Ethernet
The DFE-Gold Modules
This section provides an overview of the 4H4282‐49, 4H4283‐49, 4H4203‐72 ( Figure 1‐1 ),
4H4202‐72, and 4H4284‐49 ( Figure 1‐2 ) DFE‐Gold modules.
The DFE‐Gold modules can be installed in a Matrix N1, N3, N5, N7, or E7 chassis.
The DFE‐Gold 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‐Gold module receives power and backplane connectivity when it is inserted into
the chassis.
The information concerning how to configure the DFE module features are provided in
the Enterasys Matrix DFE‐Gold Series Configuration Guide.
4H4282-49
The 4H4282‐49 is an edge‐network switch with 48, 10BASE‐T/100BASE‐TX compliant
ports, through fixed front panel RJ45 connectors and an option slot for a network
expansion module. 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.
4H4283-49
The 4H4283‐49 is an edge‐network switch with 48, 10BASE‐T/100BASE‐TX compliant
ports through four fixed front‐panel RJ21 connectors and an option slot for a network
expansion module. 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.
4H4203-72
The 4H4203‐72 has 72, 10BASE‐T/100BASE‐TX compliant ports through six front‐panel
RJ21 connectors. Each of the fixed front panel ports can operate in either half‐duplex or
Caution: Regardless of which chassis is used, the chassis system must be dedicated to
DFE-Gold modules (4xxxxx) only. Do not insert 7xxxxx modules or other legacy modules
into the same chassis with 4xxxxx modules as this will render the chassis inoperable.
