The DFE Modules

1.2 THE DFE MODULES
This section provides an overview of the DFE modules 7H4382-49 and 7H4383-49 (Figure 1-1),
7G4270-12, 7G4202-30, and 7H4203-72 (Figure 1-2). For information about features of the DFE
modules and how to configure them, refer to the Enterasys Matrix DFE-Platinum Series
Configuration Guide.
7H4382-49
The 7H4382-49 DFE module has 48, 10BASE-T/100BASE-TX compliant ports, via fixed front
panel RJ45 connectors and a slot for an optional network expansion module (NEM). The DFE
module can be installed in a Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1 chassis.
The 7H4382-49 DFE module also supports bridging between the Frame Transfer Matrix FTM1
and FTM2 backplanes in a Matrix E7 chassis. When mixing 6x1xxx, 6x2xxx, 6x3xxx, and 7x4xxx
series modules in a Matrix E7 chassis, certain hardware installation configuration rules must be
followed to ensure proper operation. These rules are covered in Chapter 3.
Each of the fixed 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 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.
The DFE module receives power and backplane connectivity when it is inserted into the
Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1 chassis.
7H4383-49
The 7H4383-49 DFE module has 48, 10BASE-T/100BASE-TX compliant ports via four fixed
front-panel RJ21 connectors and a slot for an optional network expansion module (NEM). The
DFE module can be installed in Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1
chassis.
As with the 7H4382-49, the 7H4383-49 DFE module also supports bridging between the Frame
Transfer Matrix FTM1 and FTM2 backplanes in a Matrix E7 chassis. When mixing 6x1xxx,
6x2xxx, 6x3xxx, and 7x4xxx series modules in a Matrix E7 chassis, certain hardware installation
configuration rules must be followed to ensure proper operation. These rules are covered in
Chapter 3.
Each of the fixed 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.
