Backplane Connections and Installation Rules
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).
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. Installation Guides for these bridging modules are located on the Enterasys Networks World Wide Web site: http://www.enterasys.com/ support/manuals.
