As described previously, the VMA1832 or CVM03050-0 does not support identifying itself to an N2 supervisor as a VMA device type. As a result, you must reconfigure the N2 supervisor so that it is mapped as a VND device. Also, if the VMA1832 or CVM03050-0 N2 point mapping does not exactly match its N2 supervisor's point mapping, then you need to reconfigure the N2 supervisor so that it does. The procedure for performing these changes depends on the type of N2 supervisor.

  • For an N30 type N2 supervisor, perform these changes offline using the Project Builder tool. Refer to the Project Builder User's Guide (LIT-693205).
  • For an NAE type N2 supervisor, perform these changes offline using the System Configuration Tool (SCT). Refer to N2 Integration with the NAE Technical Bulletin (LIT-1201683).
  • For an NCM type N2 supervisor, changing the NCM database requires you to delete the old hardware and define the new hardware. The incremental DDL compile method (@NC+) using the DELETE keyword simplifies the NCM database change. GPL and JC Basic processes may not need to be recompiled. Refer to the DDL Programmer's Manual (LIT-630010).
  • For an SNE or SNC type N2 supervisor, perform these changes offline using the SCT.

For replacements that switch to VND Device Type, there are point mapping restrictions depending on the type of N2 capable equipment controller that is used to replace the N2 device. The following tables define the point limits of the new devices. To determine the appropriate point limits, use the tables of the devices which you are defining them as. In all cases, use the lower of the point limits of the N2 equipment controller and of the device it is defined as.

To make the VMA1832 replacement operation as similar as possible to the old VMA14xx device:

  • Select a Supervisor Object Type that matches the replaced controller point.
  • For multi-state objects, select an appropriate States Text table.
  • Use the Supervisor Object Definition to restrict commands.
