5-2 SCSI Guidelines
!"
For workstations, if only one SCSI hard drive is used, it should be installed in the lowest
numbered bay (bay 1). (Refer to the product-specific MSG for application).
!"
All SCSI hard drives must be either internal or external, but never both. The system
accommodates a combination of other internal and external SCSI devices, such as tape and
CD-ROM drives.
!"
Turn on all external SCSI devices before turning on the power to the computer. This
enables the SCSI controller to recognize the external devices.
Using the Multi-Mode SCSI Cable
Some products ship standard with a three-device multi-mode SCSI cable having a terminator 1
on one end. This cable supports both low voltage differential (LVD) and single ended (SE)
devices. One end of the cable connects to the internal LVD/SE connector on the system board,
while the remaining three connectors being used on the hard drives in the hard drive bays. The
third device circuit must be used.

included with the device option kit.
