Generically, systems that do not use the NT8D37 IPE shelf derived from products that used a main cabinet (with the CPU) and added more cabinets as expansion cabinets to provide larger systems. Eventually, rack-mountable variants referred to as main or expansion chassis were created. Although, the main versus expansion description for the cabinet is sometimes functional. The same cabinet hardware can be a main cabinet or expansion cabinet based on its use. However, the chassis serves as a main cabinet, and the chassis expander as an expansion cabinet equivalent.

A majority of IPE line cards and hardware from the chassis and cabinets can be reused. For example, there is no specific version of the NT5K02 Flexible Analog Line Card that is supported. All are supported. If a specific version is indicated, this indicates incompatibility of lower versions with CS 1000, as opposed to with Device Adapter.

Any problem in a specific vintage card that may be fixed in a higher version of the card will remain on the card after migrating to Device Adapter. This applies to the IPE shelf. However, most customers upgrade the hardware to versions that meet their needs. The cards may not have been upgraded to get additional feature content, though.

The systems use a number of cabinets and chassis. However, the following are explicitly not supported:

These do not support the MGC and must be replaced by an NTAK11 cabinet if you want to retain the users’ stations.

The following chassis and cabinet equivalents, including chassis expanders as applicable, to an NT8D37 IPE shelf are supported:

Trunk cards, including music and recorded announcement, and conference resources are not migrated to Device Adapter. However, the following line cards can migrate:

The following hardware and cards are also reused:
