6)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.

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.
