Chapter 3: Installation Typical Network Topology in Deployment A hierarchical network with minimum levels of switches may reduce the timing delay between the server and the client station. This approach will minimize the number of switches in any one path, lower the possibility of network loops, and improve network efficiency. If more than two switches are connected in the same network, select one switch as the Level 1 switch and connect all other switches to it at Level 2. We recommend conne
