In multidrive configurations, it is necessary to configure each drive
with a unique address. A maximum of seven drives are permitted per
single host controller. The address for the drive is determined by
installing the jumper plug in the appropriate jumper location.
As shipped from the factory, the drive is configured as logical unit
number one. Removing the jumper entirely is equivalent to a "no
select".

 JP6  Option for Sequential Spindle Motor Spinup Jumper
 ------------------------------------------------------
    x JP6  CLOSED  The drive automatically spins up as soon as power
                   is applied.
           OPEN    The drive is started be issuing the appropriate
                   command from the controller.

The spindle motor spinup jumper allows a string of drives to be
started sequentially by the controller.

 JP14  Write Protect Selection Jumper
 ------------------------------------
      JP14  CLOSED  The drive is write protected and can only be read;
                    no writing may take place.
    x       OPEN    The drive is not write protected.

JP16-JP31 Hard Sector Configuration Jumpers
--------------------------------------------
Jumper JP31 selects the mode of operation. Jumper JP31 installed
configures the drive as a soft sectored drive; removed, it configures
the drive as a hard sectored drive.

Jumpers JP16 through JP29 allow the user to configure the drive's
hard sector size. The sector size can range from a minimum of 123 to
a maximum of 10,470 unformatted bytes per sector, with 1 byte
granularity.

The hard sector configuration jumpers are encoded in a binary
fashion, with JP16 being the least significant byte and JP29 being
the most significant byte. An installed jumper equates to a one.

Jumper JP30, if installed, enables setting the hard sector size over
the ESDI interface. The drive must be in hard sector mode, (i.e. JP31
removed).

Jumpers have been provided to allow the number of usable data heads
to be selected. In order for the drive to respond correctly to the
request configuration command - number of heads, these jumpers are
set at the factory to correspond with the model of the drive.

Mounting
--------
The drive may be mounted in any orientation. In any final mounting
configuration, ensure that the operation of the three shock mounts
which, isolate the base casting from the frame is not restricted.

Mounting Holes
--------------
Eight mounting holes, four on the bottom and two on each side, are
provided for mounting the drive into an enclosure. The size and
location of these holes are identical to industry standard floppy
drives.

Caution: The casting is very close to the frame mounting holes in
some locations. Mounting screws lengths must be chosen such that no
more than 0.125 inch of the screw is available to enter the frame
mounting hole. The torque applied to the mounting screws must be
between 9 and 12 inch pounds.

J1/P1 SCSI Connector
--------------------
Connection to J1 is via a 34-pin PCB edge connector. The pins are
numbered 1 through 34 with the even pins located on the component
side of the PCB. Pin 2 is located on the end of the PCB connector
closest to the DC power connector J3/P3. A key slot is provided be-
tween pins 4 and 6. The recommended mating connector for P1 is AMP
ribbon connector P/N 88373-3 or equivalent.

J2/P2 Connector
---------------
Connection of J2 is via a 20-pin PCB edge connector. The pins are
numbered 1 through 20 with the even pins located on the component
side of the PCB. The recommended mating connector for P2 is AMP
ribbon connector P/N 88373-6. A key slot is provided between pins 4
and 6.

J3/P3 Power Connector
---------------------
The DC power connector, J3, is a four-pin AMP MATE-N-LOCK connector
justify margin P/N 350543-1 mounted on the solder side of the PCB.
The recommended mating connector is P/N 1-480424-0 using AMP pins
part number 350078-4 (strip) or part number 61173-4 (loose piece).

J4/P4 Ground
------------
The frame ground connector is a Faston-type connector, AMP part
number 61761-2. The recommended mating connector is AMP part number
62187-1. If wire is used, the hole in J4 will accommodates a maximum
wire size of 18 AWG.

 J6/P6 Auxiliary Connector
 -------------------------
 The auxiliary connector is a Berg 68451-121 ten-pin connector. The
 mating connector is a 3M 3473-6010.
