SCSI Bus Termination and Terminator Power

SCSI Bus Termination and 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).

Figure B-5

DLT4000 Tape Drive Connectors (right side)

Figure 14 and the table following it illustrate the possible 
position(s) for the TRM PWR/TRM ENB jumper(s).

If an external SCSI terminator is used, configurations 2 and 
4 in Figure B-6 on page B-6 cannot be used.

Note

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