 J1 and J2 are fabricated from one 50-pin connector. J1 has 40 pins,
 J2 has 8 pins, and 2 pins have been removed at the boundry between
 J2 and J1.

 Jumper Setting
 ==============

 x = Factory default


 GoDrive GRS 80/160 S drives have a single 2 x 25 connector (on 2mm
 centers) for both power and data. The connector also includes four
 pins which are used as factory test points (these pins must be
 allowed to float), for the SCSI device ID (J2 pins 5 through 7), and
 for a drive activity LED (J2 pin 8).

 The drive will operate in all axis (6 directions).



 Dimensions and Mounting
 -----------------------
 The drive can be mounted in any orientation. Maximum screw penetra-
 tion is 3 mm with a minimum penetration of three full threads. The
 maximum mounting torque for these screws is 40 inch-ounces.

 NOTE
 For optimum drive performance, the system mounting method should not
 result in any disortion or twisting of the drive's base casting. For
 example, if the drive is attached (via its bottom mounting holes) to
 a stiff mounting surface that does not meet the GoDrive GLS flatness
 requirements of 0.01 inch, then head switch times may be degraded.

 The threaded holes in each of the four corners of the GoDrive GLS are
 for top cover attachment only and should never be used for any other
 purpose.


 Cable Connector
 ---------------
 GoDrive GRS 80/160 S drives have a single 2 x 25 connector (on 2mm
 centers) for both power and data. The connector also includes four
 pins which are used as factory test points (these pins must be
 allowed to float) for the SCSI device ID (J2 pins 5 through 7), and
 for a drive activity LED (J2 pin 8).

 The recommended system mating connector is a 3M Series 150 50-pin
 connector or equivalent. The maximum cable length is 18 inches. The
 maximum cable length is 12 inches. To assure that the system cable
 connector is installed with the proper orientation, plug Pin 17
 hole on the J1 system connector.
