Is that an M9715 board plugged into the backplane between the CPU board slot and the power supply, or something else? Or is there a cable plugged into the DSSI connector on the M7624 KA640 adjacent to the memory bus connector that plugs into a some board and stops there, and then another cable from that board to the DSSI drives? Do the DSSI drives plug into the backplane, or do they have cables connecting to them?
