Forest, How far away are we from being able to order the new larger units with just Cambium power and sync? Got a few projects coming up soon and I would love to put one unit instead or two or three.

In progress.... :) I was going to hold off announcing this until we were sure it was going to work, since the 'mechanical issues' we're working through are a side effect of this, and I'm confident but not 100% sure we're close to solving them. But since it was brought up I'll give a bit of a look behind the curtain so to speak: At some point the light went on in my head that I could add a set of jumpers to each port just like on the Gigabit PoE injectors and make the syncinjectors radio-universal. I struggled with how to make the jumpers accessible until I realized that I could just get some more holes cut in the bottom of the syncinjector case. For the existing 4 port injectors, this isn't a problem as those holes can be added to the side of the case closest the circuit board and we can put the jumpers on the side of the circuit board closest to the holes and everything would work fine. Unfortunately, the syncinjector currently in work is the 12 port injector. This adds an additional hurdle that there are two boards, each with 12 ports. Each board needs to be close to a side to make this work, which means the orientation of the boards are flipped in relation to each other (laying the unit on it's side, one is 'right side up' with the connectors sitting on the circuit board, and the other board is upside down with the connectors hanging from it (just like in the existing product)), effectively placing the two boards themselves as far apart as possible in the enclosure. This isn't a problem except that the enclosure is two U shaped pieces of plastic which the boards snap into one U and then the second U snaps on the resulting assembly as a cover. With two boards, one ends up very near the bottom of the U which requires a fair bit of flexibility to be able to snap the board into without breaking the enclosure. The other board ends up very near the top of the U which requires a fair bit of ridigidity to hold the board in place given the distance the sides are from the U. We think that the current material we're planning on having the enclosures use will be both flexible and rigid enough - but its' been a bit of a challenge ensuring that. I'm supposed to be getting first samples soon and if that works, we'll be shipping the 12 port injectors with 4 jumpers per port to set the pinning. If this iteration doesn't work, we'll just go to production with the 12 port injectors without the jumpers and a mechanically less-troublesome orientation and then re-spin the 4 port injector fairly soon to add them to that product, and then re-visit the 12 port injector jumpers at some future date, possibly after the rackmount stuff (hopefully) finally comes out. On the other hand, in the meantime, there isn't any reason why you shouldn't be able to swap the blue and brown pairs in the cable going both into and out of the current syncinjectors to get the non-canopy radios to work with gigabit on the syncinjector. -forrest On Apr 16, 2015 6:03 PM, "Mathew Howard" <[email protected]> wrote: So what we need is a Syncinjector with jumpers like on the Gigabit PoE injectors...

Airmax stuff is all 4/5 positive and 7/8 negative, I imagine the 10/100 stuff would work fine with the power pairs swapped, but I don't know what that would do to gigabit. I don't think it's going to work with AF5x, since they use power on all four pairs. On Thu, Apr 16, 2015 at 6:19 PM, Josh Luthman <[email protected]> wrote: I didn't check...sorry.

Probably applies to the ePMP Sync radio too. So, with that in mind.. does the UBNT GigE PoE stuff use all 4 pairs for power? If it's 4, 5, 7 & 8, it may be possible, but... you'd have to flip the blues and browns at one end. I don't know what that would do for the GigE data interface though. It might not work. You can use a 568B to 568A (aka standard cross-over) cable and GigE still works fine, but I'm not sure about crossed blues and browns. Someone smarter than me would probably have to give you a thumbs up or down. On 4/16/2015 4:55 PM, Josh Luthman wrote: Has anyone tried these syncinjectors for Ubnt Airmax radios? What about anything else? I'd love to use this one product for all sites from now on. Is it possible to run the AF5x?
