6) Two 68-pin Ultra160/320 SCSI Connectors (SCSI-A, SCSI-B)
This motherboard has two 68-Pin Ultra160/320 SCSI connectors; one for each
of the two channels. Each channel can support a maximum of 15 devices as
specified by Ultra160 standards.
SCSI Connection Notes
This motherboard has two 68-Pin Ultra160 SCSI connectors; one for each of the
two channels.
The onboard SCSI chipset incorporates an advanced multimode I/O cell that supports
both single-ended (SE), Ultra2, and Ultra160/320 devices. With Ultra160/320 devices,
the SCSI bus platform performs at full Ultra160/320 speeds (up to 160MB/sec or
320MB/s) and extended cabling 12m (or 25m in a point-to-point configuration).
When an SE device is attached, the bus defaults to an SE speed and 1.5m cable
length.
NOTE: Ultra160/320 SCSI devices do not have termination jumpers and
must use a separate terminator on the last connector (internal) or device
(external).

IMPORTANT: Connect SCSI devices as shown. Each channel should have
only one type of SCSI standard (e.g. Ultra160/320, Ultra2, Ultra-Wide). Mixing
SCSI devices on the same channel decreases performance of the slower device.
