828W PoE Extender unit.

We highly recommend a quick test to ensure the working order of you 828W PoE Extender unit.

To do this, please use one of the Ethernet patch cords provided and attach each end to the LINE port on the 828W PoE Extender units. Next use another Ethernet patch cord to attach a

LAN device to the Data/PoE – OUT port of the 828W PoE Extender Unit.
Next step is to attach another Ethernet patch cord to the Data/PoE – IN port of the 828W PoE Extender unit. Final step is to apply Power to the 828W PoE Extender unit unit.

LED indicators will provide visual operational status of the 828W PoE Extender units.

CPE Sync / Act – Indicates remote LAN is visible and connected with activity.

If this LED fails to light, the wiring between the 828W PoE Extender and your end device is incorrect, the wiring may have a short or the distance from the 828W PoE Extender unit through the your remote LAN device exceeds 900ft or 274m.

LAN Act – Indicates local LAN is visible and connected with activity.

Power – should be lit when 5v adapter is connected and powered

This confirms proper operation of the units.

For installation at your desired location, keep in mind the following:

The backbone cable between the CO – RJ-45 LINE ports uses –

2-pairs of wiring for data and voice use only (RJ-45 pins 1,2,3 & 6) or 4-pairs of wiring for data, voice and PoE (All RJ-45 pins)

Two RJ-45 blank male heads have been provided in the kit for use in connecting your wiring to the 828W PoE Extender LINE ports. The RJ-45 Pins are straight through just like an

Ethernet patch cord.



Will the 828W PoE Extender work with any manufacturer’s wireless AP?

Yes, if using a IEEE 802.3af standard PoE injector or PoE midspan switch. Cisco PoE switches do not work as they do not startup in a 802.3af mode by default and can’t configure itself for Long Reach Ethernet.

We recommend using a standalone PoE Injector when in doubt.

IEEE 802.3af standard passes power over Ethernet on pins 4,5,7 & 8. Using a straight through CAT5e cable for PoE – Pins 1,2,3, and 6 carry the data while pins 4,5,7, and 8 carry power
PoE injectors can come in(24,48 and 56V) variations. PoE equipment on the other hand can be any voltage up to 56V. Each PoE Equipment mfg has a built in regulator that takes whatever voltage coming out of a PoE/Data cable and conditions it down to what it needs.

Voltage drops over distance using wires. At 200M, you lose maybe 4 or 6 volts. At 48VDC, that leaves you with 42 volts. You can decide the measure of voltage drop over a distance by finding the resistance of the cable for a specific temperature (given in ohms/1000ft) from the cable manufacturer or electrical wholesaler. If you know the largest amount of current that will flow in the cable, when use the formula: Vdrop = Current X Distance (Ft) X 2 X Ohms per 1000Ft.

As a rule of thumb you will loose 6V per every 100? – 200? of wiring, depending on the gauge. Lower power also means more amperage means more heat and perhaps issues with the 24 gauge wires in CAT5. You may need to use 18 gauge wiring. For all intensive purposes anything greater than 400? use a 48V POE.
