Overview
Application Module hardware is based on Meridian 1 modular packaging.
The basic unit of the modular package is the Universal Equipment Module
(UEM), which is a modular, self-contained hardware cabinet that houses a
card cage with a power supply, backplane, circuit cards, and other basic
equipment. When the UEM is equipped, it generally supports a system
function and becomes a specific type of module, such as a CPU Module or
Intelligent Peripheral Equipment (IPE) Module.
The term "Meridian 1" is used throughout this document, and refers to
Meridian 1 and "Meridian 1-ready" systems (such as Meridian SL-1 style
cabinets that have been upgraded). See Applications Module overview
guide (553-3201-110) for further information on Application Module
requirements.
In addition, the UEM houses the card cage that supports the Application
Equipment Module (AEM). When this card cage is installed, the UEM
functionally becomes an AEM. There are two versions of the AEM:
NT7D18AA for ac-powered systems
NT7D18AB for dc-powered systems
Application Modules, such as the Meridian Link Module, are housed in the
AEM. Each AEM can accommodate up to two Application Modules. (If
only one Application Module is installed, a blank panel covers the rest of
the AEM to channel air flow for cooling.)
An AEM with a standard Meridian 1 pedestal and top cap can be
configured as a stand-alone column. In this configuration, the AEM can
interface with:
Meridian 1 system options 11, 21, 51, 61 or 71.
