INSTALLING THE 828P POE EXTENDER KIT
The Enable-IT 828P – A Dual Output PoE and Gigabit Extended Ethernet Unit has a distance restriction of 800ft or 240m over 4-pair Category 5e or higher spec rated wiring. Multiple 828 units can be daisy chained to reach up to 2,000ft or 1,828m. For the 828P daisy chain use additional 828W units.
We highly recommend that you perform a quick test to ensure the working order of your Enable-IT 828P PoE Ethernet Extender units prior to installing.
This will also serve to familiarize you with how easy the process should be. Using a Ethernet patch cord attach the 360 PoE Injector (Power & Data Out jack) to the 828P left side (single port) sealed jack as shown below in the diagram.
Next use another Ethernet patch cord to connect one of the 828P right side (dual ports) jack to your PoE device. Using the power cord, power up the 360 Injector. The left side Green Power LEDs will turn on and all Yellow Link LEDs will flicker for LAN traffic activity. This confirms basic proper operation of the units.
For a more detailed test and to confirm your LAN Equipment works with the 828P units, connect your Ethernet LAN to the PoE injector LAN in port and then test LAN port and test connectivity all the way end to end.
You will need a long flathead screwdriver to carefully remove the Ethernet patch cables from the deeply recessed ports prior to installing.
LED indicators will provide visual operational status of the 828P 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 828P PoE Extender and your end device is incorrect, the wiring may have a short or the distance from the 828P PoE Extender unit through the your remote LAN device exceeds 800ft or 240m.
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 828P PoE Extender LINE ports. The RJ-45 Pins are straight through just like an Ethernet patch cord.
DO NOT INSERT THE BLANK RJ-45 HEADS PROVIDED INTO ANY PORTS BEFORE CRIMPING
– OTHERWISE YOU WILL RENDER THE PORT USELESS – BENT PINS
Will the 828P 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 determine the amount 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, then 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? – 200ft? 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 400ft? use a 48V PoE.
