Two 68-pin Ultra160 SCSI Connectors (CHA-WIDE, CHB-WIDE)
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.
NOTE:
Ultra160 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, Ultra2, Ultra-Wide). Mixing SCSI
devices on the same channel decreases performance of the slower device.
