quad port copper gigabit ethernet pci express gen 2.0 bypass serveradapter intel® 82580 based

silicom’s quad port copper gigabit ethernet pci express bypassserver adapter is a pci-express x8 network interface card thatcontains four ports on a pci-e adapter.

silicom’s quad port gigabit ethernet bypass server adapter supportsnormal, disconnect and bypass modes. in normal mode, the ports areindependent interfaces. in bypass mode, all packets received fromone port are transmitted to adjacent port.

in disconnect mode, the adapter simulates switch / rout cabledisconnection. in bypass mode, the connections of the ethernetports are disconnected from the system and switched over to theother port to create a crossed connection loop-back between theethernet ports. hence, in bypass mode all packets received from oneport are transmitted to the adjacent port and vice versa. thisfeature enables to bypass a failed system and provides maximum uptime for the network.

in disconnect mode, the adapter simulates switch / router cabledisconnection. in disconnect mode, the switch / router does notdetect link partner of the adapter. silicom’s quad port coppergigabit ethernet pci express bypass server adapters include an onboard wdt (watch dog timer) controller. the adapter’s softwaredrivers or software application can write commands to the on boardwdt controller. the adapter’s software drivers, wdt controller andthe bypass circuitry provide an interface that control and managethe mode of the adapter.

silicom’s quad port copper gigabit ethernet pci express bypassserver adapters are based on intel 82580eb ethernet controller withquad fully integrated gigabit ethernet media access control (mac)and phy. in addition to managing mac and phy ethernet layerfunctions, the controller manages pci express packet traffic acrossits transaction, link, and physical/logical layers.

silicom’s quad port copper gigabit ethernet pci express bypassserver adapters are the ideal solution for implementing multiplenetwork segments, mission-critical high-powered networkingapplications and environments within high performance servers.
