Module Placement in a Matrix E7 Chassis
no aggregations will be formed and the DFE‐Platinum 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 7x4xxx series modules in the same
Matrix E7 chassis, it is necessary to have a DFE‐Platinum module FTM1‐to‐FTM2 bridging
module installed in the chassis and also follow the module placement rules described in
the section, "Backplane Connections and Installation Rules," on page 3‐3 to successfully
bridge data traffic to some or all modules in the chassis.
FTM Bridge Function and Network Expansion Module
Unlike the 7H4203‐72, 7H4382‐49, 7H4383‐49, and 7H4385‐49 DFE‐Platinum bridge
modules (not described in this guide)
function and an optional network expansion module at the same time without
restrictions.
10BASE-T Network
When connecting a 10BASE‐T segment to any of the module fixed front panel ports of the
7H4382‐25, ensure that the network meets the Ethernet network requirements of the
IEEE 802.3‐2002 standard for 10BASE‐T. Refer to the Cabling Guide for details.
100BASE-TX Network
Fixed front panel ports of the 7H4382‐25 provide a connection that supports Category 5
UTP cabling. The device at the other end of the twisted pair segment must meet IEEE
802.3‐2002 100BASE‐TX Fast Ethernet network requirements for the devices to operate at
100 Mbps. Refer to the Cabling Guide for details.
2-2 Network Requirements
Note: If a port is to operate at 100 Mbps, Category 5 cabling must be used. Category 3
cabling does not meet 100 Mbps specifications. For 10 Mbps operation only, Category 3 or
Category 5 cabling can be used. Refer to
information about 100BASE-TX networks and cabling.
Note: The fixed ports of the module support Category 5 UTP cabling with an impedance
between 85 and 111 ohms for 100 Mbps operation.
The module is capable of operating at either 10 or 100 Mbps. The module automatically
senses the speed of the other device and adjusts its speed accordingly.
