Refer to the operating system drive configuration supplement for information on scripts and • other settings for various non-Windows operating systems. This supplement is available on your Tape Resource CD and at http://support.certance.com. Table 4 shows the supported operating systems and their corresponding switch settings. TABLE 4. -
Page 25: Scsi Wide/Narrow Configuration (Dds-4 Drives Only)
Switch 9 enables SCSI Wide or Narrow operation. By default, switch 9 is set to ON, enabling SCSI Wide (16-bit) operation. To enable SCSI Narrow (8-bit) operation, set switch 9 to the OFF position. This allows the DDS-4 drive to terminate the upper byte of the SCSI bus. NOTE: Narrow SCSI is not recommended. -

Installing internal tape drives Mounting the Internal Tape Drive Mounting the Drive into a 5.25-inch Drive Bay The following procedure describes how to mount the drive in a 5.25-inch drive bay. This procedure assumes your drive has mounting brackets on the sides. Orient the drive so the front of the drive faces the front of the computer. -
Page 29: Connecting A Scsi Cable
Installing internal tape drives Connecting a SCSI Cable Connecting a SCSI Cable The internal tape drives can be used with two SCSI interfaces: • Wide SCSI — either Low Voltage Differential (LVD) or Single-ended (16-bit Wide mode), • Narrow SCSI — either Low Voltage Differential (LVD) or Single-ended (8-bit Wide mode). The tape drive automatically detects whether the SCSI bus is LVD or single ended. -

Data with little redundancy, such as executable programs, are compressed the least. • Media Recognition System (DDS-4 Drives Only) Using non-DDS media may appear to give satisfactory results, but the inferior specifications of such media can cause data-integrity problems. To avoid these problems, the external tape drive provides a media-recognition system (MRS) feature that determines whether tape cartridges conform to the DDS tape standard. -
Page 37: Connecting A Scsi Cable
Installing external tape drives Connecting a SCSI Cable Connecting a SCSI Cable The external tape drives provide two 68-pin, shielded connectors on the back panel (see Figure 11 on page 35). You can use either connector to attach the drive to the host computer or to another SCSI device. -
Page 38: Checking Scsi Termination
Installing external tape drives Checking SCSI Termination NOTE: Be sure the upper 8 data bytes of the 68-pin cable are properly terminated. Checking SCSI Termination If the external tape drive is the last or only device in the SCSI chain, install a terminating plug on the unused SCSI connector on the drive’s back panel. -
