The Fail-Open Kits 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. The standard Gigabit Fail-Open Kits
and 10 Gigabit Fail-Open Kits are available for the 1 and 10 gigabit ports respectively.
The Monitoring ports of the Sensors can be fail-close; thus, if the Sensor is deployed in-line fail-close, a hardware failure results in
network downtime. Except the built-in RJ-45 ports which come with built-in fail-open functionality, you use the optional external
bypass switch provided in an Active Fail-Open Kit for the Monitoring ports to fail-open.
While the Sensor is operating, the Active Fail-Open (AFO) kit is in-line and routes all trac directly through the Sensor. When
the Sensor fails, the switch automatically shifts to a bypass state; in-line trac continues to ow through the network link but is
no longer routed through the Sensor. After the Sensor resumes normal operation, the switch returns to the "inline" state, once
again enabling in-line monitoring. The port pairs with AFO kits resume inline mode after a Sensor resumes normal operation or
is in good health.
G0 supports passive fail-open mode with RJ-11 port control
G0 also supports active fail-open using a Copper and Fiber 1/10 Gigabit AFO kit.
G1 and G2 supports built-in fail-open and active fail-open mode for these interface modules:
4-port 10 GigE/1 GigE LR Optical with internal fail-open
4-port 10 GigE/1 GigE SR Optical 50 micron with internal fail-open
4-port 10 GigE/1 GigE SR Optical 62.5 micron with internal fail-open
4-port RJ-45 10 GigE with internal fail-open
6-port RJ-45 1 GigE with internal fail-open
All RJ-45 ports support active fail-open using only a Copper AFO kit.
8-port SFP/SFP+ 1/10 Gigabit
The 8-port module supports active fail-open using a Copper and Fiber 1/10 Gigabit AFO kit.
G3 supports both internal fail-open and active fail-open mode when connected to an Active Fail-Open (AFO) kit
