Connecting Cables

1. When you connect a SCSI cable to this card, you must align the cable so that
the Pin 1 side of the cable connector is at the Pin 1 side of the cable connector
on the card. The two SCSI connectors use different cables. The Fast SCSI
connector connects to a 50-pin flat ribbon cable. The Pin 1 side of the ribbon
cable is marked with a colored edge and the Pin 1 side of the connector on the
card is labelled on the card. The Wide SCSI connector connects to a cable that
has a connector which can only be attached to the card in one orientation,
making the Pin 1 matchup automatic.
2. After you connect the cables to the host adapter, review the subject of SCSI
identification (ID) numbers and termination covered in Section 4. Make sure
that all devices you connect to the SCSI adapter have different ID numbers and
that only the SCSI adapter and the last SCSI device on each bus is terminated.
3. Connect a cable between the host SCSI adapter and an internal SCSI device
installed in your system. If there is more than one device, connect the addi-
tional devices with additional cables. You can connect up to seven devices to
the Fast SCSI bus and fifteen devices to the Wide SCSI bus.
