See the diagram? Far left, straight over from the jumpers.
Left to right: Source A / +7&8 / -4&5 / nc3&6 / nc1&2
Set 3&6 to + and 1&2 to -
Connect +48/56VDC to PowerA, negative/return to common.
You must leave it -4&5, +7&8 if you expect to provide sync over power to
a 450i. The radio will not see the sync pulse if that traditional Canopy
polarity isn't retained. The 450i doesn't necessarily need the other two
pairs, unless you're using POE out from the Aux port where you might
need the additional 25W. I've never used that, so I haven't bothered. It
runs fine on two pairs.

This is what the jumpers are out of the box. Lets see if I got this
right. From Left to Right 7,8 +, 4,5+, Skip, 3,6 Nada, 1,2 Nada
I'm totally confused. I thought 4,5 should be - and 7,8 + for Mode A
Passive POE. Ugh, not enough coffee to get it.....
Please help....

Forrest,
Please forgive me for my ignorance, but what jumpers are needed to
make this puppy gigabit for the Cambium Medusa? I see: Pin 1 Upper
2, Pin 2 Upper 2, Pin3 Bottom 2, Pins 4 and 5 Upper1
Or is there documentation on how to set these puppies?
Thanks
Sam

with Medusa
OK, so grounds are related to the problem.
There may be something unusual with timing pulses on the
power that is
causing the surge suppressor to fire.
Forrest would know much more than I about that.
I honestly don’t know if anyone has tried my product with
a Medusa before.
I have a 100% gas tube version that may solve the problem.
I am still having some troubles with PTP450i holding 1gbit
ethernet
even with Cambium sync. Not near as bad with Cambium Sync though.
Will these gas tube versions work any better? Will they still keep
equipment safe?
