PE2G4BPI80 Bypass Adapter

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

Product Description

Silicom’s Quad 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 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.
