Model: DPSS-336950, 318350, 309170

Ultrastar 36LP models have two jumper blocks, J4 and J6, which are located on the logic card as shown below.  68-pin models also have an auxiliary connector.  A detailed description of the jumper signals is available in the functional specifications.

See the following topic for additional installation information:

68-pin auxiliary connector

The 68 pin models have an auxiliary connector between the power connector and the 68-pin SCSI connector that replicates some of the functions contained in the J4 and J6 option jumper blocks.  Either the option jumper blocks (J4 and J6) or the 68-pin auxiliary connector can be used but do not use both.

SCSI address settings

The SCSI address of the drive is specified by installing jumpers on Jumper block J4 pins 7 and 8 (ID bit 0), 9 and 10 (ID bit 1), 11 and 12 (ID bit 2), and 13 and 14 (ID bit 3).  The auxiliary connector can also be used to specify the SCSI address for the drive.

Notes:

1. SCSI address 0 is the shipping default for 80-pin models.
2. SCSI address 6 is the shipping default for 68-pin models.
