Tags & Features
Moxa’s OBU-102 fiber-optic bypass units add bypass relay functionality to any network node. In linear network topologies, a single power outage or node failure can disrupt communications to all downstream devices, potentially taking an entire network segment offline. With relay bypass enabled, the failed node is automatically bypassed, allowing the rest of the network to continue operating without interruption. Bypass Relay Functionality The OBU-102 Series is installed between a network node and the network infrastructure to provide bypass relay functionality for switches that do not natively support it. During normal operation, the OBU-102 functions as a gateway, forwarding traffic between the network and the connected switch. In the event of a power loss, the OBU-102 automatically bypasses the unpowered switch and transparently forwards network traffic to the next node in the chain.
