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.
