Removal and Replacement Procedures

5

Overview

This chapter provides recommended procedures for the removal and replacement of MVME956AC chassis major assemblies. For identification and location of the assemblies and parts mentioned in these procedures, refer to the drawings and parts lists in Chapter 7.

The removal/replacement procedures are organized and presented in the following order:

❏Power Supply

❏Disk and Tape Drive

❏VME64x Bus Backplane

❏Cooling Fan(s)

❏Optional Air Filter Kit

Following ESD and Safety Procedures

Use ESD

Wrist Strap

Motorola strongly recommends that you use an antistatic wrist strap and a conductive foam pad when installing or upgrading the system. Electronic components, such as disk drives, computer boards, and memory modules, can be extremely sensitive to ESD. After removing the component from the system or its protective wrapper, place the component flat on a grounded, static-free surface, and in the case of a board, component-side up. Do not slide the component over any surface.

If an ESD station is not available, you can avoid damage resulting from ESD by wearing an antistatic wrist strap (available at electronics stores) that is attached to an unpainted metal part of the system chassis.
