Niagara 2831 family is a Single-segment 40 Gigabit Intelligent Active Bypass Switch family with extensive failover/bypass capabilities and 8 optional Link Aggregation TAP Ports supported for flexible port monitoring. The active bypass enables plug and play connectivity, includes an auto heartbeat, and does not require additional drivers to be installed on connected appliances. The unit possesses management functionality that can be utilized via an extensive web GUI or CLI which enables flexibility and multiple configurations. The Niagara 2831 passive bypass feature automatically switches the network traffic upon power failure of an attached in-line device, preserving network connectivity.

When Niagara 2831 detects an appliance malfunction such as a software crash, system failure or loss of power, the network traffic continues to flow through the network link, but is no longer routed through the in-line device. This ensures that inline network devices can be removed and replaced without network downtime. Once the system is back up or the power is restored to the appliance, network traffic is seamlessly diverted back to the in-line device, allowing it to resume its inline functions.
