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‐Platinum modules (7xxxxx) 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‐Platinum 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
DFE‐Platinum 7H4382‐25, 7H4382‐49, 7H4383‐49, or 7H4385‐49. Installation Guides for
these bridging modules are located on the Enterasys Networks World Wide 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‐Platinum 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 DFE modules.

Module Placement and Rules

The DFE modules can be installed in a Matrix
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 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
described below along with the applicable module placement rule.
3‐2 shows five examples of chassis module placement. These examples are
