The rugged 19”/2 design addresses the modern requirements for small, high performance IT infrastructure components. The modular design and broad product range enables the user to use the different 19”/2 units as building blocks to design optimal system for every use case. The ability to readily combine communication units of the 19” form factor with units of 19”/2 form factor gives the practical benefits of integrated solutions and endless configuration possibilities to quickly build the communication system you want. A key consideration taken into account by the 19”/2 form factor was to make it sustainable. This satisfies the demand of defence equipment purchasers for the long-term stable supply of particular types of equipment. Such sustainability also matches the long lifecycles of most military vehicles and aircraft, and the need to continually update systems.
