Who among us hasn’t tried to cram a Change Order out on Christmas morning before the family comes over, only to catch that you designed a nice residential network with all PoE devices, but the rack was moved to a bedroom closet 10 feet from a bed.. a 48 port PoE switch will be jamming fans 24/7 at almost 40dB at 80% capacity…

And you realize you can do a fanless 8 port PoE switch with a 24 port managed fanless switch to kill the fan noise. So there will be 12 wall warts for field PoE devices, but it will be quiet!

Happens all the time.
