We really depend on a power-cycle to speak of "harmless".

The procedure would be

Anything else would NOT be harmless, as you might end up with two CPUs trying to access the bus. This feature came extremely late in the development, and the CPLD (the main logic chip) knows nothing about the state of the switch/jumper. It can only deduct the information "030 active", but it cannot deduct the information "030 inactive".
