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

Product Description

Silicom’s Quad Port fiber Gigabit Ethernet Express Bypass server

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

Gigabit Ethernet ports on a PCI-E adapter.

The Silicom’s Quad Port fiber Gigabit Ethernet Express Bypass server

adapter is targeted to inline network system that maintains network

connectivity when system fails.

Silicom’s Quad Port Fiber Gigabit Ethernet Express Bypass server adapter supports Normal, Bypass and Disconnect modes. In

Normal mode, the ports are independent interfaces. In Bypass mode, all packets received from one port are transmitted to the

adjacent port. In Disconnect mode, the adapter simulates switch / route cable disconnection.

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 Fiber Gigabit Ethernet Express Bypass server adapter is based on Intel 82580 Quad Port Gigabit Ethernet

MAC+PHY of Intel Controller.

Silicom’s Quad Port Fiber Gigabit Ethernet Express Bypass server adapter can Bypass or Disconnect its Ethernet ports on a host

system failure, power off, or upon software request. 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 Fiber Gigabit Express Module Bypass server adapter

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.
