All SINGLEstream Aggregation Taps are either inherently passive devices or have robust power fault-tolerance passive bypass systems. The SS-100 copper tap for 10/100 only and all of the fiber tap models feature “Never Breaks the Link” technology, meaning connectivity is never interrupted and the link never changes state, even when  power is lost or being restored to the tap. Because power is required for the monitoring device to receive data from the tap ports, all models of theSINGLEstream Aggregation Tap come standard with a dual redundant power supply to ensure maximum uptime for network analysis and monitoring tools.
All Gigabit capable copper models – the SS-1200, SS-2200 and SS-4200 series, utilize a robust copper relay based power fault tolerance system that provides a passive bypass in the event of power loss. With the models it is recommended to set endpoint devices of the tapped link to Portfast or FastLearn thereby ensuring absolute minimum time for the link to re-establish itself when power is lost or restored.
