Connecting to the SCSI Bus
You are now ready to connect the adapter to the SCSI bus.
!
Caution
Single-ended and differential SCSI devices are
electronically incompatible and cannot be mixed on the
same physical bus. Mixing single-ended and differential
SCSI devices on the same bus can cause permanent
damage to both the peripherals and the PCI adapter.
!
Caution
Cables of different impedance should not be mixed on
the same physical bus.
