switch dont restart by themselves without command, first remove the switch from the network, disconnect from internet, make sure you hadn't fired anybody recently it sounds like a hack. reduce network traffic to local area only and priortise important internet traffic. now got back to the switch and troubleshoot make to check the reboot command on error or when error is found, if the problem stops when the switch is remove somebody is messing with the network.or the darn switch is faulty install a new one.

The resetting of the password requires the installation of a console cable to the console port.
Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.
Use the included cable, or be sure that the pin-out complies with a standard null-modem cable
Once the cable is connected, reboot the switch. Type a Ctrl/C until you enter the failsafe mode. This will be denoted with the prompt: “CFE>”
At the prompt execute the following commands:
CFE> reset -sysreset
At this point the password has been reset.
