10/100Mbps L2 Stackable Switch
DES-3226S
DES-3226S with 24 10/100Mbps ports.
A DES-332GS stack module installed in the
open slot provides a GBIC port and switch
stacking capability.
24-Port Layer 2 Fast Ethernet Stackable Switch
The DES-3226S is a Stackable 10/100Mbps Layer 2 Switch designed for departmental connection. It provides 24 10/100Mbps
ports, 1 GBIC port for server or fiber backbone connection, and scalable expansion through switch stacking of up to 6 units.
Advanced features such as port trunking, VLANs and priority queues are also provided, allowing a department to
effectively deploy a bottleneck-free switching network for easy integration with a larger enterprise or campus network.
