4G4205-72
The 4G4205‐72 has 72, 10BASE‐T/100BASE‐TX/1000BASE‐T, PoE‐compliant ports that are
accessed through the fixed front panel RJ45 connectors. The DFE module can be installed
in a Matrix E7, Matrix N3, Matrix N5, or Matrix N7 chassis. (See
Figure 1‐2 on page 1‐6.)
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‐Gold 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.
