DFE-Platinum 7H4385-49 PoE Module
This section provides an overview of the 7H4385 ‐ 49 ( Figure 1 ‐ 1 ). For information about
the DFE module features and how to configure them, refer to the Enterasys Matrix
DFE ‐ Platinum Series Configuration Guide .
The 7H4385 ‐ 49 has 48, 10BASE ‐ T/100BASE ‐ TX, PoE ‐ compliant ports that are accessed
through the fixed front panel RJ45 connectors. There is also an slot for an optional
network expansion module (NEM). The DFE module can be installed in a Matrix E7,
Matrix N1, Matrix N3, Matrix N5, or Matrix N7 chassis.
The 7H4385 ‐ 49 DFE ‐ Platinum module also supports bridging between the Frame Transfer
Matrix FTM1 and FTM2 backplanes in a Matrix E7 chassis. When mixing 6x1xxx, 6x2xxx,
6x3xxx, and 7H43xx ‐ xx series modules in a Matrix E7 chassis, certain hardware
installation configuration rules must be followed to ensure proper operation. These rules
are covered in “ Module Placement and Installation Rules ” on page 3 ‐ 4.
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, Matrix N3, or Matrix N1 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 eight
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.
Note: Only an N-POE Power System can be connected to the 48 Vdc ~ 20 A Maximum
Optional Power Input connector of a series PoE-compliant DFE module such as the
7H4385-49.
