POE Conversion help....
Hi guys, we have a Mikroitk QRT on a mast running from a POE injector down below in the building, it's all working fine. We now need to add an IP camera on the mast which will use the same cable and needs to run from POE as well. The QRT only has one port and we need that radio, an omnitik with poe out won't work, so we need to split the cable somehow with a hardened switch or something, but the catch is that the Mikrotik passive POE won't run the camera as it's 802.3af, I am looking for some quick to implement and relatively cheap ways of making this happen and was hoping somebody would have some simple suggestions ? There is no option to run a second cable so I have to make this work somehow with one cable L Regards Paul
Do you require Gig on either? If not, turn it into two two-pair cables which are only able to do 100mbps? Green and orange on one, Blue and brown on another.. Used to be standard practice if you needed to put two devices on one cable.. You used to be able to be ready-made splitters to go on either end of the cable too, not sure if you still can..

Thanks for the suggestion Damien, I only need 100M and did think about this option but wasn't sure about the pins/cables that the POE used for each type of POE, there seems to be two standards for 802.3af which use different pairs.....

Far from an ideal solution... but you could use two pairs from the cable for data, plug that into something like an RB750 to split to your QRT and camera - and use the other two pairs for your DC power - connecting to the power jacks of the 3 devices up the mast rather than trying to PoE power them. And this is why I always get our electricians to double whatever our immediate requirements are when it comes to data cabling :) -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Paul Julian Sent: Tuesday, 21 October 2014 7:24 PM To: public@talk.mikrotik.com.au Subject: [MT-AU Public] POE Conversion help....

Thanks Thomas, I totally agree and this has to be probably the only site where we didn't install 2 cables from day one, of course..... That option you are suggesting might be the best one and probably the easiest to implement, I might just put a small box on the mast and a krone block to split the power out there or something and put a 750 in there as a switch.

Hi! Have you selected the camera yet? If not, I am sure there are a few camera models available on the market that have poe-passthrough, in which case you can just choose one that either: Supports passive PoE, then hook it up using the same cable and injector that is in place, or Supports 802.3af, then power the cam with 48v power supply (or Poe Switch) and use 802.3af converter for the QRT Cheers! Mike.

Thanks for the suggestions Mike, unfortunately I already have the camera and need to make it work somehow. Good news is after many hours I have found a combination that works, amazingly..... To get it working this is what I have had to do, it's messy but it works.
From a 802.3af POE switch I run one cable from a POE port to port 1 of an Ethernet splitter (2>1) then run another cable from a normal Ethernet port on the switch to port 2 of the splitter. On the other side of the splitter where there is just the single cable I plug that into a Mikrotik Gigabit POE injector, I also plug 24V power into that injector. I then run the single cable as long as I needed to, so far only in the office but the run isn't very long at the site. At the other end of the cable I place another Ethernet splitter (1>2), however before I go into the splitter I placed another Gigabit POE injector but around the wrong way, so POE+Data side facing the other injector at the head end, then in port 1 of that splitter I run a cable straight to the 802.3af POE camera and it powers up by using the POE from the switch over the data pairs, I had to use the right port on the splitter, only the one which transported the original 1,2,3,6 cables worked, this was port 1 in my case. Then port 2 runs to another Gigabit POE injector with the POE+Data heading away from the splitter to the Mikrotik QRT. From the second POE injector, just before the second splitter, I take power from that and then feed it into the 3rd POE injector which ultimately goes to the QRT.
I know this is a long way around to get the result but I simply had to work with what I had and what I could get to work. Anyway, it works and will save my butt tomorrow :-) I hope it helps somebody else anyway.
