Just got a call with a customer complaining that the dx80 unit itself was sounding a loud humm. They said it just started happening and that it was only the switch, not the phones. Any one ever come across this before?

Overloaded power supply, bad filter capacitor, loose laminations in the power transformer or loose transformer mounting, bad fluorescent light ballast, bad neon sign transformer, take your pick.

Cap, I have a whole power supply board here from a switch that the cpu was water damaged, I know the PS is ok if you want to try it. Ping me if you do. I keep it in a crash kit. If it works you'll know what you need, if not, what you don't need.

If you have the hard drive version voice mail in that one then i would also check the cooling fan, Have had several that the fan goes bad and causese some nasty sounds that are not pleasant to the ear.

TELCOM hit it! It was the VM's fan, disconnected it ...problem solved.
Mark, thanks anyway.

Here I thought it just didnt know the words

you might want to replace that fan.

I plan on replacing the fan. This guy doesn't want to shell out anymore money than he has to. It's in a climate controlled room so it should be ok for now.

We had that problem on a DX80 with the HDD VM that had a fan. It started making bad noises. We replaced the fan. All was right with the world. Nice how it's so easy to make things right with the world, isn't it?
