Installing the RZ26 Hard Disk Drive in the BA42 Expansion Box

This document provides instructions for installing the RZ26 hard disk drive into a BA42 storage expansion box. It highlights a key difference from previous installations: the use of a new internal SCSI ID switch cable adapter specific to the RZ26.

The installation process covers:

1. Preparation: Checking the shipment contents (RZ26 drive, documentation, SCSI ID adapter cable) and verifying the current system configuration to identify available SCSI ID numbers.
2. SCSI ID Setup: Detailed steps for setting the SCSI ID switches on the BA42 expansion box, including removing the switch cover and using a provided table of switch settings for different SCSI ID numbers.
3. Physical Installation: A step-by-step guide for mounting the drive, which involves:
   • Removing the BA42 box cover.
   • Attaching the SCSI ID adapter cable to the RZ26 drive (ensuring proper pin alignment and removing any conflicting jumpers).
   • Connecting the adapter cable to the appropriate SCSI ID cable connector inside the BA42 (noting differences between RZ5x and RZ2x cable types).
   • Attaching the main SCSI signal and power cables to the RZ26 drive.
   • Inserting the drive into the expansion box and securing it with a captive screw.
   • Replacing the BA42 box cover, ensuring internal cables are clear.
4. Verification: Instructions on how to confirm a successful installation using the system's SHOW CONFIG command and troubleshooting steps if the drive is not recognized (e.g., checking power, cable connections, SCSI terminator, damaged pins, and SCSI ID settings).

Finally, the document includes a section detailing the RZ26 hard disk drive's hardware specifications, such as weight, dimensions, formatted storage capacity (1050 MB), performance metrics (e.g., 2.6 MB/sec data transfer rate, 10 msec average seek time), and operating/non-operating environmental conditions.
