Backplane Connections and Installation Rules

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.
The 7H4382‐49 has a connection to both FTM1 and FTM2 backplanes, which enables the
7H4382‐49 to switch 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 N1 (7C111), 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 3‐5 shows five examples of chassis module placement. These examples are 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 (e.g., 6x1xx, the x's
indicate a combination of numbers or letters).
