Oh right, I didn’t want separate timing cables, that’s what it was. A 12 port Gigabit SyncInjector would be awesome though!

They only do timing, not ethernet. You run dedicated timing cables from the AP to the SyncBox, and then Cat5 from the AP to the Netonix switch for power+data.

We are looking at using SyncBox 12's at the top just for timing FSK (and 450 too I guess). This allows us to run 48V up the tower which we use to power WS-12-250-DC's. The FSK/450 gets timing port sync from the SyncBox and 24V power from the WS-12-250-DC. No need for separate SyncInjectors or DC-DC converters in this scenario. Just an idea.

I understand the same point of failure is in the WS but it's integrated and hidden so I pretend it's not there. :) With the 12awg SOOW we use even on a 600' run there is less than 3% voltage drop. The WS can take as little as 9VDC. The rectifier can easily be tuned up to 27v to offset any drop. Also we gut the AC DC supplies in the 1016 Mikrotik and run it direct DC since it takes 24vdc. Everything is fully DC, finally! I'll reply with ICT price when I'm back in the office. Thanks, 'S Sent mobile!

I realize the WS-12-250-DC's will automatically up-convert to whatever, but they are more efficient if you feed them a higher voltage (~48V). If you already have 4 batteries at the base, what is keeping you from using a 48VDC rectifier? Would you mind sharing the approximate cost of that ICT? Off-list is fine if you would like.

The base of the tower is quite simple: Kendall Howard 12U 19" Wall Mount Rack http://goo.gl/pbpnbk ICT1200-24SBC 24v rectifier (also a 600W version available) http://goo.gl/GkOBBW 12v 45ah TR45-12 Tempest AGM Batteries (4x in parallel and series to make 24v) http://goo.gl/rCXciW 3U 19" Inch Rack Mount Shelf For Pro Audio and Computer Networking http://goo.gl/SJQ6DP MikroTik CCR1016-12S-1S+ http://goo.gl/h5N4RQ 6 Port Rack Mount Fiber Enclosure Pre-Loaded with SC SM Connectors http://goo.gl/8x5fcg The 4x batteries fit on the 3U tray and take up just under 4U of total height. There is enough room in the 12U rack for up to 2 of these 4U battery trays. The MikroTik is all SFP ports because we run fiber to everything, with the exception of one copper eth cable to the rectifier for battery management and monitoring. Incidentally the Mimosa B11 backhauls will accept the BiDi SFP transceivers linked on the SMM Details.PDF parts list, provided they are HP compatibility. So we use the switch to power the B11s and then it’s fiber goes directly into the fiber patch panel (fiber run in liquidtight from enclosure). The CCR1016 then has all the backhauls directly connected via fiber, and the APs are grouped 8 APs per switch (per fiber) so for every 8 APs there’s a full gig to the router. (You could have 12 APs per switch if you added 6 SyncInjectors total). The enclosures are standardized so we are building to have hot spares on standby ready to go in the event of a catastrophic failure.
