Now for the 450i, didn't Forrest say something about them not liking the
sync from his SyncPipe?

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.

I considered those but they're not gigabit, correct?

Oh, yeah, that was you! That makes sense. 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'm the guy who just smoked a ring of FSK APs by running 48v
to them! :) I wanted to use 48v for the reasons you just
stated but because much of the Cambium equipment is only 24v
this meant having a DC DC converter in the enclosure which is
another point of failure, expensive, and impractical to step
down large wattages. 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,

Interesting that you are using 24V and not 48V especially
since you are running DC up the tower where voltage drop may
be a concern. 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.
Thanks,

Thanks! 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.
I was asked offline about what DC/fiber we’re using:
1000’ 12/4 SOOW SO 600V Power Cord http://goo.gl/mKVXG1
Armored outdoor OS2 singlemode 9/125 6-strand fiber,
Male SC UPC Simplex to Male SC UPC Simplex,
