Quad Port Copper Gigabit Ethernet Express Module Bypass Server Adapter

Product Description

Silicom’s Quad Port Copper Gigabit Ethernet ExpressModule Bypass

server adapter is a PCI-Express X8 network interface card that contains

four ports on a PCI-E adapter.

Silicom’s Quad Port Gigabit Ethernet Bypass server adapter supports

Normal and Bypass modes.

In Normal mode, 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.

Silicom’s Quad Port Copper Gigabit Ethernet ExpressModule Bypass server

adapters include 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 Copper Gigabit Ethernet ExpressModule Bypass server

adapters are based on Intel 82580EB Ethernet controller with quad fully integrated Gigabit Ethernet Media Access Control (MAC)

and PHY.

In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its

transaction, link, and physical/logical layers.
