10BASE-T Network
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 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 Matrix DFE‐Gold Series Configuration Guide.
10BASE-T Network
When connecting a 10BASE‐T segment to any of the fixed front panel ports of the
4G4202‐72 or 4G4282‐49, 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
The fixed front panel ports of the 4G4202‐72 or 4G4282‐49 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.
1000BASE-SX/LX/ELX Network
The optional Mini‐GBICs provide a Gigabit Ethernet connection to the optional
7G‐6MGBIC‐A interface module to provide fiber‐optic connections operating at
1000 Mbps (1 Gbps). Other Mini‐GBICs may support different types of cabling
connections. 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.
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 “
100BASE-TX Network ” on page 2-2 for
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
10, 100, or 1000 Mbps and can automatically sense the port speed of the other device and
adjust its speed accordingly.
