I'm pretty sure it is the POE. The problem shows up on the spectrum analyzer as
soon as the POE ports power on. Before the radio has even the remotest chance
of fully booting up. I'm not sure however if that would be the case if the
radio was not even on the other end of the cable that had POE

This is correct. Harris Microwave Communications Division (MCD) was spun off

Do you know what frequency the 911 radios use? I'm guessing these are VHF 2way
radios?
Closest thing I can think of that I've run into is customers who are also ham
radio operators, or with OTA TV antennas and interference into low band VHF
channels 2-7. I didn't have much luck with shielded

I would first attempt to discover if it is the CAT5 or the radio itself.
Ask the 911 guys if they have a spectrum analyzer they can lend you to
puzzle this out.
Shielded CAT5 helps.
Putting in coils at the ends helps.
Ferrite chokes help.
Some run it in liquidtight or full metal conduit.

We've had problems with the RF screwing up ethernet, but if the there was
any interference the other direction, nobody ever told us about it. Ferrite

I am in town with Harris, they spun off/ divested quite a bit of those
divisions to Aviat, Speedcast, Stratex, Caprock. They still build radios for
mostly government systems under their Govermnment Systems Division & rebuilds
of old systems. You can contact Star microwave and see what

And in 5 billion years the sun will be a red giant and all life on earth will

But the good news is, that half the depleted uranium that we will be storing

other half will have decayed into non
You can kick them back to timing over power using telnet.
Just telnet to the AP, and issue "synconboard off" wait a second and
then issue "synconboard on"
It's best to first make sure it sees the other source on the "Home >
Sync Status" tab.
Good luck,

I have 8 Canopy 450 AP's all receiving sync and power from a RackInjector.
Last night 3 of the 8 AP's lost sync and rolled over to On-Board GPS. Only
a hand-full of SM's re-registered on 2 of the AP's. Sync loss happened on 2
different cards, not the same card. Looking in the RackInjector logs,
I'm looking for a Zoho consultant to manage a migration project for a customer.

What marketing I've seen of them lately sounds impressive, but they don't
really take me seriously when I try talking to them, so I reciprocate.
