[cisco-voip] Quietest router for CME

[Matt Slaga (US)]

You could get an AGS+.  That thing only had fans about the size of your
heat pump outside.  In fact, it could probably replace your heat pump.

The UC520 I had on my desk at work for a month had fans in it....

	The UC520 SBCS does not have any fans so it is relatively
silent.

	Turn your AC way down,  and the fan on a 1841 will run at low
speed.  I recall the temperature sensor in environmental monitor adjusts
fan speed just like my laptop does. Stick it in a closed cabinet and it
should run at high.

	 

	I want to say the old 1751V fan rarely ran and you could
disconnect it's plug from chassis, but you don't want such an old router
for CME.

	 

	You could also cut the fan wires and let it run hot.

	Chassis Ventilation 

	An internal three-speed fan provides chassis cooling. An onboard
temperature sensor controls the fan speed. The fan is always on when
power is applied to the router. Under most conditions, the fan operates
at the slowest speed to conserve power and reduce fan noise. It operates
at the higher speeds when necessary under conditions of higher ambient
temperature.

	What is the quietest router possible that supports CME?   I want
to run CME at my house but prefer to keep the fan noise to a minimum. 

	 

	Thanks,

	Mark
