1.0INTRODUCTION
This document describes the installation of both 3-1/2" and 5-1/4" SCSI disk drives into
an Alpha Micro computer. It is written for the experienced Alpha Micro Service
Technician, so if you do not feel comfortable performing the hardware and software
procedures discussed in this document, please contact your Alpha Micro Dealer or the
Alpha Micro Technical Support Group for help.
Installing a SCSI disk drive is simply a matter of placing the drive inside your computer
chassis, connecting the appropriate power and interface cables, and configuring the
correct software. Those wishing to install a SCSI drive into an external subsystem
should refer to the installation instructions for the
AM-1601 Subsystem, PDI-01601-00,
or the
SCSI Universal Subsystem , PGI-00001-00.
This document contains information for each SCSI disk drive currently sold and
supported by Alpha Micro. This information includes drive addressing, terminator
locations, and other items unique to the various drive manufacturers.
