For convenience, Channel A also has a 50-pin narrow (ribbon) connector. Some internal cables come with an SE/LVD terminator on one end. This end should be furthest from the host adapter.

All external SCSI bus connections to the LSI21003 are made with a shielded, 50-pin high density cable (see Figure 2.3). The connectors on this cable are always keyed to ensure a proper pin-1 connection.
