Hi I've had the same issues before with other routers.
This was a 3845 and at the time we couldn't find any way to reduce the noise, but found that if we installed small cooling fans into the small cabinet they were in, we could reduce the amount of time, (if not eliminate) that the router was on its high speed fan setting. Try looking at a 2911, not sure what your performance requirements are, but it was designed to be 2ru tall so they could fit larger (therefore quieter, due to lower rpm) fans.

I've got one that will be deployed in an office space and I'm going to hear about it if I don't do something. Show environment says that it is a quiet as its going to get, but the fans are really loud still (much louder that the 2821 it is replacing) SYSTEM FAN STATUS ================= Fan 1 OK, Low speed setting Fan 2 OK, Low speed setting Fan 3 OK, Low speed setting Fan 4 OK, Low speed setting SYSTEM TEMPERATURE STATUS ========================= Intake Left temperature: 25 Celsius, Normal Intake Right temperature: 27 Celsius, Normal Exhaust Left temperature: 32 Celsius, Normal Exhaust Right temperature: 32 Celsius, Normal CPU temperature: 54 Celsius, Normal Power Supply Unit temperature: 26 Celsius, Normal Thanks, Erik _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
