I want to provide LAN and power to switches through a single CAT-6 UTP cable

post #1 of 8
Thread Starter 
IIn my Village i am providing internet services . I want to provide LAN and power to switches through a single CAT-6 UTP cable. I know that wires 1, 2, 3 & 6 of CAT-6 UTP are used for data transfer & receive. Wires 4, 5, 7 & 8 are not needed.
Now, if I connect wires 1, 2, 3 & 6 in RJ-45 for LAN and wires 4, 5 or wires 7, 8 for power, will that work?
Please note, wires 4, 5, 7, 8 would be unavailable in RJ-45 connector.and there are 7 switches in a row.

mhm you want to power a switch with poe ?
Where is the power comming from ?
You might power a small switch via ethernet poe but this switch won't provide poe for sure.

anyways I don't think you can do what you want.

I'd suggest broadening your knowledge to a large degree if you want to be your own makeshift ISP.

Most PoE implementations provide -48v DC up to a max of around 15 watts.
This is good for things like a wireless access point, IP camera or VoIP phone, but would be insufficient for a switch.

If you're suggesting wiring up 120v AC or main power through a UTP cable in tandem with data, please don't try.

I'm looking to do the same thing with a couple of non POE IP cameras that only run at 10/100. 10/100 only uses 2 pairs I was going to use the other to pair to power the cameras with a separate connector. I'll let you know if it works.

The only way you can give a device power is if it is PoE. That means the end device needs to support (receive PoE from the switch) and the starting device i.e. switch sends power. If you do not have one of these it will not work. What will most likely happen even if you were able to make shift something; would not be able to pass traffic due to the EMI you have just self generated. That is if you don't blow devices on either side up, or electrocute yourselves.

This is a forum you come to, to get help on things that are feasible not impossible nor a forum to ask how to kill yourself or put others in harms way because your too God dam cheap to get the equipment needed to do the things you want.

As beers stated PoE will not provide power to a switch or multiple switches. A switch that supports PoE means that it will provide power for certain devices (IP Camera's, VoIP Phones, "certain Access Points, thin clients are about the only things that I can think of that will support PoE)!

EMI may deteriorate the signal but it may not I have to see I don't think any one could say either way with out trying. And as far as it being feasible it is highly feasible. All I'm looking to do is use the 2 extra pairs to carry the 12V DC to a second power connector. Outside the RJ45 connector

Oh and the GS108T is a switch which can receive it's power via POE but not power any POE devices so there are POE powered switches.

I have not got around to trying this yet but found this review today saying he did and it works fine.

4.0 out of 5 stars 5 stars on everything but user friendliness May 25, 2011
By Eric Ripley
Amazon Verified PurchaseFirst off. I purchased one of these cameras to make sure it meet my needs before getting another and then finally 4 more. I have a total of 6 cameras protecting my property and am using the blueiris software to record and manage the cameras. It is the best software but this review is not for the software ,which is excellent, but for the camera.

Camera construction:
Robust. Perfect for outdoors. In fact all my cameras are outdoors but under overhanging eves. The shell is waterproof and cord out of the camera is waterproof as well.

Wiring the cameras:
These are wireless cameras but i will inform you that you will have to run a wire of some sort as these cameras will need wired power. so i went ahead and wired the cameras via ethernet as well since i had to run power. one suggestion is you can use what i did and run cat6 for the ethernet and POWER. that is if you are technically inclined. I used 4 wires for the ethernet (orange, orange white, green, green white) and the blue and blue white for power and the brown and brown white for ground. I physically cut the power cord that comes with the cameras in half and soldered one end to the ethernet cable extra wires and the other end. the cameras are really low wattage so you can easily get away with this. I ran 40 feet of cable this way and the cameras work fine.
