Dead Unit Procedure
A dead unit is one which does not appear to function at all.
Power Supply
The power supply consists of an ac power receptacle and voltage select switch, a switching ac-to-dc
converter, post-regulators and a dc-powered cooling fan. The converter is contained on the power
supply board. The post-regulators are mounted on the
liD
connectorboard. The fan is mounted on
the rear panel. The power receptacle and voltage select switch protrudes through the rear panel,
but is actually mounted on the chassis. The assemblies and components included in the power
supply are pointed out in Figure 8-2.
