RZ-Series 3 1/2-Inch Fixed Disk Drive Installation

This document is an installation guide, published by Digital Equipment Corporation in September 1993, for their RZ-Series 3 1/2-inch fixed disk drives.

It provides:

• Specifications for the RZ26 (1.0 GB) and RZ28 (2.1 GB) models, including capacity, form factor, seek time, transfer rate, rotational speed, temperature, humidity, voltage, current, and power consumption.

• Installation instructions and diagrams, highlighting critical steps such as:

  • A caution to remove SCSI resistor packs and terminator jumpers when adding a drive to a DEC 4000 AXP system to prevent bus issues.
  • Illustrations of the RZ-Series 3 1/2-inch SCSI and Fast SCSI storage assemblies, showing cable connections, SCSI ID module placement, and drive removal.
  • Information on Bus Node ID selection for drives within a storage tray.
  • Identification of various components on the drive's bottom, including the SCSI connector, power connector, resistor packs, SCSI ID, busy/fault lights, and the spin-up jumper.

• An explanation of the spin-up jumper's function, determining if the drive spins up on power-up or upon a MOUNT command.
