Supermicro X7SBE with Chenbro 16 bay 4U case

[Dan Carroll]

Hiya All,

I have the above gear with an Areca 12 channel card in it.    It's 
getting on and I'm getting a periodic loud beeping from it.   When it 
starts it beeps for about half a second and repeats every 15 seconds or so.

If I shut the system down totally for a few hours the problem goes away 
only to reappear days, weeks or months later.
Nothing in the freebsd logs and saw nothing in the bios.   Nothing in 
the Supermicro manual either.    The system appears fine otherwise.

Anyone have this gear and seen this problem?
