I have a brand new MARS that I took it our of box couple days ago. I keep hearing two short beeps and 4 short beeps. However, the system is working fine as far as I know. I'm still doing the configuration. Does anyone know about this beeps? I believe it is something hardware related issue.
Sounds very similar - I ran into the same situation and it turned out that the fans were wired opposite than normal. Needed to issue an rma to get a new box.
