Jumper Setting
==============
x = Default setting
The following jumpers are accessible to the user
Jumper Pins
SCSI ID setting jumper J6 1 6
SCSI bus parity jumper JP2 7 8
Terminator power on/off jumper JP3 1 4
Terminator Enable/Disable JP3 5 6
MOTOR START/STOP setting jumper JP2 5 6
SPINDLE Synchronize JP2 1 4 and

It is permissible to install the DK315C horizontally or vertically
as above.
Mounting
--------
Mount the drive with four screws by proberly inserting them through
4 holes in the drive. (Screw's torque: 6 8Kg-cm (2.36 3.15Kg-inch)
Clearance not less than 3mm around HDA is required to accommodate any
possible vibration of HDA itself.
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. 20 seconds. Indication
of "READY" on the last drive reports that all drives have been
activated.
