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), and third (6x3xx) generation
modules, and DFE modules (7xxxxx) into the same Matrix E7 chassis.
3.3.1

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 DFE module such as the 7H4382-25, 7H4382-49, 7H4383-49, or the
7H4385-49.
Note: For more information about the 7H4382-25, 7H4382-49, 7H4383-49, and
7H4385-49 DFE modules, refer to the Enterasys Networks web site:
http://www.enterasys.com/support/manuals
The FTM bridging modules have connections to both FTM1 and FTM2 backplanes, which enables
them 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), Matrix N5 (7C105-P), and Matrix N7 (7C107)
chassis have only FTM2 connections and support only Matrix DFE-Series modules. The Matrix
N5 chassis also has backplane power connections to support DFE-Series PoE modules.
3.3.2

Module Placement and Rules

The DFE module can be installed in a Matrix E7 (refer to
Placement," below, for placement rules), Matrix N1, Matrix N3, Matrix N5, or Matrix N7 chassis.
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.
Matrix E7 Chassis, Module Placement
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 3-1 shows five examples of chassis module placement. These examples are described
below along with the applicable module placement rule.
