Cables and Connectors (SCSI Models)

Which SCSI
Connectors to Use

Models with a SCSI card can be connected to up to three internal SCSI
devices.

Additional devices can be added outside the PC by connecting directly to
the rear panel SCSI connector. The SCSI card allows up to 15 devices to be
connected, three internal and 12 external SCSI devices.

NOTE

The total length of the external SCSI cables should not exceed 3 meters
(approximately 10 feet).

Before Installing a
SCSI Hard Disk
(Selected Models
Only)

If you are installing an additional SCSI drive, you should configure an
unused SCSI ID to this accessory.
SCSI IDs range from 0 to 15 for
Ultrawide 16-bit SCSI. SCSI ID 0 is used by the first SCSI hard disk drive
and SCSI ID 7 is reserved for the integrated SCSI controller (the default for
narrow and wide SCSI devices).

You should assign an unused SCSI ID to the second SCSI hard disk drive
(for example, SCSI ID 1).
