[asterisk-users] Quiet 24 port POE gig switch

[Singer XJ Wang]

Honestly, how are you guys expecting a 24 Port POE to be fanless?

Lets start with some logical points here:

1) 24 Ports x 15.4W/Port = 369.4Watts + Switch Power = ~400Watts... now 
Power Supply isn't that efficient so you're getting probably a 500Watt 
Power Supply (assuming 80%)...

2) with a 1U chassis, you can't blow air up or down... only front and 
back.. so you're stuck with a 40mm fan..
