PIMs and BRIMs
This chapter deals with the special methods of connecting standalone and stackable devices to one
another regardless of cabling media or networking technology.
While many network design implementations are simple and straightforward,
there are several that must incorporate complexity beyond a single segment,
media type, or even a single networking technology. These complex networks are
quite frequently the domain of modular networking chassis, such as the
Cabletron Systems MMAC-FNB series of hubs, or the enterprise network switch
platform, such as the Cabletron Systems MMAC-Plus. It is important that
workgroup devices be able to support complexity, so Cabletron Systems has
designed support for different media, segmentation, and internetworking needs
into several of its workgroup solutions devices.
Port Interface Modules
In order to support a wider variety of networking needs, Cabletron Systems
incorporated specialized, user-configurable ports on many of its standalone and
stackable devices. These ports, called Port Interface Module slots, or PIM slots, are
available openings in devices into which a PIM can be placed. These PIMs can be
constructed to provide connectivity for any standardized networking technology
and most port types.
