I purchased a used TS-8VHL unit and the admin password was changed. I tried the reset method with the red button found under the main display. I held it down for 5, 10, 20, 30 seconds, every time it just reboots the machine and the IP and password are the same (i.e. not reset back to a default state). I tried holding down the function button and this did nothing. I have no way to get the old admin password. I don't care to save any data on the drives. Is there a nuclear option to just get the thing working?
