Managed Switches. Managed switches almost always have loop detection, called Spanning Tree Protocol. When a port comes up with a new link, the switch does not immediately join it to the switch fabric at-large. Instead, it segregates the new port(s) and uses STP to see if a loop would exist if the new port(s) were added to the fabric.If your power goes out, one of the safest and easiest ways to switch power to a portable generator to your electrical panel.
