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).
