Backplane Connections and Installation Rules
The following sections describe the FTM1 and FTM2 backplane connections, and the
hardware configuration rules when installing first (6x1xx), second (6x2xx), third (6x3xx),
and fourth (7xxxxx) generation modules into the same Matrix E7 chassis.
FTM1 and FTM2 Connectivity
The Matrix E7 (6C107) chassis has backplanes referred to as FTM1 and FTM2. The 7xxxxx
DFE modules use FTM2 for high speed communication to each other and operate as one
switching unit with a single IP address. The traffic through these modules does not
connect to FTM1 except through an FTM bridging module such as the 7H4382‐25,
7H4382‐49, 7H4383‐49, or the 7H4385‐49.
These DFE modules have connections to both FTM1 and FTM2 backplanes, enabling them
to route frames between the two backplanes and all modules in the 6C107 chassis.
However, the older first (6x1xx), second (6x2xx), and third (6x3xx) generation modules are
still managed using their own Local Management and are not subject to management by
the DFE module management entity.
The Matrix N3 (7C103) and Matrix N7 (7C107) chassis have only FTM2 connections and
support only DFE modules. The Matrix N5 (7C105‐P) has FTM2 connections and also
supports PoE‐compliant DFE modules.
Module Placement and Rules
Depending on the modules being installed in the Matrix E7 chassis and to help ensure
proper operation, consider the following examples and rules for module placement in the
chassis. Figure
described below along with the applicable module placement rule.
The Matrix N1, Matrix N3, Matrix N5, and Matrix N7 chassis support only DFE Series
modules and there are no particular rules for installing modules.
Note: A lowercase x indicates the general use of an alphanumeric character (for example,
6x1xx, the x's indicate a combination of numbers or letters).
