Silicom’s 10 Gigabit Ethernet PCI Express Bypass front connectors server adapters are PCI-Express X8 Bypass network interface card that provides a front-panel connector, cables and LED assemblies to allow port access and LED displays at the front of the server.
Silicom’s 10 Gigabit Ethernet PCI Express Bypass front connector is designed for servers that support adding connectors at the front. The 10 Gigabit Ethernet Bypass front connector includes a closed metal bracket at the back of the server, cables and the front panel-connector installed at the front of the server.
The Silicom 10 Gigabit Ethernet PCI Express Bypass front connector offer simple integration into any PCI Express X8 to 10Gigabit Networks. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications.
The Silicom 10 Gigabit Ethernet PCI Express Bypass front connector is based on Intel 82598 Ethernet controller with two fully integrated Gigabit Ethernet Media Access Control (MAC) and XAUI ports. 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. Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.
Silicom’s 10 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.
The Silicom 10 Gigabit Ethernet PCI Express Bypass front connector can Bypass its Ethernet ports on a host system failure, power off, or upon software request. 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. Hence, in bypass mode all packets received from one port are transmitted to other port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network.
The Silicom 10 Gigabit Ethernet PCI Express Bypass front connector includes 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.

Functional Description
Silicom’s Bypass Server adapters support Normal and Bypass mode. In Normal mode, the ports are independent interfaces (see Figure 1: Normal mode, one Bypass pair is illustrated).
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)
Bypass Mode Functional Block Diagram
Silicom Bypass server adapters include an on board Controller that can Bypass the Ethernet ports on host system failure like Power Off, System hangs or software application hangs. The software programmable Watch Dog Timer (WDT) Controller detects a host system fails and it will Bypass automatically the Ethernet portsafter programmable time out interval. The WDT Controller can be software programmable enabled or disabled.
Silicom Bypass server adapters support software programmable to select Bypass or Normal mode. In Normal mode, the ports of the adapters remain independently operational.
The drivers of the adapters and the Bypass circuitry provides an interface that control and management the mode of the adapter. The adapter software driver or software application can writes commands to the on board controller. The on board controller processes the commands and activates the bypass circuitry accordingly.
After power up the default mode of theadapter is to be in Bypass mode. After driver is loaded, the adapter software driver or application can set the card to a Normal mode. After the Host system issues reset, setting of Bypass controller and circuitry are reserved.
Silicom Bypass server adapters support Disable Bypass Capability; hence, if those adapters receive Disable Bypass Capability command, the adapter does not Bypass its Ethernet ports, in this state the dual Ethernet ports are independent. The Disable Bypass Capability state is reserved also after power off. This feature enables to emulate a standard NIC. Silicom Bypass server adapters can be set to Bypass or Normal mode at power up. This setting programmable and is reserved also after power off.
