There is one switch labelled "on/off" on the rear of the router,
that will work miracles, when operated ...
When i was testing routers and had multiple of them in my office i
noticed Cisco routers to be the loudest of them all, due to this
enormous noise their fans produce. I actually had to switch them off
each time i wanted to phone. I still don't know where cisco buys these
buzzers. Maybe these are remainders from scrap aircraft turbojet engines.
Incredible.
If you really need some kind of "Desktop Router", you should probably
look for other vendors routers, or put the cisco in a machine room,
where it belongs, and where it will quickly become comfortable
amongst your remaining growling equipment.
(You never knew, why they insisted that you really bought a BRouter ?
it's simply an abbreviation for "Buzzing Router").
Hey, Cisco, how about it: In the next release of the environmental
card firmware: An SNMP variable through which you can control the speed
of rotation of the squeakers, or at least a variable that gives a
reading of the noise level around the router - this could be used
to activate an alarm at the NMS if the noise level starts drowning
out the nearby airport !
You could also try installing a second AGS and tune both of them,
so that the wind mills run in sync, eliminating each others noise.
Thats something that we practise very succesfully. Well... at least
we cannot identify which router the noise comes from anymore.
(i think that's the solution that cisco would prefer to sell to you)
Still other people try hard rock as a remedy.
Actually there is a very simple alternative to this all, and it is
to buy fans really designed for office use and exchange them for
these infernal built in noise generators.
If you fail to improve your situation in the long run, you may consider
joining the A.D.C.U (anonymous deaf cisco users).
