Port Fiber Gigabit Ethernet Express Module Bypass Server Adapter

Product Description

Silicom’s Quad Port fiber Gigabit Ethernet Express Module

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 Quad Port fiber Gigabit Ethernet Express Module

Bypass server adapter is targeted to inline network system that

maintains network connectivity when system fails.

Silicom’s Quad Port Fiber Gigabit Ethernet Express Module 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 / route cable disconnection.

Silicom’s Quad Port Fiber Gigabit Ethernet Express Module 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 Quad Port Fiber Gigabit Express Module 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.

Silicom’s Quad Port Fiber Gigabit Ethernet Express Module Bypass server adapter is based on Intel 82580 Quad Port Gigabit

Ethernet MAC+PHY of Intel Controller.
