SV: [nslu2-general] Re: NSLU is making high frequency noise
- Hi again,
This coil is probably a part of a DC/DC step down converter, to generate a
lower voltage than 5V.
It could be a mechanical fault on the coil, that makes it vibrate when the
DC/DC converter is running chopped DC current through it.
Maybe try add a small droplet of glue if you find any part of the coil that
is responsible for the noise.
Is your NSLU working normally except for the noise?

Well.. thanks for the suggestions. I guess, i have found the source of the
I'm pretty sure it's one of the coils, like Hendrik said. When i touch the
L2 coil with a screwdriver, the sound goes absolutely insane..
So now i wonder, is the coil bad, or could something be causing this
L2 is on the left center (marked 220 on top)
What are these things for?
