Digital Storage Products Disk Drive (Models DSP5200 & DSP5350)

This document is an Installation Guide from Digital Equipment Corporation, published in May 1993, for their Digital Storage Products: the Model DSP5200 (2000 MB, SCSI-2 Single-Ended/Differential) and Model DSP5350 (3570 MB, SCSI-2 Single-Ended) disk drives.

The guide provides detailed instructions and specifications for:

• Introduction & Handling: An overview of the drives and a caution on observing antistatic precautions during handling.
• SCSI Configuration: How to set the SCSI address, configure spin-up behavior, enable LED indicators (Busy/Fault), and implement remote control options using jumpers on the option connector. For the DSP5350, it also describes spindle synchronization.
• SCSI Bus Termination: Explains the termination requirements for both models, including jumper settings for termination power. It notes that the DSP5200 uses removable resistor packs while the DSP5350 features built-in active termination, both only required at the end of the SCSI bus.
• Power Connections: Specifies the +5VDC and +12VDC power requirements via a 4-pin connector and provides detailed electrical specifications like voltage regulation, ripple, current consumption (spin-up, idle, seeks), and total power.
• Mounting: Guidelines for physical installation, including allowable orientations, clearance requirements, and proper screw specifications, with a warning against using screws that are too long.
• Summary of Specifications: Comprehensive technical data including SCSI 50-pin connector pin assignments, disk drive functional specifications (e.g., formatted capacity, seek time, transfer rates, RPM), and environmental conditions (operating and non-operating temperature, humidity, and altitude).
