The GIGE SS was redesigned due to some C5 issues. If you get one that says REV C on it it should work.

Maybe I was sent a standard voltage model of your GigE SS, but I had Ethernet link issues with it as well. I ordered the HV model, but didn't see anywhere it said, so I assumed the disty sent the wrong item. Maybe the HV would work fine.

A few of my earlier designs didn’t have them but I added them. The old 100 Mbps motorola design was not too bad for its day. It is similar to my 444 design but I have the test port and the voltage and load LEDS. If you are doing SMs the test port is pretty handy. The newer cambium design and my latest design are very similar in surge circuitry but they add a whole bunch of components (all the small components at the top of the board) that are related to automated testing and I think perhaps extracting a little POE to light a LED. I think the LED is right above the ground mount pad. There is an LED there, just not sure what it does. Does it light up when POE is applied? In any event the extra non surge circuitry adds some parasitic loading to each data pair (Like 7K transverse metallic loading) and provides additional failure paths. It does not have a gas tube and will allow super large impulses to pass. The Mimosa only has gas tubes. They do have a certain delay in ionization. I prefer to use the solid state picosecond acting components as the primary line of defense followed by the gas tube. Belt and suspender approach.

I've got the old 100Mbps 600SS on the left, the new 1Gbps Cambium in the middle, and the new 1 Gbps Mimosa on the right. I didn't have the 1 Gbps UBNT unit, but it is the same electrical design as the Mimosa unit. To address the original question, the ePMP PoE surge protection is just spark gap (on the 100 Mbps units, I never opened a 1Gbps unit). I'd be inclined to keep using a surge suppressor, despite the additional install time. -Chris On Sat, Jun 25, 2016 at 8:41 PM, Paul McCall <javascript:_e(%7B%7D,'cvml','[email protected]');> wrote: Just noticed that Cambium has a different surge suppressor. We had purchased a large overstock of 600SS for cheap, and are almost running out. I am probably a bit spoiled on having not paid much for the surge protectors, so am going looking. These are mainly for use with ePMP SMs. We use Beehive protectors for APs So, Cambium’s site has these… C000000L033A http://s3.amazonaws.com/cambiumstatic/assets/55aeb0aceb1db13311a99ff0/GigabitEthernetSurgeSuppressor_Dec2015.pdf?download I have heard some people say that the POE provided with the ePMP SMs included surge protection, therefore negating the need for a separate surge protector. What sayeth the crowd?
