DFE Module and Interface Options
This section provides an overview of the 7G4285‐49 (Figure 1‐1) and 7G4205‐72
(Figure 1‐2). For information about the DFE module features and how to configure them, refer to the Enterasys Matrix DFE‐Platinum Series Configuration Guide.
7G4285-49
The 7G4285‐49 has 48, 10BASE‐T/100BASE‐TX/1000BASE‐T, PoE‐compliant ports that are accessed through the fixed front panel RJ45 connectors. There is also an option slot for an network expansion module (NEM). The DFE module can be installed in a Matrix E7, Matrix N3, Matrix N5, or Matrix N7 chassis. (See Figure 1‐1 on page 1‐3.)
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 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 the Matrix E7, Matrix N7, Matrix N5, or Matrix N3 chassis. The power to support the DFE module connections to 802.3af PoE‐compliant 48 Vdc PDs (powered devices) can be from the backplane of a Matrix N5 chassis or from an optional external Matrix N‐POE Power System.
The Matrix N‐POE Power System can provide 48 Vdc to support up to seven
PoE‐compliant DFE modules. The connection from the N‐POE Power System is by way of the 48 Vdc ~ 20 A Maximum, optional Power Input connector on the front panel of the DFE module.
