In 2001 my first IT tech job as help desk analyst I heard beeping in the server room on one of the Solaris/Oracle machines and pressed the power off/power on button on the chassis. DBA came running in and I promptly left saying "oh I think it rebooted itself". The company went bankrupt shortly after so no huge lashing came my way but all my more experienced friends where like "wtf never do that again!"
Was probably a program running beep codes, haha. I have also had servers executing beep codes that brought great anxiety to me for endless hours. Turns out it was just some debug alert calling the motherboard speaker beep.
