DES-3226S
24-Port Fast Ethernet Stackable Switch
The DES-3226S is a versatile 10/100Mbps stackable Layer 2 switch designed for cost-effective departmental connections. With
24 10/100BASE-TX ports and Gigabit support, this switch blends many features typically found in more expensive chassis-
based solutions, including advanced management functions and reliable star stacking, with the price and flexibility of a
stackable.
