Module Placement in a Matrix E7 Chassis
2-2 Network Requirements
In normal usage (and typical implementations) there is no need to enable/disable ports for
Link Aggregation. The default values will result in the maximum number of aggregations
possible. If the switch is placed in a configuration with its peers not running the protocol,
no aggregations will be formed and the DFE modules will function normally (that is,
Spanning Tree will block redundant paths).
For details about the commands involved with configuring the Link Aggregation
function, refer to the Enterasys Matrix DFE ‐ Platinum Series Configuration Guide .
Module Placement in a Matrix E7 Chassis
If you want to mix 6x1xxx, 6x2xxx, 6x3xxx, and 7H43xx ‐ xx series modules in the same
Matrix E7 chassis, it is necessary to have a DFE bridging module installed and follow the
instructions described in “ Module Placement and Rules ” on page 3 ‐ 7 to successfully
bridge data traffic to some or all modules in the Matrix E7 chassis. At the time of this
printing, the FTM1 ‐ to ‐ FTM2 bridging modules available are: 7H4382 ‐ 25, 7H4382 ‐ 49,
7H4383 ‐ 49, and 7H4385 ‐ 49.
1000BASE-SX/LX/ELX Network
Optional Mini ‐ GBICs installed in the 7G4280 ‐ 19 front ‐ panel ports 1 through 18, or in an
optional network expansion module provide Gigabit Ethernet connections operating at
1000 Mbps (1 Gbps). The device at the other end of the fiber ‐ optic connection must meet
IEEE 802.3 ‐ 2002 Gigabit Ethernet requirements for the devices to operate at Gigabit speed.
Refer to Appendix A for further details on Mini ‐ GBIC specifications.
1000BASE-T Network
The 7G4280 ‐ 19 and optional network expansion module also support Mini ‐ GBICs for
copper wire connections through RJ45 connectors, which can operate up to 1000 Mbps.
The device at the other end of the twisted pair segment must meet IEEE 802.3 ‐ 2002
1000BASE ‐ T network requirements for the devices to operate at Gigabit speed.
Note: The optional Mini-GBIC copper wire connection supports Category 5 UTP cabling
with an impedance of between 85 and 111 ohms for 1000 Mbps operation.
