Page 5: Scope Of Information
DSP2022-S SCSI Disk Drive Installation Guide 1 Scope of Information This guide supplies information needed to configure and install your Model DSP2022-S 2.5-inch Small Computer System Interface (SCSI) disk drive. The tasks you need to perform are listed in order in the table of contents. The specifications for the disk drive are found on the last page. -
Page 6: Locate The Scsi Connector
2 DSP2022-S SCSI Disk Drive Installation Guide Locate the SCSI Connector Locate the SCSI 50-pin connector shown at the rear of the drive in Figure 1 . This connector is used for cable installation later. Note that the pins of the SCSI connector are divided into two pin fields: one for the SCSI interface... -
Page 7: Note Pin Status Of The Vendor-Specific Field
DSP2022-S SCSI Disk Drive Installation Guide 3 Note Pin Status of the Vendor-Specific Field The vendor-specific pin field consists of pins A1–A8. These pins are used for testing at the factory, setting the SCSI ID address remotely, and supply power to an external drive activity light emitting diode (LED). -

Page 9: Locate Jumper Connector J1
DSP2022-S SCSI Disk Drive Installation Guide 5 Locate Jumper Connector J1 Locate jumper connector J1 on the electronic component side of the drive, shown in Figure 2. Note that connector J1 contains eight jumper pairs numbered 0 through 7. Your drive comes with all jumpers in place. -
Page 10: Learn The Jumper Functions
6 DSP2022-S SCSI Disk Drive Installation Guide Learn the Jumper Functions The jumper functions on the SCSI drive are described in Table 3. These jumpers allow you to set the device address, disable automatic spin-up, change the delay time before spin-up, and enable drive power for an external SCSI terminating resistor. -
Page 11: Set The Scsi Device Address
DSP2022-S SCSI Disk Drive Installation Guide 7 Set the SCSI Device Address Jumpers 0, 1, and 2 are used to set the SCSI device address. Table 4 shows the jumper IN or OUT status for setting the SCSI device address. IN means jumpers are in place and OUT means jumper are removed. -
Page 12: Set The Scsi Address Remotely
8 DSP2022-S SCSI Disk Drive Installation Guide Set the SCSI Address Remotely When jumpers 0, 1, and 2 are left in place for a device address of 0, the drive will use the remote active encoded SCSI device address (ID) number on the vendor-specific connector at the rear of the drive. -
Page 13: Provide Scsi Bus Termination
DSP2022-S SCSI Disk Drive Installation Guide 9 Provide SCSI Bus Termination The SCSI bus only needs termination resistors at the beginning and end of the bus. Since this drive does not have a SCSI bus terminating resistor on it, bus terminating resistors must be located external to the drive. -
