-
- 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).
