Figure 4. External SCSI cable (optional)
Color Strip
The External SCSI cable is a fifty-pin flat ribbon cable with two internal connectors and
one external SCSI-2 port.
External devices should be connected to the external port with a SCSI-2 cable. If there
are more than one internal or external devices, they should be daisy-chained to the
external port connector. On the whole, the end device (the last one away from the host
connector on the motherboard) must be terminated, or the devices in the chain will not
work properly.
The following diagram shows how the external SCSI cable should be connected for
internal and/or external SCSI devices.
If there is NO external SCSI device attached, such as Device 1 and Device 2, then a
active terminator is required to be in place at the external port connector.
SCSI ID Number
All SCSI device, including this board have a SCSI identification number that is not in
used by any other SCSI device. There are eight possible ID numbers, 0 through 7. The
Yukon HX has a fixed SCSI ID of 7.
You can connect up to seven SCSI devices to the board. You must set a SCSI ID
number for each device. Different SCSI devices vary in the way they set the ID number.
Some use jumpers, others have some kind of selector switch. Refer to the manual of
each particular SCSI device that you installed on the board for instruction on how to set
its ID number.
