are connected serially (chained together) with SCSI cables. The first and last physical devices connected on the ends of the SCSI bus must have these terminators enabled. All other SCSI devices on the bus must have their terminators removed or disabled.
Termination on the LSI20860 is automatically enabled when it is connected to the end of the bus. Refer to the SCSI device documentation for information on how to identify and change the terminator setting on each SCSI peripheral device.
