3D7110/7120
The 3D7110/7120 is delivered with eight copper port sensing interfaces, or eight
fiber port sensing interfaces, each with configurable bypass capability. The
following illustration of the front of the chassis indicates the location of the
sensing interfaces.

You can use these connections to passively monitor up to eight separate network
segments. You can also use paired interfaces in inline or inline with bypass mode
to deploy the device as an intrusion prevention system on up to four networks.
If you want to take advantage of the device’s automatic bypass capability, you
must connect either the two interfaces on the left or the two interfaces on the
right to a network segment. Automatic bypass capability allows traffic to flow
even if the device fails or loses power. After you cable the interfaces, you use the
web interface to configure a pair of interfaces as an inline set and enable bypass
mode on the inline set.
