Fail-open
Fail-open refers to a configuration that allows network traffic to continue even
if the Symantec Network Security 7100 Series appliance has a hardware or
software failure that affects one or more of its in-line interface pairs. For in-line
interface pairs on the appliance, fail-open is an option that requires the
purchase and installation of another device called the Symantec Network
Security In-line Bypass unit.

About the In-line Bypass unit
Since in-line mode by definition places the appliance into the network path, a
hardware or software failure affecting the interface pair will interrupt network
traffic, or fail closed. To avoid this you can install the In-line Bypass unit. The
bypass unit monitors the 7100 Series status, and if it senses a failure, the bypass
unit provides direct network connectivity.
There are two bypass unit models, called the 2 In-line Bypass unit and the 4
In-line Bypass unit. The two models are designed to accommodate 7100 Series
appliances with either four or eight copper monitoring interface ports. The
following table summarizes the features of the bypass unit models:
