Backplane Connections and Installation Rules
3-4 Installation
The DFE FTM bridging modules have a connection 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‐Diamond module management entity.
The Matrix N3 (7C103) and Matrix N7 (7C107) chassis have only FTM2 connections and support
only DFE‐Diamond modules.
Module Placement and Rules
The DFE series modules can be installed in a Matrix E7, Matrix N1, Matrix N3, Matrix N5, or
Matrix N7 chassis. When installing the modules into one of these chassis, make sure to consider
the following placement rules for the appropriate chassis and module mix.
Matrix N3 Chassis, Module Placement
The Matrix N3 chassis slots 1 through 3 will support only DFE‐Diamond modules.
Rule: There are no particular rules for installing DFE‐Diamond modules into a Matrix N3 chassis.
Matrix N7 Chassis, Module Placement
The Matrix N7 chassis slots 1 through 7 will support only DFE‐Diamond modules.
Rule: There are no particular rules for installing DFE‐Diamond modules into a Matrix N7 chassis.
Matrix E7 Chassis
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 six examples of chassis module placement. These examples are described below
along with the applicable module placement rule.
Example 1 ( Figure 3-1
,
A)
Shows the chassis fully populated with DFE‐Diamond modules (7xxxxx). These modules
communicate with each other via the FTM2 chassis backplane and act as a single switching entity
with one IP address. The DFE‐Diamond modules are configured using a Command Line Interface
set of commands.
Rule: DFE‐Diamond modules can be installed in any available chassis slot in the Matrix E7
chassis.
