Compatibility
The Avaya Definity 63343 16 MB Memory Card is intended for use with compatible Definity Release 9 or greater systems. Because Avaya Definity installations can contain different hardware and software configurations, verify the existing memory card, system release, and part number before ordering a replacement.
For organizations that continue to operate Avaya Definity communications equipment, maintaining compatible replacement components can help extend the useful service life of the installed telephone system. A spare 63343 memory card can also be useful for technicians responsible for maintaining legacy Definity equipment and minimizing downtime when replacement components are required.
The 16 MB capacity and specific Definity Release requirement are important considerations when selecting this memory card. Confirming that the system is running Definity Release 9 or greater before installation helps ensure that the card is being used in the application for which it was designed.
