6) Two 68-pin Ultra160 SCSI Connectors (SCSI-A, SCSI-B)
This motherboard has two 68-Pin Ultra160 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 devices. With Ultra160 devices, the
SCSI bus platform performs at full Ultra160 speeds (up to 160MB/sec) 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.
IMPORTANT: Connect SCSI devices as shown. Each channel should have only
one type of SCSI standard (e.g. Ultra160, Ultra2, Ultra-Wide). Mixing SCSI devices
on the same channel decreases performance of the slower device.
NOTE: Ultra160 SCSI devices do not have termination jumpers and must
use a separate terminator on the last connector (internal) or device (external).
