We just got a new 5505 1 week ago. Upon plugging it in it has a very high pitched noise. Similar to the sound you get when your ears are ringing or a cricket but its constant.
This drives us nuts. Any ideas what it can be since there's no fan or moving parts I can't figure it out.

It might be the power supply. Have you tried replacing it?

sounds like the switch mode power supply isn't running fully.
does it do it if you just plug the PSU in but don't connect it to the ASA? or is it just under load of the ASA being connected?
either way id put in for a replacement as its not good
