3. HARDWARE SETUP SCSI Connection Notes This motherboard has two 68-Pin Ultra160/Ultra2 (depending on model) 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/Ultra2 devices, the SCSI bus platform performs at full Ultra160/Ultra2 speeds (up to 160MB/ sec or 80MB/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 will decrease performance to the slower device. 68-pin Internal SCSI Cable (Twisted-Pair Ribbon) Channel A R CUR-DLS Internal SCSI Devices (up to 15 devices) 68-pin Female Terminator 68-pin Internal SCSI Cable (Twisted-Pair Ribbon) Channel B Internal SCSI Devices (up to 15 devices) 68-pin Female Terminator CUR-DLS SCSI Connection Example NOTE: Ultra160/Ultra2 devices do not have termination jumpers and must use a separate terminator on the last connector (internal) or device (external). 3.

SCSI Connection Notes
This motherboard has two 68-Pin Ultra160/Ultra2 (depending on model) SCSI con-
nectors; one for each of the two channels.
The onboard SCSI chipset incorporates an advanced multimode I/O cell that sup-
ports both single-ended (SE), Ultra2, and Ultra160 devices. With Ultra160/Ultra2
devices, the SCSI bus platform performs at full Ultra160/Ultra2 speeds (up to 160MB/
sec or 80MB/sec) and extended cabling 12m (or 25m in a point-to-point configura-
tion). 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 will decrease performance to the slower device.
NOTE:
Ultra160/Ultra2 devices do not have termination jumpers and must use a
separate terminator on the last connector (internal) or device (external).
