How does the fail-open function work

The standard Gigabit Fail-Open Kit and the 10 Gigabit Fail-Open Kit minimize the potential risks of

in-line Sensor failure on critical network links. You need to purchase these kits separately. Both copper

and optical versions of the kit are available for the one gigabit ports. A 10 Gigabit Optical Kit is

available for the 10 gigabit ports.

The Monitoring ports of the Sensors fail-close; thus, if the Sensor is deployed in-line, a hardware

failure results in network downtime. For the Monitoring ports to fail-open, you use the optional

external bypass switch provided in a Fail-Open Kit.

With the bypass switch in place, normal Sensor operation supplies power to the switch through a

control cable. While the Sensor is operating, the switch is "on" and routes all traffic directly through

the Sensor. When the Sensor fails, the switch automatically shifts to a bypass state; in-line traffic
