Installing a Desktop LTO-2 Half-Height Tape Drive

The desktop LTO-2 Half-Height Tape Drive is a compact subsystem that connects to the host computer through a SCSI port. Installing a desktop drive involves the following steps:

1Setting the SCSI ID

2Connecting a SCSI Cable

3Checking the SCSI Termination

4Connecting a Power Cord

5Registering Your Tape Drive

Setting the SCSI ID Each SCSI device on the bus must have its own unique SCSI ID. The desktop tape drive is shipped with a default SCSI ID of 6. Avoid setting drive ID to 7. If another SCSI device in the SCSI chain is already using this ID, either use the push-button switch on the back of the drive to change the drive’s SCSI ID or assign a unique SCSI ID to the other SCSI device.

If you change the SCSI ID on the tape drive, turn off the tape drive before changing the SCSI ID. The change takes effect when you turn on the drive.

Note: The SCSI controller or host adapter generally uses ID 7. In some systems, the boot drive uses ID 0 or ID 1. Avoid setting your drive’s SCSI ID to these settings.

Connecting a SCSI The desktop LTO-2 Half-Height Tape Drive has two 68-pin, shielded

CableSCSI interface connectors (ANSI Alternative 2) on the rear panel. These connectors consist of two rows of ribbon contacts spaced 2.16 mm (0.085 in) apart. Either connector can be used as a SCSI IN or SCSI OUT connection. This means you can use either connector to attach the drive to a host computer or to another SCSI device.

1Turn off all power to the drive and the computer.

2Attach the SCSI interface cable to one of the 68-pin SCSI interface connectors on the back of the drive.
