I would like to reconfigure the default Ethernet switch on a 750G to remove all ports from the switch.

I consistently kick myself out of the RB750G by playing around with reassinging master port.

What's the deal?

You can do And default configuration will not be applied after reset. Also you can simply reset configuration and choose to remove configuration when you get prompted.

I managed to get it working by dancing around the config.

When it resets, does it reset without the ports as part of a switch?

No, unless you specify Also after each configuration reset RouterOS will prompt you after first login whether you want to save default configuration or not.
