[asterisk-users] Quiet 24 port POE gig switch

[Jerry Jones]

You will have a hard time finding a 24 port POE without fans - too  
high of a power density. Do you really need 24 ports? perhaps a 12x12  
otherwise multiple 8 or 12 port models may work

Do let us know if you find a 24 port without fans.
