Chapter 2

Safety Precautions

2.1 Introduction

This chapter discusses hazards and safety precautions that the Digital Services engineer

should be aware of before installing SA70–CK kit, SA70–LK/MK, SA71–NK/PK, SA72–

NK/PK, and SA73–NK/PK options into the VAX 6000-series processor cabinet.

Warning

Only qualiﬁed Digital Services engineers should perform these procedures. Digital

customers may access the SA70–LK/MK, SA71–NK/PK, SA72–NK/PK, or SA73-NK/PK

operator control panel only through the VAX 6000 OCP access panel on the front door.

Access to the options by opening the front or rear cabinet doors is prohibited.

2.2 Hazards and Safety Precautions

The front door of a VAX 6000-series processor cabinet is considered a safety barrier. High

voltages, as well as the blower assembly, are accessible once the front door is opened. The

cabinet door is locked and cannot be opened without a 5/32 hex key. Only Digital Services

engineers can open the front door without violating Digital safety measures.

SA7x enclosure line voltage switches come preset in the 220V/50Hz position as a safety

precaution. Ensure the line voltage switch is set to the proper position for the installation.

Refer to Chapter 3.

2.3 ESD Precautions

Only Digital Services engineers with training in electrostatic discharge (ESD) procedures

should install an SA7x enclosure or work with the processor cabinets.

Digital Services engineers must wear proper ESD protective ground straps connected to a

good ground when accessing, installing, or repairing SA7x enclosures or VAX 6000-series

processor cabinets. ESD kits, containing protective ground straps, are behind the front and

rear doors of the processor cabinets. Use this ground strap when working with the processor

cabinets. Use a separate ground strap connected to the SA7x enclosure when working with

the SA7x enclosure.
