A modular, scalable and expandable rack-based information handling system includes: a rack assembly having a frame that defines: a front bay chassis with height, depth and width dimensions that enable insertion of a plurality of different sizes of IT gear; and a rear bay that accommodates power and cooling components to support operation of the different sizes of IT gear. Each user has an associated address-table which stores user defined labels associated with network addresses. The data processor processes an input digital signal to output at least one of first and second digital signals which are related to a higher bit portion and a lower bit portion of the input digital signal, respectively. The side walls are spaced apart from each other and the channel runs generally between the side walls.
