While I can't answer that particular question, have you considered passive noise reduction techniques such as reorientation / relocation? Sometimes just turning a component 90 degrees (horizontally or vertically) can reduce the perceived noise... Then there is the option of using some kind of enclosure... Usually enclosures can reduce noise greatly while not significantly impacting cooling (such as a wall-mount cabinet.) Also, the use of noise absorbing materials can help. (google for acoustical panels and acoustical foam) Obviously, locating equipment like this in a quiet workspace is not ideal... ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I suspect any 24port will have a fan. The Netgear FSM7326P are not too bad and we have had good luck with them. ps - I also load their open source software.

Re: [asterisk-users] Any quiet 24 port POE switches out there?
We bought 7 switches, and 3 of them failed after one year. It took quite a bit of doing to get the off-shored customer support to read their own literature to cover one switch under warranty. Never could get the other two covered... When I got the warranty status updated, they told me to reload the flash and call them back. When I called back, they had lost the incident. I gave up, threw them away, and bought the linksys 24-port PoE switches. Haven't had a single hiccup from those...

RE: [asterisk-users] Any quiet 24 port POE switches out there?
High end Cisco 24port PoE switches make noise too but at least they have a variable speed fan so if your not loading the switch the fan will run quieter. It's still gonna be noisy for running on a desktop near people. No way around it. Any 24port PoE switch will need a fan and make lot's of noise. I would look for something that has a variable speed fan so if your only using a few ports as PoE it will be quieter. If you don't need 24 PoE ports then go for the lower PoE port options mentioned -Original Message- From: Anselm Martin Hoffmeister [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 03, 2007 4:25 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Any quiet 24 port POE switches out there?
