Ring Topologies - HP 2920 Installation And Getting Started Manual

Ring Topologies

Up to 4 switches may also be connected in closed ring topologies. Ring
topologies afford some protection from a single failure because
communications between the switches continues, in a direction away from
the failure. Therefore ring topologies are recommended.
A typical ring topology is illustrated in Figure 2-22.
