INTRODUCTION
This chapter introduces the D-Link DES-2212 switch, and the technologies that it uses to give you improved network performance and reliability.
DES-2212 Ethernet/Fast Ethernet Switch
The DES-2212 is an Ethernet/Fast Ethernet switch for networks needing improved performance, the ability to interconnect between 10Mbps and 100Mbps Ethernet networks, and SNMP network management capability.
Ports
The DES-2212 has twelve ports, four NWay 10BASE-TX Ethernet/100BASE-TX Fast Ethernet ports, and eight 10BASE-T twisted- pair Ethernet ports. Among the Fast Ethernet ports, one of the ports can also use an industry-standard MII connector, making it possible to interface to different types of 100BASE-X Fast Ethernet network media, such as 100BASE-FX fiber optic cable or 100BASE-T4 twisted pair.
Another of the 100BASE-TX ports can optionally serve as an uplink port, making it possible to connect the port to a Fast Ethernet hub without using a crossover cable.
