DFE Module Placement and Installation Rules
The DFE‐Platinum modules can be installed in a Matrix E7 (refer to “Matrix E7 Chassis
Module Placement,” below, for placement rules), Matrix N3, Matrix N5, or Matrix N7
chassis.
The 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 3‐1 shows six examples of chassis module placement. These examples are
described below along with the applicable module placement rule.
Note: Install any optional equipment before installing the DFE module into a chassis.
