Connectivity
7GR4270-12
The 7GR4270 ‐ 12 DFE module has 12 front panel option ports that support 1000BASE ‐ X Gigabit
Ethernet through optional Mini ‐ GBICs. For Mini ‐ GBIC specifications, refer to Appendix A .
7GR4202-30
The 7GR4202 ‐ 30 DFE module has 30, 10BASE ‐ T/100BASE ‐ TX/1000BASE ‐ T compliant ports
through fixed front panel RJ45 connectors.
7GR4280-19
The 7GR4280 ‐ 19 DFE module has 18, 1000BASE ‐ X compliant, Small Form Factor Pluggable (SFP)
fixed front ‐ panel port slots for Gigabit Ethernet connections using optional Mini ‐ Gigabit Interface
Cards (Mini ‐ GBICs). The port slots enable you to install a mix ‐ and ‐ match number of SFPs to meet
a need for various Gigabit Ethernet connections. For Mini ‐ GBIC specifications, refer to
Appendix A .
There is also a slot for an optional network expansion module (NEM). Refer to the
Enterasys Networks web site for a current listing of the available NEMs. Specific installation
instructions are shipped with each NEM.
7KR4290-02
The 7KR4290 ‐ 02 DFE module has 2, 10 ‐ Gbps Ethernet port slots on the front panel that can
support one or two 10 ‐ Gbps XENPAK PHYs for high speed uplinks from the chassis DFE Ethernet
switch system. With two 10 ‐ Gbps PHYs installed in the 7KR4290 ‐ 02, a shared uplink of up to
10 Gbps can be provided from the DFE switching system to two network edge connections from a
Matrix E7, N7, N5, N3 or N1 chassis to a core data center. For the XENPAK PHY specifications,
refer to Appendix A .
Note: The 7GR4270-12, 7GR4202-30, 7GR4280-19, and 7KR4290-02 DFE modules can be
installed in a Matrix E7, N7, N5, N3 or N1 chassis, but only support FTM2 data backplane
interconnections in the Matrix E7 chassis. Traffic flow from FTM2 to FTM1 can only be
accomplished using a bridging module such as the 7H4382-25, 7H4382-49, 7H4383-49, or
7H4385-49.
