RA70s have a switch block, on which you set the unit number unless you
have a front panel. Any other RA7x drive needs a proper front panel, or
the unit number is zero.

You can put RA7x drives in a box the same size as an RA9x drive, which
comes with a front panel for four drives (which is the number you can fit
in the box).
