Figure 26 SCSI termination on a single Ultrium tape drive
If you have more than one device on the SCSI bus, daisy-chain them by connecting an LVD-rated cable
from the SCSI-OUT connector on the first device to the SCSI-IN connector on the second device. Assuming
you have two Ultrium tape drives connected, the enclosure on the second drive provides termination.
The green ACT Term LED on the rear of the first drive will be off while on the rear of the second drive it
will be on. If the second device is not an Ultrium external drive, make sure that it is terminated using an
LVD-rated multimode terminator.
