2.4 Terminating the SCSI Bus
The SCSI bus contains all the devices that you connect with SCSI cables. When you connect the first and last physical SCSI devices on the ends of the SCSI bus, you must have termination active. You must remove or disable termination on all other SCSI devices on the same bus.
If you connect only internal SCSI devices on a bus, the host adapter automatically terminates itself. If you connect only external SCSI devices on a bus, the host adapter also terminates automatically. Automatic termination occurs because the host adapter connection is at the end of the SCSI bus. If you connect both internal and external SCSI devices on a bus, the host adapter automatically disables its termination. This occurs because the host adapter is in the middle of the SCSI bus. Termination for host adapters with only one connector per channel is always enabled for the channel.
