Net Optics 10 GigaBit LR iBypass Switch with Heartbeat - network bypass unit

The iBypass Switch monitors the attached device by sending a Heartbeat packet to the device. If the iBypass Switch does not receive the Heartbeat response, it automatically switches network traffic to bypass the unresponsive device - even if the device is still receiving power. The iBypass continues to send the Heartbeat, and will restore traffic flow through the device as soon as the link is restored.
