Connecting SCSI Devices 1-11
are connected serially (chained together) with SCSI cables. The first and
last physical devices connected on the ends of the SCSI busmust have
these terminators enabled. All other SCSI devices on the bus must have
their terminators removed or disabled.
Termination on the LSI20860 is automatically enabledwhen 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.
