Actually, what you shouldn't do is connect a powered-up device to the bus
(it may be trying to drive the bus at that particular moment). Inserting a
dead device could insert some noise on the lines, so the bus should
preferably be quiet. On sparc:s this is easily accomplished by breaking
into the prom while you connect the device. If it is an external device,
you have the termination which probably needs to be moved. If, on the
other hand, the device is connected to a pass-through connector, there
really shouldn't be any problems.
