3.4 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.
3.4.1 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 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.
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).
