Chapter 3: Configuring Your FN10
In some wiring closets, it may be easier to connect two FN10s
NOTE
via an Ethernet concentrator. However, you must make sure
that there are no other devices connected to the Ethernet
concentrator.
Trunk Groups
Each set of connections between two FN10s is called a Trunk Group. You
can create several Trunk Groups to interconnect your FN10s. Each FN10
can have up to four Trunk Groups.
For example, if you have three FN10s (A, B, and C), as shown in
Figure 3-2, you could connect them using a single Ethernet segment.
However, that would limit the interconnection to 10 Mbps. To solve this
problem, you could connect A to B with one Trunk Group, and connect
B to C with a second Trunk Group.
