Jumper Settings for the Quantum SDLT320


The SDLT 320 has three configurable options that may require modification based on user requirements. These options are:

  • SCSI ID (Default setting = ID 5)
  • TERMPWR (Termination power, default = enabled)
  • Disable Wide SCSI (Jumper pins 1 and 2)

The following provides information on how to change these settings, refer to the drive diagrams provided to insure proper orientation.

To Set SCSI ID

Bare, Rack Mountable Drive

To change SCSI ID orient yourself to the drive as seen in figure 1-1 (face drive rear, power connector to left). The SCSI ID block has 10 pins arranged in two rows of 5, top row is odd numbered and the bottom row is even. Set the ID values according to chart 1-1 by placing a jumper across the appropriate set of pins. Please note that for this block setting to register with the drive a jumper must be in place across pins 9-10.

Tabletop Drive

Use the thumb wheel switch found at the back of the drive and set the number to the ID required.

To Set TERMPWR

Bare, Rack Mountable Drive

To change TERMPWR orient yourself to the drive as seen in figure 1-2 (face drive rear, power to your left). Please note that it is recommended that this jumper remain in place as all devices can provide TERMPWR. If required, to disable TERMPWR remove the jumper across pins 3-4. To enable TERMPWR place a jumper across pins 3-4.
