Bypass / Disconnect

Silicom’s Bypass adapter supports the following mode states: Normal/inline, Bypass/Fail-To-Wire and Disconnect modes.

Normal/Inline mode

In Normal mode, the ports are independent interfaces (see Figure 6: Normal mode, one Bypass pair is illustrated).

Figure 4: Normal Mode Functional Block Diagram

Bypass/Fail-To-Wire mode

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 unconnected.

(See Figure 7: one Bypass pair illustrated)

Disconnect mode

In Disconnect mode, the transmit connections of the interfaces are disconnected from the ports. The switch / router connected to

the adapter does not detect link partner (See Figure 8):
