According to this, you should be able to reach the system console through the SER MGT port: https://unixed.com/index.php/2013/06/16/accessing-the-sparc-system-console/ NET MGT is probably easier, but you'll have to set it up first. Perhaps you can also attach a USB keyboard and press the break key to get into the system console, then type "reset" to boot the machine? Not sure if this works without a monitor though. And you might need to enter the system password first, if it's set.
