Single Board Computer / Introduction for ISP Series www.ieiworld.com LAN Bypass Introduction What is LAN Bypass Function Bypass Function Block Diagram LAN Bypass feature removes a single point of failure so that The bypass function block diagram shown below depicts the block essential business communication can continue while a network diagram for one pair of Local and Remote ports of the 4-port 10Base- failure is diagnosed and resolved. In the event of a power, hardware T/100Base-TX/1000Base-T Ethernet board with bypass. or software failure. Hardware Bypass will automatically activate, allowing network traffic to continue. Traffic between the LAN and ▬ Normal State System with LAN Bypass WAN is allowed without interruption. ▬ LAN By-pass State PCIe Bus Ethernet 1 Bypass Function Relay Modes LAN 1 PC1 The bypass function uses relays to route each of the two LAN ports pairs in either “bypass” mode or “normal” mode. Relay In “normal” operation the magnetics are connected A PCIe Bus Ethernet 2 to the RJ-45s. LAN 2 Relay settings for “normal” operation: PC2 Ethernet 3, 4 LAN 3 LAN 4 Relay Bypass Relays 82574L magnetics PC3 Gigabit Relay Ethernet GPIO LPC Bus Super IO Controller Controller RJ-45 Best choice from iEi RJ-45 Bypass iEi ISP series product is a PCIe LAN bypass adapter card. It have a Disable 82574L LAN bypass feature that, in the event of a system hang, power down, Relays Gigabit hardware or software failure, Hardware Bypass will automatically Ethernet Relay magnetics Controller Controller activate allowing network traffic to continue. The bypass feature can be controlled by software, or by a watchdog timer configurable for 1-16 second operation. The adapter card can be migrated In “bypass” operation the RJ-45s are connected together B with concurrent network appliance platforms for network security such that they form a piece of wire. applications and embedded box solutions.
