EK–BA42A–AD. A01
January 1993
Dear BA42 Expansion Box Customer:
This document describes how to install the RZ26 hard disk drive in your BA42
storage expansion box and provides the RZ26 drive hardware specifications.
The RZ26 drive installation differs from the hard disk drive installation
described in the BA42 Storage Expansion Box Installation Guide because of a
new internal SCSI ID switch cable adapter.
Insert this document into your BA42 Storage Expansion Box Installation Guide
(in the hard disk drive section of Chapter 2) for future reference.
