I can only speak for the two SE/30 boards I have before me. The fuses are unlike conventional ones in appearance. One style is a surface mount rectangular metal plate sandwich, the other looks identical to a molded case cylindrical axial lead plastic capacitor without body markings dull yellow-orange color, through hole mounted with leads. My SE/30 boards both have a coordinate marking system silkscreened top side along the front and PDS connector edges, and the fuse is between location L12 and L13, marked F1. It is between the filter inductor package and the board edge along which the PDS parallels. And yes, I have verified with an ohmmeter and by following the traces to the filter inductor that this is how my SE/30 ADB connectors get +5.
