USB 3.0 to Dual Gigabit Ethernet Bypass Adapter

Product Description

Silicom’s USB to dual port Ethernet bypass adapter is targeted to

maintain network connectivity when system fails. Silicom’s USB to

dual port Ethernet bypass adapter supports Normal and Bypass

modes. In Normal mode, the ports are independent interfaces.

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. Silicom’s USB to dual port Ethernet

bypass adapter can Bypass its Ethernet ports on a host system failure, power off, or upon software request.

Silicom’s USB to dual port Ethernet bypass adapter includes an on board Silicom Bypass Controller with WDT (Watch Dog Timer).

The adapter’s software drivers or software application can write commands to the on board Silicom Bypass controller.

The adapter’s software drivers, Silicom Bypass controller and the Bypass circuitry provide an interface that control and manage the

mode of the adapter.
