Please log in for more thread options This is slightly off-topic, but applicable (I think) ;-) Where I work, we recently built a 1million $ a/v center. Inside, there is a Cisco Catalyst Switch (4U?, I don't know the model number at the moment) which is VERY noisy. I've been asked to find out about quieting that switch down. Though I've NEVER heard of doing that before, I understand why as it would interfere with some of the audio production people. In any case, obviously the entire telco rack could be encased, but that would present other problems (ventilation). My thinking is there must be a way to replace the fans, as those are the noisy components. I will of course ask Cisco - I need to find our Service Code number, otherwise they won't give you the time of day. In any case, I wonder if anyone here has run across this scenario and what suggestions you might have. Much appreciated. | |||||||||||||||||||

Please log in for more thread options FWIW, I needed to put a Cisco switch in a high tech conference room. It roared when on the bench. I tried it before I went to spend more money. I put behind a partition and when people were in the room, you couldn't hear it. YMMV. -- a d y k e s @ p a n i x . c o m Don't blame me. I voted for Gore.

I guess I would have insisted on a closet for network gear rather than it being out in the open if noise was ever an issue, since almost all network gear is noisy, and seems to getting worse over time. I've seen people do seperate exhaust feeds just for their enclosed network/sever gear. Put some dense foam on/around the door, and you get pretty quiet. I don't think replacing the fans are going to do much for you. My 450x switches have loads of fans on them (11 I think for a 4506 counting the power supply ones?). Cisco doesn't have a silent kit for their gear, they expect them to go into closets or data centers. | |||||||||||||||||||

We had a situation where an integrator placed a switch in a transit case for us, the fit was to tight, and it ended up warping the chassis of teh switch by the time it was shipped to us. | |||||||||||||||||||

Can you run flexible ducting to the fans? If so you route these away from where

Just a long run to another corner of the room can absorb a lot of noise. Just oversize the duct within a foot or less of the switch to make sure you aren't adding extra load on the fans to push or pull air through the ducts. Also if noise is being transfered to the rack try nylon bushings or even putting it on a shelf with rubber feet. Cisco need not be involved and your warranty would stay intact. :) David | |||||||||||||||||||
