4) Two 68-pin Ultra160/Ultra3 SCSI Connectors

This motherboard has two 68-Pin Ultra160/Ultra3 SCSI connectors, one for each

of the two channels. Each channel can support a maximum of 15 devices as

specified by Ultra160/Ultra3 standards.

SCSI Connection Notes

The onboard SCSI chipset incorporates an advanced multimode I/O cell that supports

both single-ended (SE), Ultra3, and Ultra160 devices. With Ultra160/Ultra3 devices,

the SCSI bus platform performs at full Ultra160/Ultra3 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, Ultra3, Ultra-Wide). Mixing SCSI devices

on the same channel decreases performance of the slower device.

NOTE: Ultra160/Ultra3 SCSI devices do not have termination jumpers and must

use a separate terminator on the last connector (internal) or device (external).
