DSP2022-S SCSI Disk Drive Installation Guide

This document is the Installation Guide for the Digital Equipment Corporation DSP2022-S 2.5-inch SCSI Disk Drive.

It provides detailed information and instructions necessary to configure and install the drive, covering the following key areas:

• Pre-Installation Cautions: Emphasizes the importance of antistatic precautions and careful handling of the delicate drive.
• SCSI Connector and Pin Functions: Details the 50-pin SCSI connector, explaining both the standard SCSI interface signals and vendor-specific pins (A1-A8) used for functions like remote SCSI ID setting and external activity LED power.
• Jumper Configuration: Describes the J1 jumper connector and its functions. This includes how to set the SCSI device address (using jumpers 0, 1, and 2), enable or disable automatic spin-up and set a spin-up delay, and provide power for an external SCSI bus terminator (via jumper 7). It also covers remote SCSI address determination.
• Mounting Guidelines: Specifies that mounting kits are not included. It illustrates the locations of side and bottom mounting holes and provides critical guidelines for mounting, such as permissible orientations, the required M3 x 0.5 metric screw type, and maximum screw penetration depths to avoid damage.
• Drive Specifications: Concludes with a summary of the drive's performance (e.g., 220 MB formatted storage, 5400 RPM, average seek time) and environmental characteristics (dimensions, weight, power consumption, operating temperature, and altitude).
