Network Switches – What do they do and How do I Pick the Right One?

Geoffrey Adaire


  • When using data switches in Voice Over IP (VOIP) solutions Power over Ethernet (POE) should also be a consideration. The main advantage of Power over Ethernet (PoE) is delivery of data AND power over one Cat5e/Cat6 Ethernet cable. PoE ends the need for AC/DC power supplies and outlets. A remote installation costs less than fiber as no electrician is required. Ethernet cable costs less and is often already installed buildings.

  • Thanks Juan, that is a great point and further evidence of how strategic we must be when designing networks and their infrastructure.

  • Thanks Sal! This article really made clear the opportunities and implications of switch selection and what it is they do for a relatively non-technical person like myself.
