SCSI Ports and Connections

SmallComputerSystemsInterface
Information
This appendix describes the Small Computer Systems Interface (SCSI). Topics
covered in this appendix include:
•
SCSI ports and connections
•
SCSI bus length
•
SCSI bus termination information
If fast SCSI devices and old-style connectors must be used in the same system,
the old-style connectors should be connected to a separate SCSI port that
doesn't contain fast SCSI devices. Do not connect fast SCSI devices and old-
style connectors in the same daisy chain.
Old-style connectors can be identified by:
•
3-row 50-pin D connector
•
50-pin ribbon style connector
•
50-pin "Centronics style" of a connector (1/2-inch Front Load Tape (FCT)
drive)
There are four microminiature SCSI ports on the back panel of a tape library.
The SCSI connectors have 50 pins divided into two rows. You can connect the
tape library to your system in two ways—direct connection or a daisy chain.
