I expected a 600SS to have the isolate/ground option at the ground screw location. The older 300SS was a much worse design. I also seem to recall there was a major improvement to the 600SS around Rev. C or D, but that is a long, long time ago, I don’t remember the details.

My most recent batch was purchased this year. It says Model 600SS, P/N 600SSD. The board shows (c) 2008, so this could have been old stock if they have a newer 600SS revision.

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 <[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?
