The DFE Modules
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.
7G4270-12
The 7G4270-12 DFE module has 12, 1000BASE-X compliant ports. These ports are Small Form
Factor Pluggable (SFP) fixed front panel port slots for Gigabit fiber-optic connections via optional
Mini-Gigabit Interface Cards (Mini-GBICs). The 7G4270-12 DFE module can be installed in a
Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1 chassis, but only supports FTM2 data
backplane interconnections in the Matrix E7 chassis. Interconnection from FTM2 to FTM1 can
only be accomplished via a bridging module such as the 7H4382-25, 7H4382-49, 7H4383-49, or
7H4385-49.
7G4202-30
The 7G4202-30 DFE module has 30, 10BASE-T/100BASE-TX/1000 BASE-T compliant ports
via fixed front-panel RJ45 connectors. The 7G4202-30 DFE module can be installed in a
Matrix E7, Matrix N7, Matrix N5, Matrix N3, or Matrix N1 chassis, but only supports FTM2 data
backplane interconnections in the Matrix E7 chassis. Interconnection from FTM2 to FTM1 can
only be accomplished via a bridging module such as the 7H4382-25, 7H4382-49, 7H4383-49, or
7H4385-49.
7H4203-72
The 7H4203-72 DFE module has 72, 10BASE-T/100 BASE-TX ports via six front-panel RJ21
connectors. The 7H4203-72 DFE module can be installed in a Matrix E7, Matrix N7, Matrix N5,
Matrix N3, or Matrix N1 chassis, but only supports FTM2 data backplane interconnections in the
Matrix E7 chassis. Interconnection from FTM2 to FTM1 can only be accomplished via a bridging
module such as the 7H4382-25, 7H4382-49, 7H4383-49, or 7H4385-49.
