Wait for it.... (CMM)

Just wanted to give a heads up on our experience with our first run at
trying ePMPs at this distance of cable run.
We mounted 4 5 Ghz and 4 2.4 Ghz ePMP APs today (a retrofit from
100 series APs). We have an existing CMM Micro that has been at the
tower for 5 or 6 years. We needed more ports with Sync so we
attempted to use a Gigabit Syncinjector for the additional ports we
needed. We put the 2.4 Ghz radios on the CMM and put the 5 Ghz on the
SyncInjector.
The CMM and the "LAN facing" ports on the Syncinjector, powered by the
same 5 AMP/24v power supply that we use for CTM's, plugged into a
2011 Mikrotik router.
The CMM works flawlessly, providing 100Mbit connections and sync .
The SyncInjector... not so much. Initially, the symptoms were that 1
of the APs would only connect 10 Mbit and 1 different one would not
get Sync. We tried swapping know good (successful on the CMM)
cables, changing ports on the SyncInjector to make sure we didn't have
cable or AP related issues etc. Eventually, we lost ability to do
Sync on any of the APs, and 2 of the 4 will only do 10 Mbit. Tried it
with both 100Mbit and Gbit ports on the 2011, in auto or static
Speed/Duplex configs. No go. The cables being used were both
Best-Tronics and Toughcable Carrier. All the toughcables were premade
to the 300 feet and tested inhouse at Gigabit speeds (TIK to TIK tests)
Going to have to climb again tomorrow with a second CMM to swapout for
the SyncInjector.
We normally have very good luck with SyncInjectors but at 300 feet
distance with the Gigabit models, we couldn't make it work in this
application. Cambium had "advised us" that there may be abnormal
challenges with 300 ft. of cable on the ePMP.
