[Tfug] Why do they whine?

[erich]

Hmmm,
         I didn't think of that. If it has a cheapy switching power
supply its quite
possible that there would be a noise.  Iv'e noticed the noise comming from
other network installations. In a commercial setting there probably
aren't that
many complaints about noise, because network gurus don't typically sleep
overnite with their gear.

                                                                                    
Thanks,
