White adapter plug
 

Hi guys.

I am doing a self install on virgin tomorrow. I have located the white box where the cable that goes into the hub is but there is also another cable coming out the box that has a plug on the end of it? Never seen this before any clue what it's for?

Thanks.

James

Can you post a photo?

ps. Welcome to the forum!

It won't let me. It looks like a white 5 volt charger plug but the cable comes straight out the white box. Says virgin media on it.

Re: White adapter plug
 

Was it left by a previous occupier? I suspect it's the cable they used to connect to their modem and you can replace it with the new one you've been sent.

But I'd still like to see the "plug". Can you post a photo somewhere else, and a link on here maybe?

Sounds like it could be a HDU power supply...

Re: White adapter plug
 

I have been told that it is a power supply so there is no need for a green box on the street but the plug needs to always be in for the router to work. I will try to link a pic

If you're in a FTTP area I could be the power supply for the unit outside (forget what is called) but its most likely a HDU which is a splitter that has no loss, but needs power

Re: White adapter plug
 

It is definitely a power supply for the unit outside just never needed one in my last house so seemed strange that it needed power

Re: White adapter plug
 

Not something like this is it?

Re: White adapter plug
 

No it literally looks like a mobile phone charger connected to the white box

Re: White adapter plug
 

I think it's called an ONT (Optical Network Terminal)

Yup, that's an ONT power supply.

You can tell that's what it is as it's connected to coax.

An HDU has a normal power connector.

So you'll need to leave it connected and plugged in.

Re: White adapter plug
 

Why is it needed as never used it before? Not an issue just wondering

I think I replied to this on the thread you created on the Community Forum

Normally there is a big Fibre to coax converter somewhere on a road that connects to multiple addresses. You can tell what they are as they're much bigger and make a noise as they have fans and other power to them.

From that point it's then coax to your home.

With the newer FTTP area installs, the fibre is installed all the way to an address, and then each home has a converter. But these then need their own power supply.
