Chapter 1 Product Overview
1.1 Overview
Compex Managed Switch Series Compex SGX3226 is a 24-port 10/100 Mbps Fast Ethernet
SNMP Managed Switch with Integrated Router, which comes with 2 expansion slots to support
1000 Base-T Gigabit Copper Modules for uplink connection.
All 24 auto-sensing ports, which have the abilities to support full and half duplex transmission,
are on independent switching segment.
Compex SGX3226 is specially designed to support Broadband Internet sharing. Up to 4 ports
may be connected to external Cable/ADSL modem, delivering combined aggregated bandwidth
to the Internet while providing fail-over redundant link.
In summary, Compex SGX3226 should perform whenever the demands, bandwidth, reliability
and security are required.
1.2 Features and Benefits
Compex SGX3226 is specially designed for building switched network system for large
enterprise and medium to small size workgroup. More enhanced features are introduced to
Compex SGX3226, making it a perfectly high-performance backbone switch for today’s
corporate network.
1.2.1 Fast Ethernet Switching
Compex SGX3226 comes with 24 10/100 Mbps Fast Ethernet auto-sensing ports
supporting full and half duplex transmission on its 12 Gbps switching bus.
1.2.2 SNMP Management Functions
Compex SGX3226 has been designed with SNMP management functions, which has
the capability to support 4 groups of RMONS: Ethernet Statistic, History, Alarm and
Event.
1.2.3 Aggregated Router Capability
Compex SGX3226 also has the ability to support Broadband Internet sharing. Up to 4
ports may be connected to external Cable/ADSL modems, delivering combined
aggregated bandwidth to the Internet while providing fail-over redundant link.

Chapter 1 Product Overview
2
1.2.4 Port Trunking
Up to 4 ports may be defined for Port Trunking, delivering up to 800 Mbps cascading
bandwidth between two switches.
1.2.5 VLAN support and tagging
Compex SGX3226 can support up to 30 port-based VLANs and static configuration of
802.1Q VLAN tagging. It allows network administrator to separate the network into a
few segments by defining which port belong to which VLAN segment. This can
effectively control broadcast and multi-cast packet flooding the network. This not only
improvises the network performance, but also provides security between workgroups.
1.2.6 Optional Modules
Compex SGX3226 is designed with 2 expansion slots to support 3 types of optional
modules, 1000 Base-T Gigabit Fiber module, 1000 Base-SX Gigabit Fiber module and
100 Base-SC Fast Ethernet Fiber module.
1.2.7 Management Interface and capabilities
Compex SGX3226 allows you to manage the switch through common management
software. Web based management is also provided so that you do not need to have
expensive management software in order to manage your Ethernet switch. You can use
any popular Web browser software to browse the HTTP server inside Compex
SGX3226. From the Web page; you can do any configuration and statistic inquiry on
the switch. FreedomView Pro SNMP agent is also bundle together in the package.
Through the management interface, you can also change the transmission mode of all
ports on Compex SGX3226 switch. This means that you can change the operating mode
of any port to 10 Base-T half duplex, 10 Base-T full duplex, 100 Base-TX half duplex,
100 Base-TX full duplex or N-way Auto-negotiation at any time. It also means that you
can change the transmission mode through the Web browser interface, SNMP, console
port or even Telnet interface.
1.2.8 Group VLAN Registration Protocol (GVRP)
Allows automatic learning of VLANs which eliminates manual configuration of
VLANs.
1.2.9 Redundant Power Supply
RPS is constructed to prevent Compex SGX3226 from power-down if the primary
power supply is malfunctioned.
1.2.10 Spanning Tree Protocol
Provides redundant links while preventing network loops.

1.3 Applications
Compex SGX3226 may be used in the backbone with ADSL broadband connection as the access
to the Internet, as shown in Figure 1.3-1. Virtual LAN may be defined on Compex SGX3226 to
logically segmenting your LAN into multiple broadcast domains with workgroup classifications.
