The Dfe-Platinum Module - Enterasys Matrix 7H4284-49 Hardware Installation Manual

The DFE-Platinum Module

1.1 THE DFE-PLATINUM MODULE
This section provides an overview of the 7H4284-49 DFE-Platinum module (Figure 1-1). For
information about features of the module and how to configure it, refer to the Enterasys Matrix
DFE-Platinum Series Module Hardware Installation Guide.
7H4284-49
The 7H4284-49 DFE module has 48, 100BASE-FX compliant ports, via fixed front panel MT-RJ
connectors and a slot for an optional network expansion module (NEM). The DFE module can be
installed in a Matrix N1, N3, N5, N7, and Matrix E7 chassis, but only supports FTM2 data
backplane interconnections in the Matrix E7 chassis. Interconnection from FTM2 to FTM1 can
only be accomplished through an FTM bridging module such as the DFE module 7H4382-25,
7H4382-49, 7H4383-49, or the 7H4385-49, as described in Section 3.3.
Each of the fixed front panel ports of the 7H4284-49 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 N1, Matrix N3, Matrix N5, Matrix N7, or Matrix E7 chassis.
