SCSI Bus Termination and Terminator Power

Note

The SCSI bus must be terminated at both ends, and at least one device must supply terminator power.

The following paragraphs describe information about termination selection on different drives.

DLT4000 Drives

The DLT4000 drives can be configured to supply terminator power and termination on the bus, by jumpering specific pins on the TRM PWR/TRM ENB connector. See Figure B-5 for the location of the TRM PWR/TRM ENB connector).
