INTRODUCTION
This chapter introduces the DFE-908 series stackable dual-speed Fast Ethernet/Ethernet Hubs, as well as giving some background information about the technology the hubs use.
Product Description
The D-Link DFE-908 series stackable dual-speed Fast Ethernet/Ethernet Hubs are designed to allow easy migration and integration between 10Mbps Ethernet and 100Mbps Fast Ethernet, while providing flexibility in cable connections.
The DFE-908 series hubs can operate with either IEEE 802.3 10BASE-T connections (twisted-pair Ethernet operating at 10 megabits per second), or IEEE 802.3u 100BASE-TX connections (twisted-pair Fast Ethernet oper- ating at 100 megabits per second). All of the twisted-pair ports support Auto-Negotiation (NWay), allowing the hub to automatically detect the speed of a network connection. This means you can connect all of your Ethernet and Fast Ethernet hosts to a DFE-908 series hub stack, without any rewiring required when a host is upgraded from 10Mbps to 100Mbps.
The DFE-908 series hubs, available in 8-port models, can be stacked with up to five hubs in a stack. A stack of five 8-port hubs gives a total of 40 Ethernet or Fast Ethernet ports. A DFE-908 series hub stack operates as a
