DFE Module and Interface Options

• Self‐learning configuration modules with increased reliability and fault tolerance that
reduces configuration time and maximizes uptime
• Network‐wide configuration, change, and inventory management that is easier to
install, troubleshoot, and maintain
• Reduced support and maintenance costs; decreases configuration time
• Support for a variety of converged applications including VoIP with Power‐over‐
Ethernet

DFE Module and Interface Options

This section provides an overview of the 7G4280‐19 (Figure
features of the DFE modules and how to configure them, refer to the Enterasys Matrix
DFE‐Platinum Series Configuration Guide.

7G4280-19

The 7G4280‐19 has 18, 1000BASE‐X compliant front‐panel ports that support a variety of
optional Small Form Factor Pluggable (SFP) Gigabit connections using optional Mini‐
Gigabit Interface Cards (MGBICs). There is also a slot for an optional network expansion
module (NEM).
The 7G4280‐19 can be installed in a Matrix E7, N7, N5, N3 or N1 chassis, but only
supports FTM2 data backplane interconnections in the Matrix E7 chassis. Traffic flow
from FTM2 to FTM1 can only be accomplished with a 7H4382‐25, 7H4382‐49, 7H4383‐49,
or 7H4385‐49 DFE module.
Each of the front panel ports can operate in either half‐duplex or full‐duplex mode of
operation. The duplex mode can be determined by either auto‐negotiation or manual
configuration.
The DFE module ports can be configured to provide a high level of security, control traffic
by limiting the rate of traffic accepted into the module and prioritizing traffic to expedite
the flow of higher priority traffic through the module. For a complete list of capabilities
refer to the Enterasys Matrix DFE‐Platinum Series Configuration Guide.
The DFE module receives power and backplane connectivity when it is inserted into a
Matrix E7, N7, N5, N3 or N1 chassis.
