Application Module
An Application Module (AM) is a Versa Module Eurocard (VME) platform
that is packaged with the Application Equipment Module (AEM) of a
Meridian 1. The AEM is a modified Universal Equipment Module (UEM),
and can house two separate Application Modules.
The Application Module consists of a VME bus backplane, a single board
computer (SBC) card, one or more I/O cards and corresponding transition
cards, a hard disk and streamer cassette tape unit, and a power supply. The
Application Module chassis measures approximately 35.5 cm (14 in.) high,
32 cm (12-3/4 in.) wide and 32 cm (12-1/2 in.) deep.
An Application Module can co-reside with another Application Module in a
single Application Equipment Module.
If your Application Module contains Meridian Link but not CCR, it is
referred to as a Meridian Link Module and may have one of the five
configurations shown in Table 8. Table 8 shows the upgrade path for each
configuration. Notice that the second and fourth configurations are the first
and third configurations upgraded to an MVME167 card.
If your Application Module contains CCR but not Meridian Link, it is
referred to as a CCR Module and may have one of the five configurations
shown in Table 9. Table 9 shows the upgrade path for each configuration.
Notice that the second and fourth configurations are the first and third
configurations upgraded to an MVME167 card.
Your current module may have other hardware that varies from other
modules (for example, I/O panels, tapes, and disk drives), but these are not
important for determining upgrade paths.
The Application Module allows PC-based Meridian Link and CCR
maintenance consoles, CCR scripting consoles, and LAN-based host
computers to be connected to the Application Module through Ethernet.
