2.6.3 Connecting Ultra/Fast Narrow SCSI Devices
If you have internal Ultra/Fast Narrow SCSI devices with standard 50-pin connectors,
you can connect them to the 50-pin internal SE Narrow SCSI connector. Follow
these steps to connect the devices:
1. Locate the provided 50-pin internal Ultra/Fast Narrow SCSI cable.
2. Connect one end of the cable to the 50-pin internal SE Narrow SCSI connector.

3. Connect the other end of the cable to a terminated Ultra/Fast Narrow SCSI device.
Pin-1 must match on all connections.
4. If you have other Ultra/Fast Narrow SCSI devices, attach them to the connectors
between the two ends of the cable. Be sure these other devices are unterminated.
5. Connect a power cable from your computer’s internal power supply to each
internal SCSI device.
2.6.4 Connecting External SCSI Devices
You can connect external Ultra160 and Ultra2 SCSI devices to the 68-pin external
LVD/SE SCSI connector. The external devices will require a 68-pin VHDCI external
LVD SCSI cable.
NOTE: We recommend that you connect only Ultra160 and Ultra2
SCSI devices to the external SCSI connectors in order to achieve the
maximum data transfer rate.
