How to connect two network switches
Typical network switch. (network switch image by gajatz from

Switches allow multiple devices to connect. Connecting multiple devices forms a LAN, or local access network, which allows the connected devices to communicate. If a switch is connected to a router with Internet access, each connected device will also be able to connect to the Internet. Switches may need to be connected to allow different departments to communicate. However, as the number of connected devices rises, the network slows down.

Skill level:

Things you need

  • Crossover cable
  • 2 switches

  1. 1

    Connect one end of the crossover cable to a port on one of the network switches.

  2. 2

    Connect the other end of the crossover cable to the other network switch.

  3. 3

    Power on both switches.

Tips and warnings

  • To verify the connection, connect one of the switches to the Internet via a network router. Connect a computer to the other switch. If the computer can connect, the switches are connected and are communicating.
  • Connecting too many devices to the switches reduces the overall available bandwidth, which results in slower Internet. One way to solve this problem is to trunk the ports that are connected on the switches. Trunking basically combines the bandwidth between ports on a switch. How to trunk ports on a switch, however, is outside the scope of this article.
