Silicom's Dual Port fiber Gigabit Ethernet Bypass server adapter is a PCI-Express X4 network interface card that contains four Gigabit Ethernet ports on a PCI-E adapter. The Silicom's Dual Port fiber Gigabit Ethernet Bypass server adapter is targeted to inline network system that maintains network connectivity when system fails.
Silicom's Dual Port Fiber Gigabit Ethernet Bypass server adapter supports normal, bypass and disconnect modes. In normal mode, the ports are independent interfaces. In bypass mode, all packets received from one port are transmitted to the adjacent port. In Disconnect mode, the adapter simulates switch / rout cable disconnection.
Silicom's Dual Port Fiber Gigabit Ethernet Bypass server adapter can bypass or disconnect its Ethernet ports on a host system failure, power off, or upon software request. 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. Silicom's Dual Port Fiber Gigabit Bypass server adapter includes an on board WDT (Watch Dog Timer) controller. The adapter's software drivers or software application can write commands to the on board WDT controller. The adapter's software drivers, WDT controller and the Bypass circuitry provide an interface that control and manage the mode of the adapter.Product Highlights
