Re: [AFMUG] Cat5/6 POE splicing while live?
I did one the other day on an old style POE. I managed to cut the wires without blowing it up, but the crimp did it in. bp part15sbs{at}gmail{dot}com On 2/19/2015 11:11 AM, Mathew Howard wrote: I'm pretty sure I've seen plastic crimpers, but I don't know that I'd trust them to do a decent crimp...

The risk is dropping 24VDC across the Ethernet… The power supply might be able to take it but the NIC chip might not.

Re: [AFMUG] Cat5/6 POE splicing while live?
It's not worth the risk of damaging equipment IMO. If this is a common concern, why not have the cable run stop at an outdoor box before going in to the home?

Re: [AFMUG] Cat5/6 POE splicing while live?
We've had installers fry power supplies crimping them while plugged in. If you had a punch down lightning arrestor, it could work. But I'd strip the wire and cut each cable individually.

Re: [AFMUG] Cat5/6 POE splicing while live?
If you are careful when you open the jacket and only cut the blue, then brown pair and don't short them it can be done. Problem is when you re-crimp you short the PoE to the Ethernet and there is no way to avoid that unless you are punching it down or using the crimp caps.

I'm pretty sure I've seen plastic crimpers, but I don't know that I'd trust them to do a decent crimp...

Re: [AFMUG] Cat5/6 POE splicing while live?
If it is a splice you can do as mentioned here and strip back and cut each wire separately and then use those gel splice connectors that I sent you a link to. It's completely safe and won't short like crimping a RJ45.
