What Is a Core Switch Backplane?

Function

A core switch located on a backplane connects edge switches. An edge switch is a switch placed where two network's hardware systems meet. Examples of edge switches include multiplexers and routers. Edge switches are also referred to as service or access nodes.

Identification

Core switch backplanes are often referred to as tandem or backbone switches. A computer's core is synonymous with its central processing unit (CPU.)

Features

The word "backplane" is often considered to be synonymous with a computer's motherboard. They control computing paths through socket connections not only to other circuit boards, but also to expansion cards and other electronic devices.

Backplanes are considered active if they contain circuitry that conducts computing functions. Passive backplanes do not contain circuitry and are not responsible for anything but serving as connectors.
