24-Port Layer 2 Fast Ethernet Stackable Switch
DES-3226S
10/100Mbps L2 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.
24 10/100Mbps Ports for Workstation Connection
Switch Stacking & GBIC Port
Scalable Expansion
Flow Control to Prevent Packet Loss
The switch provides 24 10/100Mbps ports supporting auto-
sensing and auto-negotiation of network speeds and full/half
duplex. These ports can connect to workstations and print
servers, giving each a dedicated bandwidth. All ports
support auto MDI-II/MDI-X uplink, allowing you to connect
to workstations, servers, or other switches from any port
without the need to change your usual straight-through
twisted-pair cables.
The switch provides an open slot for installation of a DES-
332GS stack module, which is equipped with a stacking port
and a GBIC port. The stacking port is for switch stacking.
The GBIC port provides for flexible deployment of multi-
mode or extended cable-length single-mode fiber. At
2000Mbps full duplex, this port gives you Gigabit server
connection or attachment to a fiber backbone.
Up to 6 DES-3226S can be stacked together. You can add
units to reach maximum 144 10/100Mbps ports and 6 GBIC
ports per stack. The switches are stacked together through
high-speed stack cables that provide multi-gigabit per
second backplane, allowing the entire stack to
perform as a single entity.
The switch supports standard IEEE 802.3x Flow Control.
Working in conjunction with buffer overrun auto-detection,
this full-duplex data transfer mode provides protection
against possible data loss for 802.3x supported servers
directly connected to the switch.
Port Trunks for Aggregated Bandwidths
VLANs for Enhanced Security & Performance
Priority Queues for QoS
Flexible Transmission Scheduling
With low cost per port, port trunking provides an easy and
economical alternative solution for server connection to
attain Gigabit bandwidth. Up to 8 10/100Mbps ports or 6
Gigabit ports can be combined together to create a multi-link
load-sharing aggregated bandwidth to a server. Trunked ports
can span multiple units of the stack for fail-safe connectivity
to mission-critical servers and the network center. Up to 6
multi-link trunks can be configured for a stack.
VLANs improve security and bandwidth utilization by
limiting the broadcast domains and confining intra-group
traffic within their segments. To segment up the network,
workstations supporting IEEE 802.1Q VLAN Tagging
connected to the switch can be grouped into different Virtual
LANs (VLANs). The switch also supports GVRP (GARP
VLAN Registration Protocol) for automatic VLAN
configuration distribution.
The switch supports Layer 2 802.1p Priority Queue control.
Each packet going through the switch can be assigned a
queue priority number (in the priority bit). Packets with a
higher priority number are allowed to pass first. This
function support allows you to attach IP telephony devices or
video servers to the switch to run delay-sensitive
applications like video conference and voice over the
Internet.
The switch supports 2 methods of packet transmission
scheduling: Strict Round-Robin (SRR) and Weighted Round-
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.
