Dual-Speed Stackable Hubs User’s Guide 1 NTRODUCTION 1 I This chapter introduces DFE-916 series dual-speed stackable hubs, as well as giving some background information about the technology the hubs use. Product Description D-Link DFE-916 series dual-speed stackable Ethernet/Fast Ethernet hubs are designed to allow easy migration and integration between 10Mbps Ethernet and 100Mbps Fast Ethernet, while providing manageability and flexibility in cable connections. Each hub can operate with both I

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

technologies, especially when network hosts are being gradually migrated to new Fast Ethernet connections. A dual-speed hub is actually two repeaters in one enclosure. The 10Mbps repeater receives Ethernet transmissions from any of its ports, and retrans- mits them to all other ports operating at 10Mbps. Similarly, the 100Mbps repeater retransmits Fast Ethernet transmissions from ports operating at 100Mbps to all other ports operating at the same speed. 10Mbps Repeater 100Mbps Repeater NWay De

Since Fast Ethernet is compatible with all 10Mbps Ethernet environments, it provides a straightforward upgrade with- out wasting the company’s existing investment in hardware, software, and trained personnel. Cables and Connectors Category 5 unshielded twisted-pair (UTP) cables and shielded twisted-pair (STP) cables are both supported. Category 5 UTP cables use the same RJ- 45 connector used with 10BASE-T, wired in the same configuration. Topology A Fast Ethernet work

Dual-Speed Stackable Hubs User’s Guide Network Diameter Network diameter, which is the distance between two end-stations in the same collision domain, is the primary difference between traditional Ethernet and Fast Ethernet. Due to the increased speed in Fast Ethernet and adherence to the EIA/TIA 568 wiring rules, the network diameter of a Fast Ethernet collision domain is limited to 205 meters; in contrast, the maximum 10BASE-T Ethernet collision domain diameter can be up to 500 meters.
