How to Connect Multiple Network Switches
Network switches are cornerstones of good networks. They work as gatekeepers, directing traffic and allocating bandwidth to all users of the network according to their needs. Learning how to connect network switches together is crucial in building a robust network. Common network switches have from four to 16 ports where you can connect an Ethernet cable. If you need more ports than those available on a single network switch, then you need to install an additional switch.
First: Finding the appropriate spot
Install the additional network switch to minimize cable length. This saves money in cables and improves network performance. Since network switches need a power supply, it is best to choose a location near a power outlet.
Second: Connecting the new network switch
After securing a good spot for the new network switch, find an available port on the existing switch. Connect a good quality Ethernet cable between this port and any port on the new network switch. Connect additional cables to the other available ports. These cables then connect to all devices that need a network connection.
Third: Connecting the power supply
After all Ethernet cables are connected, the power supply of the network switch is now connected. If present, set the on/off switch to the on position. Status and activity LEDs should flash and signal that the device is ready to run.
Fourth: Setting IP addresses
Most network switches are capable of automatic IP conflict detection and prevention, assigning available addresses as the network grows. If a conflict occurs, the user should only need to either reset one of the network switches, preferably the one closer to the device with the conflicting address, or briefly disconnect its network cable. Once it is reconnected, the network switch assigns it a new conflict-free address.
