6.0 SERVICE
MS-Series equipment has been designed using a subassembly concept. This
design feature allows for service by replacing a faulty assembly. The service
procedures described in this section will isolate a problem to the replaceable
assembly or component level as appropriate. Printed circuit board assemblies
are considered to be replacement items. Mainframe components such as
contactors, diode bridges, filter capacitors, etc. are considered replaceable
components.
