Chapter 4 – Power Distribution

0818D User’s Guide

4-1

Unless working on hot-swap components, always shut
down the system and turn OFF all power and disconnect
the power cord before working on the system

4 Power

Distribution

This chapter

discusses the input power modules, power supply and

input circuit breaker, and provides installation and removal
instructions for each.

CAUTION!

4.1 Dual Input Power Modules

The reliability of the 0818D system is enhanced by being powered by
two independent DC power sources. The utilization of these two
power sources is controlled by two input power modules, each fed by
a different and separate source of power. No interconnection wiring
between the two modules is needed. See Figure 4-1.
