PCIExpressDualPortCopper Gigabit Ethernet Bypass Server Adapter (Intel I350AM2 based)
LR-LINK Dual Port Copper Gigabit Ethernet PCI Express Bypass Server adapter is PCI-Express X4 Copper Gigabit Ethernet network interface card that is based on a single chip, non-Bridged Dual port GBE controller. LR-LINK Dual Port Gigabit Ethernet Bypass server adapter supportsNormal, Disconnect and Bypass modes. InNormalmode, the ports are independent interfaces. In Bypass mode, all packets received from one port are transmitted to adjacent port. In Disconnect mode, the adapter simulates switch / rout cable disconnection. In Bypass mode, the connections of the Ethernet ports are disconnected from the system and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. Hence, in bypass mode all packets received from one port are transmitted to the adjacent port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network.
In Disconnect mode, the adapter simulates switch / router cable disconnection. In Disconnect mode, the switch / router does not detect link partner of the adapter.
LR-LINK Dual Port Copper Gigabit Ethernet PCI Express Bypass server adapters include an on board WDT (Watch Dog Timer) controller. The adapters software drivers or software application can write commands to the on board WDT controller. The adapters software drivers, WDT controller and the Bypass circuitry provide an interface that control and manage the mode of the adapter. LR-LINK Dual Port Copper Gigabit Ethernet PCI Express Bypass Server adapter is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
