Chapter 1- Hardware Description

AC Power Entry Module (PEM)

An AC PEM includes a power inlet, EMI filter and backplane connectors. Power input to the system is fed via a PEM (Power Entry Module) through backplane into the power supply. Each AC power module has its own dedicated power cable. The ON/OFF switch on the rear of the RMX activates any power module installed on the RMX. An AC system has three AC PEMs, one for each power module. On failure, both AC power supplies and PEMs are hot swappable.

DC Power Rail Module

A DC power rail module includes a power inlet, circuit breaker, EMI filter and backplane connectors. Power input to the system is fed via a power rail through backplane into the power supply. Each DC power rail has its own dedicated power cable. The circuit switch on the rear of the RMX activates independently any power rail installed on the RMX. An DC system has two DC rails, one for each power rail. On failure, a DC power rail is field replaceable and the RMX must be switched OFF from the two circuit switches and the mains.
