So I'm *almost* sure that you can run one without
the OCP. Mind you, it
might have been an RA71 or RA72 rather than an RA70.
Right now I cannot put my finger on a suitable manual ...
There are, I'm sure, some jumpers or switches that set the unit number.
There is a DIP switch on the back next to the Fault and Ready LEDs
that is labeled Unit Number Select. Next to the DIP switch is a
pushbutton labeled Unit Number Accept. I have all of the DIP switches
off, I suspect for Unit Number 0. I tried pushing the Unit Number
Select push button both after the drive was powered up and while it
was being powered up. It does not spinup.
