Wow! Is that an “450d production stops as soon as the high-gain 450b is put 
into production”, or “they stopped making them already” situation?

FYI...the 450d is EOL. Announced earlier this week. Found this out while trying 
to order more.

The 450d is a standard 450SM board. Canopy POE polarity only. So yes, you'll 
need to reverse the blues and browns at one end.

The 450b, Force180 and Force200 are all polarity agnostic.

Is anyone else powering a 450d SM with a Netonix? I'm wondering if I need to 
reverse the polarity on the cable like we do with 450 SM and AP. Looking at the 
spec sheet it just says INPUT VOLTAGE 20 TO 32 V which makes me think it can 
take a straight thru cable.
