4.2.4Connecting the 50-Pin SCSI Interface Cable
The product installation kit includes a new 50-pin SCSI interface cable
(DWB-10193-04). However, if you are currently using SCSI devices, your old 50-pin
cable plugged into the SASI port on your main CPU board may work just fine. If you find
that your existing cable is long enough to allow it to be plugged into the SCSI port on the
Roadrunner board, you can use your old cable. If you use the SCSI cable included in
the product kit, it should be installed and routed as shown in the illustration below. All
cable connections must be made pin-1 to pin-1.
Your product installation kit also includes an external terminator. This terminator plugs
into the external SCSI connector on the rear panel of your computer. If you use the
external terminator, you must insure that none of your internally mounted SCSI devices
have terminators installed.

When an external SCSI terminator is used, any SCSI device
with internal SCSI termination must have its terminators removed!
Also, the AM-174 is factory set to supply termination power to
the SCSI bus. When the AM-174 is used in its factory default
configuration, all other SCSI devices must have their SCSI bus
termination power disabled (if applicable).
