These are the three core building blocks. Network zone systems are basically sealed enclosures that are utilized for din mountable industrial switches. This zone allows all cables within a cell/area zone to be managed and patched within a single enclosure. The second building block is Industrial distribution frame that is engineered to deploy and protect 19 inch rack mount switches both physically and thermally in harsh industrial environments. These can be copper based or fiber based switches. The third and final industrial block is the Micro Data Center, this is not a sealed enclosure and is designed for enterprise floor. It allows system integrators to reliably deploy rack mount equipment while protecting the critical physical media that makes up the industrial network. The MDC is supplied in an assembled form, ready to accept the servers, switches and storage devices.  More details on all these pre-configured building blocks are found in different Product Training Modules on the DigiKey website.
