The house I bought has a patch panel in the middle of the house. All good, except the house is 2 story and has a concrete floor.

So changes to the networking is not possible... bugger.

This includes a cable that went to the ETP for the old phone line.

So my question is, if they terminate the existing cable with a UTP plug, can I then use a POE injector to power up the ONT ?

I would preferably like the ONT to be external to the house as there is no easy way to have it powered internally anyway.

is having an external ONT available in NZ ?

is powering it via POE possible ?

TIA for any info

Keith

ONT must be internal and must be located next to a power socket. It's not possible to POE power it.

You could use something like this, but would probably void chorus's t&c

There are lots of ways of hacking and soldering power cables to deliver a passive POE solution.. BUT since Chorus won't install an ONT unless it's right next to power it's pretty much a moot discussion.

I suspect @chorusnz would have something to say about installers who put an ONT either A) Outdoors or B) Somewhere where there isn't any power. Since part of completing the job is to have it actually working.

Hahaha.... the amount of times you see an ONT in the middle of nowhere with a power extension cord running to it. Funnily enough the locations tend to line up with the ETP.

Exactly what was first proposed for our place, along with removing a cupboard from the garage.

Pleasingly, we eventually came up with a much better solution.

Having an ONT connected via an extension cord is a different issue, however I completely agree that *shouldn't* happen. But I have seen it a number of times.

I would hope these days it happens less often... but I am probably wrong here.

This includes a cable that went to the ETP for the old phone line.

I am assuming the Patch panel has power , so the issue is to get the fibre to the panel,

Microduct is pretty hardy, and it could be possible to use the existing phone line cable as a draw wire, to either draw through the microduct, or to draw though a steel string you could then pull the microduct through on,

You might need a few holes in the Gib in places where it gets a bit tricky, but in the end that is nothing that cannot be plastered over and in the end you end up with an ONT in the place it should be....

Thanks for the link - that is interesting for a number of things potentially.

The patch panel is located in the mille of the house, down stairs. There is power there.

I will go roof crawling tonight and see how the CAT5 is run in the roof space over the shed. It may be a better idea to cut a hole in the shed wall close to where the ETP for the phone line is, terminate the cable and have an outlet in the shed, this could feed through to the patch panel using existing cabling. I could then connect the ONT to power in the shed and glowing lights will keep the dog company at night.

But just to make my life even better, I am up a private road so I need to get "permission" from the other 17 home owners before they will start. A lot of them are retired people and understand sod all about the internet.

sigh, it may be easier to move....

No, no, no, no, no.

Just get Chorus to put the ONT in the Patch Panel. It's the right place to go as that is the location where the router will go and has power. Yes it may be ugly getting the fibre there but don't even consider putting it anywhere else. It's madness.

I wired up some security cameras once with "hacked Poe" they were DC 12v cameras. Cat5e has 4 twisted pairs, total of 8 conductors. I used two pairs (4 conductors) for data as that's all you need for a 100mbit patch cable, and crimped an RJ45 plug strait onto only those making sure the pinning was correct. The other two pairs carried the DC and I soldered DC connectors onto these. It worked without any problem, although Poe is usually run at a higher voltage 24 or 48v to overcome resistance in the longer runs of cat5e. The voltage will drop in longer runs due to ohms law, the voltage drop will depend on the amount of current draw by the device. There will be regulators inside the device to drop the Poe voltage down to the required operating voltage, usually 12v and 5 or 3.2v for logic level.
