This chapter introduces the D-Link DES-2218 switch, and the technologies
that it uses to give you improved network performance and reliability.
DES-2218 Ethernet/Fast Ethernet
Switch
The DES-2218 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-2218 has eighteen ports, two NWay 10BASE-TX
Ethernet/100BASE-TX Fast Ethernet ports, and sixteen 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.
The other 10BASE-T/100BASE-TX port can optionally serve as an uplink
port, making it possible to connect the port to an Ethernet or Fast Ethernet
hub without using a crossover cable.
