This command can be used to shutdown operation of IP500v2 memory cards. This action or a system shutdown must be performed before a memory card is removed from the unit. Removing a memory card while the system is running may cause file corruption.

For IP500v2 systems, shutting down the memory card will disable all services provided by the card including Embedded Voicemail. For IP500v2 systems, features licensed by the memory card will continue to operate for up to 2 hours.

Card services can be restarted by either reinserting the card or using the Start Up command.
