9 How the Switch Can Be Used Switching When a network of r epeater hubs is i n operation, any information that is sent by the workstations is passed around the whole network (regar dless of the destination of the information). This can result in a lot of unnecessary traffic that can slow the network down.
10 Connecting 10BASE-T and 1 00BASE-TX Networks The 10/100 ports can each be conne cted to either a 10BASE-T or 100BASE-TX ne twork. If y ou have both types of network, you ca n join them togethe r using the Switch allowing all your workstations to communicate.
11 Stacking the Un its T ogether The Rubber Feet The four self-adhesive rubber feet prevent your switch fr om moving around on your desk. Only stick the feet to the marked areas at each corner of the underside of your switch if you intend to pl ace the unit directly on top of the desk.
