As seen in example above running and routing cabling can be quite complex and is definitely the most time-consuming part of drawing process. Additionally in big drawings some areas can get really “busy” with lots of cabling and make the drawing to hard read.
Examples of such busy areas would be switches, like Cluster Interconnect and/or Front-End 10GbE switches. Other example would be High-End Storage controllers with many PCI slots filled with even more ports.
So how about leaving the cables out?
For documentation purposes you could use just port assignment boxes. Fill in correct port information into the boxes, skip cabling all together and you are done.
