Passive Mode vs. Active Mode

By default, the ports in the TAP-HC0-G100C0 and the TAP-HC1-G10040 modules operate in passive mode instead of active mode:

■

In passive mode, the relays in these TAP modules are closed. This means that traffic received on one port is passed through out the other port in the pair but is never seen by the GigaVUE – it simply flows between the two ports. The default is passive mode.

Passive mode protects production links in case of power failure. The TAP always reverts to passive mode in the event of a power loss.

Note:  The Link and Activity LEDs are always off when the TAP-HC0-G100C0 or TAP-HC1-G10040 is operating in passive mode.

■

In active mode, the relays in the TAP-HC0-G100C0 or TAP-HC1-G10040 module are open. Traffic received on one port is actively regenerated out the other port in the port-pair. In addition, traffic flows through the GigaVUE, making it available to tool ports.
