EOL - PE2G2BPI80 Bypass Adapter

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

This product has been discontinued – EOL Notification

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.

Functional Description

Silicom’s Dual Port Bypass adapter supports Normal, Bypass and Disconnect modes. In Normal mode, the ports are independent interfaces (see Figure 1: Normal mode, one Bypass pair is illustrated).

Figure 1: Normal Mode Functional Block Diagram

In Bypass mode, the connections of the Ethernet network ports are Disconnected from the interfaces and switched over to the other port to create a crossed connection loop-back between the Ethernet ports. The connections of the interfaces are left not connected. (See Figure 2: one Bypass pair illustrated)

Figure 2: Bypass Mode Functional Block Diagram

In Disconnect mode, the transmit connections of the Ethernet network ports are Disconnected from the interfaces. (See Figure 3: one Bypass pair illustrated)

Figure 3: Disconnect Mode Functional Block Diagram

Silicom’s Dual Port Bypass adapter supports software programmable to select Normal, Bypass or Disconnect modes.

Silicom’s Dual Port Bypass adapter supports Disable Bypass, Disable Disconnected capabilities; hence, if those adapters receive Disable Bypass capability / Disable Disconnect commands, the adapter does not bypass / does not disconnect its Ethernet ports, The Disable Bypass Capabilities are reserved also after power off. This feature enables to emulate a standard NIC.

Silicom’s Dual Port Bypass adapter supports Disable supports setting the default mode at power up and power off. Those setting are reserved also after power off.
