Adding External SCSI Drives
You can add single-ended external SCSI drives to the system by connecting them to the SCSI port on
the back of the base unit. Additional SCSI option boards (adapters) can be installed to support
external SCSI drives as well. The section “Adding Option Boards” earlier in this chapter describes
installing new boards.
The Adaptec AIC-7860 SCSI controller (on MSMT353, MSMT359 and MSMT378 system boards)
provides the Ultra SCSI bus for external devices.
