Quad Port Copper Gigabit Ethernet PCI Express Gen 2.0 Bypass Server Adapter Intel® 82580 Based

Product Description

Silicom’s Quad Port Copper Gigabit Ethernet PCI Express 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, Disconnect 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

PCI Express 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 PCI Express 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.

Silicom’s Quad Port Copper Gigabit Ethernet PCI Express Bypass server adapters are the ideal solution for implementing multiple

network segments, mission-critical high-powered networking applications and environments within high performance servers.
