In the basic configuration, 10Mbps and 100Mbps segments are separate and do not intercommunicate. An optional DFE-260S switching module (in- cluded with the DFE-916x) can be installed in any hub in the stack, making it possible to transparently bridge between 10Mbps and 100Mbps segments. In a managed hub stack, more than one DFE-260S module can be used to provide automatic redundancy.
Other add-in modules are also available, providing switched 100BASE-TX or switched 100BASE-FX connections. DFE-916x and DFE-916 hubs have one slot each for accepting slide-in modules.
Product Features
The list below highlights the features and specifications of DFE-916 series hubs:
♦Compatible with the IEEE 802.3 10BASE-T Ethernet and 802.3u 100BASE-TX Fast Ethernet industry standards for interoperability with other Ethernet/Fast Ethernet network devices.
♦Ethernet connections support Category 3 or better twisted-pair ca- bles.
♦Fast Ethernet connections support both shielded twisted pair and Category 5 unshielded twisted-pair cables.
♦Fast Ethernet connections support a maximum distance of 100 me- ters from end-station to hub, and a total network diameter of 205 meters.
♦Sixteen NWay ports per hub for connecting stations to the network.
♦An optional slide-in switching module allows bridging between 10Mbps and 100Mbps segments. Only one switching module is needed per stack, but managed hub stacks can make use of addi- tional switching modules for redundancy.
