The network topology is of great importance, without knowing that, any changes of cabling may result in partial or entire system not working properly. Generally, the existing service provider should provide any information needed such as a diagram. Without it, a reverse engineering process has to be taken, which is time-consuming and not guarenteed to be successful. Reverse engineering will inevitably cause network down for some computers. (Depending on its complexity, Reverse Engineering cost ranges from $399 to $1500). In the worst case, a new network topology has to be redesigned, with routers and switches reset and reconfigured.
