Not user changeable jumpers are black. Before this jumper plug installation/setting, please use ESD protected cushioning material for safer operation. The following jumpers are accessible for the user (use green jumper plugs, as for J2 use blue jumper plugs): SCSI ID setting jumper J2 SCSI bus parity jumper JP2 Terminator power on/off jumper JP7 Write protected jumper JP9 Motor Auto-start option jumper JP2 Synchronized spindle jumper JP2 Synchronized spindle Terminator JP6 Synchronized spindle signal connector J3 Note: The DK517C jumpers other than listed above are installed by the manufacturer (black jumper plugs) and must not be modified or replaced by the user. These settings are unique to each PCB.

Mounting -------- In order to assure shock protection ability, design the cabinet of a system as described in this section. - Mount the drive with four screws by using the proper 4 screw holes (total of 8 holes - 4 side, 4 bottom) of the drive. - The insertion depth of the mounting screws below the drive surfaces must be less than 3.5mm (0.14inch) for side holes 5 mm (0.2 inch) for bottom holes Sequential Activation of Motors ------------------------------- When multiple disk drives are connected and turned on simultaneously, a large amount of current will flow. It is recommended to turn the motors on one by one at an interval of approx. 35 seconds. Indication of "READY" on the last drive reports that all drives have been activated.
