Introduction; Features; Ports; Performance Features - D-Link DES-3250TG User Manual

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

Features

The DES-3250TG Switch was designed for easy installation and high performance in an environment
where traffic on the network and the number of users increase continuously.
Switch features include:

Ports

•
Forty-eight high-performance NWay ports all operating at 10/100 Mbps for connecting to end
stations, servers and hubs.
•
All 48 10/100 UTP ports can auto-negotiate (NWay) between 10Mbps/100Mbps, half-duplex or
full duplex.
•
One front panel slide-in module interface for a 2-port 1000BASE-T module (provided) and one
front panel slide-in module interface for a 2-port Mini GBIC Gigabit Ethernet module (optional).
Please note that although these two front panel modules can be used simultaneously, the ports
must be different. For example, if port 49x is used on the Mini GBIC module, port 49x is not
available on the 1000BASE-T module, and vice versa.
•
RS-232 DCE Diagnostic port (console port) for setting up and managing the Switch via a
connection to a console terminal or PC using a terminal emulation program.

Performance Features

•
Store and forward switching scheme.
•
Full and half-duplex for both 10Mbps and 100Mbps connections. The front-port Gigabit Ethernet
module operates at full duplex only. Full duplex allows the switch port to simultaneously
transmit and receive data, and only works with connections to full-duplex capable end stations
and switches. Connections to hubs must take place at half-duplex.
•
Auto-polarity detection and correction of incorrect polarity on the transmit and receive twisted-
pair at each port.
•
IEEE 802.3z compliant for Mini GBIC ports (optional module).
