U
npack the tape drive (and controller card, if applicable) and configure the tape drive according to
the documentation that came with the tape drive, based on the following guidelines:
a
Each device attached to a SCSI host adapter must have a unique SCSI ID number. (Narrow SCSI
devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15). Set the drive’s SCSI ID to avoid
conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the
documentation provided with the drive.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to
the cable in order by ID number.
b
SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that
all devices in between be unterminated. Therefore, you enable the tape drive’s termination if it is
the last device in a chain of devices (or sole device) connected to the SCSI controller.
8 If a controller card was included in the drive kit, install the card now. See
"Installing an Expansion
Card" on page 57
