Power; Power Failure; Fast Failover (1G) - ProfiTap C1-1G-RG2 Product Manual

1.5 Power

The C1-1G-RG2 TAP can use redundant powering, guaranteeing continued operation in
case power from one of the power inputs were to become unavailable. Two LEDs show the
presence of power.

1.6 Power Failure

When the TAP becomes unpowered, it activates its bypass circuits, connecting network
ports A and B together. Monitor ports are disabled when the TAP is unpowered.

1.6.1 Fast Failover (1G)

When a power transition event occurs, the network devices renegotiate the link. This
operation can take up to 5 seconds depending on network configuration and can cause
a network topology reconfiguration. The Fast Failover feature helps to reduce this time by
trying to keep the link up without renegotiation during the power change event.
With Fast Failover, the network path unavailability lasts between 30 and 300 ms.
