Checking the SCSI Termination

Figure 6 Two SCSI Termination Examples for the Internal LTO-2 Half-Height Tape Drive

By default, the internal LTO-2 Half-Height Tape Drive does not provide SCSI termination. If you use this default setting, you must place a SCSI bus terminator or a SCSI device with termination enabled at the end of the SCSI chain. See figure 6 for two examples of SCSI termination.

The internal LTO-2 Half-Height Tape Drive provides terminator power if a jumper is placed on the termination power jumper pins (see Terminator Power on page 10).
