PE2G2BPI80 Bypass Adapter

Dual Ports Copper Gigabit Ethernet PCI Express Bypass Server Adapter Intel® 82580DB Based

Product Description

Silicom’s Dual Port Copper Gigabit Ethernet PCI Express Bypass server

adapter is a PCI-Express X4 network interface card that contains four ports

on a PCI-E adapter.

Silicom’s Dual 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 Dual 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 Dual Port Copper Gigabit Ethernet PCI Express Bypass server adapters are based on Intel 82580DB Ethernet controller.
