Product Overview
This section contains an overview and technical specifications of the D-Link DES-3226L
switch.
The D-Link DES-3226L is a high-performance Fast Ethernet switch that provides 24 10/100
Mbps switched ports with two combo gigabit copper/Small Form Factor Pluggable (SFP)
ports. The switched 10/100 Mbps ports are ideal for segmenting networks into small,
connected sub networks for superior performance, enabling the most demanding multimedia
and imaging applications over the network. The two fixed-in gigabit copper ports support 10/
100/1000BASE-T speed. There are also two SFP ports that provide optional fiber gigabit
uplinks. These SFP ports are associated with the gigabit copper ports, so that if the SFP ports
are used, the gigabit copper ports are disabled.
