9. 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/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.
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.
