SCSI Cabling and Configuration
When mixing 8-bit and 16-bit SCSI devices on the same physical SCSI bus, follow
these cabling and configuration guidelines to insure proper device addressing and
operation:
If all external mass storage devices use 68-pin connectors, connect all non-Sun
devices to the Ultra 2 Series system first and follow them with Sun devices. Sun
devices use autotermination.
If external mass storage devices consist of 68-pin Sun devices and 50-pin devices,
connect the Sun 68-pin devices to the Ultra 2 Series system first and terminate the
daisy chain with the 50-pin device and its terminator.
See the following figure for a summary of cabling and configuration guidelines.
