Description
The code is a TikZ picture that creates a diagram of a network switch with multiple blades, edge switches, and direction switches. The switches are arranged in a hierarchy where the direction switches control the edge switches, which in turn control the blades.
The diagram consists of three sets of switches arranged horizontally using chains. The first set of switches are the two direction switches, labeled "Direction Switch" and "Direction Switch 2". The second set of switches are the edge switches, which are connected to the direction switches and labeled "Edge Switch 1" through "Edge Switch 56". The third set of switches are the blade switches, which are connected to the edge switches and labeled "Blade 00" through "Blade 17".
The blades are represented as vertical blocks labeled with their ID numbers. The edge switches are represented as horizontal blocks connected to the blades via arrows. The direction switches are not connected to the blades, but rather to the edge switches via chains. The diagram also includes a bounding box that encloses a set of blades and is labeled with the chassis number.
The styles for the switches are defined using \tikzset command. The edge switches are filled with blue, the blade switches are filled with red, and the direction switches are filled with yellow. The arrows are defined using the arrow style, and the boxes are positioned using the positioning library. The diagram also uses the calc library to position the bounding boxes.
