Lately I have noticed that when downgrading a 500v2 out of the box from R8 to R7, you cannot log into the box anymore. Manager/Manager, Administrator/password, Administrator/Administrator all do not work. When I try to reset the security settings, the security login does not work either. I just end up having to hold the reset button on the back for 35 seconds. It's rare that a downgrade from R8 to R7 would even happen, but I saw it for the 3rd time today and wondered if anybody else had noticed it. Maybe I'm just crazy
