This section describes the functionality features of the DES-3250TG.

Fast Ethernet Technology

100Mbps Fast Ethernet (or 100BASE-T) is a standard specified by the IEEE 802.3 LAN committee. It is an extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at 100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) Ethernet protocol.

Gigabit Ethernet Technology

Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure, format, and support for full duplex and management objects, but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one hundred- fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and 100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting a company’s existing investment in hardware, software, and trained personnel.

Switch Stacking

The DES-3250TG can be used as a standalone or a stacked Switch by using the optional stacking module. Up to 12 Switches may be stacked and managed as a unit with a single IP address. Management for the entire stack is done through the Master Switch. You may add Switches later as needed. The Switch can also be grouped in a stack as a slave with the DES-3312SL Switch (acting as the Master).
