Jumper Settings

J1 is the fifty pin scsi connector with pin 50 at the outside and pin
2 close to JP6.

Jumper JP6 at the back of the drive between J1 and J3 looks like:

        9 7 5 3 1
        + + + + o
        + + + + o
       10 8 6 4 2

This is how it is shipped from the factory. ++ indicates jumped, oo
indicates open. Since you say that all of these are open, this is your
problem:
   9/10 determines Motor start with power - no wonder nothing is happening
   7/8  determines parity - odd parity enabled is the default
   5/6  determines bit 2 of the SCSI ID
   3/4  determines bit 1 of the SCSI ID
   1/2  determines bit 0 of the SCSI ID
That is, it is shipped from the factory as SCSI ID 6.

 +--------+----------+-------+-------+-------+
 |SCSI ID | Priority | 5 & 6 | 3 & 4 | 1 & 2 |
 |        |          | (MSB) |       | (LSB) |
 +--------+----------+-------+-------+-------+
 |   0    | Lowest   |OPEN   |OPEN   |OPEN   |

The terminating resistors are the three eight-pin packs U40 through
U42. These must be oriented with the dot towards J3 for the disk drive
to work properly (assuming the drive is terminating the scsi chain)

Jumper JP9, near JP6 and oriented at right angles, determines whether
the bus is single-ended or differential. For signal-ended signaling,
jump 3/4 and leave the others open. For differential, do the reverse.
On the other LXT drives, 340/437/535, this jumper is called JP7.

This will get you going. Here is a little information about the drive:
