4.1.1 Normal Active Bypass

Traffic will flow between the network and appliance ports as shown in the following diagram. If heartbeat
signals are not received within the timeout period, traffic will be routed between N1 and N2. Ports A1 and
A2 will be bypassed. Heartbeat packets will continue to be sent out the Appliance port. This allows the
module to automatically route traffic back through the appliance once it is repaired, or placed back into
service.
