Netonix Forums

Hi

We're moving a lot of our sites to straight DC.
On a couple of sites we are still using Ceragon IP10's.
These have an IDU that we are currently powered up with a Meanwell power adapter which runs off AC mains power.
The IDU takes -48V.

Is it safe to power the IDU with CAT5 from the Netonix?
I've made a test cable by tying off the 4 pairs (pos: 1,2,4,5 neg:3,6,7,8) and it's reading the expected 48V.
Just want to make sure I'm not missing anything obvious by doing this - anything to watch out for?

thanks

It's hard for me to say if this is ok. Out POE ground is bonded to our negative power input on our DC switches. So a lot of it depends on if anywhere in
your system, the + battery power gets tied to the chassis ground anywhere. If it does you can't use our present family of DC switches.

Hmm, ok.
I can just run it off our DC supply anyway, would have just made my life easier if I could power it off the Netonix!
Is there an adapter you can get that will make this possible?

don't have an adapter I can recommend.

We are however, coming out with a series of isolated supplies in the future, meant for telecom -48 volt sites.
