We're looking for Sx 220, Sx250, Sx350 and 550 switches. The stencil pack on that download page dates from 2014, and is severely outdated, and only has the Sx300 and 500. Cisco - no update?
I have an SG300-28PP and a Netgear GS105PE. I cannot get PoE+ (802.3at) working from any port on the SG300. I tried with CDP on and off, and LLDP on and off. Both switches on latest firmware as of the date of this post (Aug 20, 2016).
