I could have sworn that the first run of 450i SM's were good old 30v canopy power supplies. Am I out to lunch on this? I think the 900 450i sm is still 30v, but the spec sheet shows the 5 and 3ghz sm's as 56, just like the APs.
If it did change, does anyone know what mac address or part number differentiates them?
Aha... I figured it out. I had a 450 High Gain integrated 3ghz radio I was looking at (more accurately, a colleague had in another office). They look identical to the 450i integrated radios but still the same old 30v radio in the 450i shell. I forgot they were a thing to be honest.
