Chapter 2 SDLT 600 Tape Drive Specifications
Product Specifications
The tape drive automatically senses the SCSI bus mode and switches
between LVD and SE accordingly. Although the tape drive defaults to
LVD, it switches to SE if the SCSI bus operates in SE mode. For example,
if the SCSI controller card is SE (or multimode set to SE), the tape drive
automatically switches to SE mode. Also, if any device on the SCSI bus is
SE, the entire bus switches to SE, including the tape drive.
In SE mode, the SCSI bus can support up to 7 devices using cable lengths
up to 3 meters. In LVD mode, the SCSI bus can support up to 15 devices
using cable lengths up to 25 meters.
