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.
2.2 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 7H4382-25, 7H4382-49, 7H4383-49, or 7H4385-49
DFE module installed and also follow the module placement rules described in Section 3.4 to
successfully bridge data traffic to some or all modules in the chassis.
2.3 FTM BRIDGE FUNCTION AND NETWORK EXPANSION MODULE
The 7H4382-25, 7H4382-49, 7H4383-49, and 7H4385-49 DFE modules do not support both the
FTM bridging function and an optional NEM at the same time. With an optional NEM installed,
the FTM bridging function is disabled. In either of these cases, all ports of the 7H4382-49 or
7H4383-49 remain active.
2.4 10BASE-T NETWORK
When connecting a 10BASE-T segment to any of the module fixed front panel ports of the
7H4382-49,
7H4383-49, or 7H4203-72, 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.
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 Section 2.5 for information about
100BASE-TX networks and cabling.
