peripherals.

end of the Ultra2 internal SCSI cable.
important!
Connecting Internal Cables for Non-Ultra2 SCSI Devices
Internal cables for single-ended SCSI devices do not have special twists or
terminators built into the cable ends. If you are connecting non-Ultra2 SCSI
devices, use a channel separate from the Ultra2 SCSI devices you just con-
nected. The motherboard has a special 50-pin narrow connector to more easily
support narrow Ultra and earlier devices if you so choose.
If you are connecting Wide SCSI peripherals you will need a 68-pin cable. If
you are connecting narrow SCSI peripherals you will need a 50-pin cable.
When connecting the 50-pin cable to peripherals ensure that the colored edge
of the cable connects to pin 1 of both the device and the motherboard SCSI
connector.
STEP 1: Locate a 68-pin or 50-pin internal Ultra SCSI cable.
