Chapter 1 Product Overview

1.1 Introduction

Compex CGX3224 is a SNMP Managed Switch with 24 10/100Mbps Fast Ethernet
ports capable of full or half duplex transmission with flow control. CGX3224 has N­Way Auto-Negotiation capability, thus allowing the ports to be automatically
configured for the highest possible operation mode between two network nodes. It
comes with 2 slots that allow insertions of 2 modular Gigabit modules or Fiber Optics
modules. Compex CGX3224 is integrated with an Aggregating Router supporting up to
4 broadband channels for Internet sharing and providing Load Balancing and Fail-Over
Redundancy to the Internet. Compex CGX3224 supports Port-based VLAN and Tagged
VLAN, improving network performance by reducing the broadcast traffic. It also
supports up to 8-level Priority Queuing, improving the performance of bandwidth­demanding applications. Compex CGX3224 is integrated with an embedded HTTP
server, providing a user-friendly web-based management interface. Compex CGX3224
is the complete solution for corporate network installation.

1.2 Features and Benefits

Compex CGX3224 is specially designed for building switched network system for large
enterprise and medium to small size workgroup. Enhanced features are introduced to
Compex CGX3224, making it a perfectly high-performance backbone switch for
today’s corporate network.

• Fast Ethernet Switching

Compex CGX3224 comes with 24 10/100 Mbps Fast Ethernet auto-sensing ports
supporting full and half duplex transmission on its 12Gbps switching bus.

• SNMP Management Functions

Compex CGX3224 has been designed with SNMP management functions, which
has the capability to support 4 groups of RMONS: Ethernet Statistic, History, Alarm
and Event.

• Aggregated Router Capability

Compex CGX3224 also has the ability to support Broadband Internet sharing. Up to
4 ports may be connected to external Cable/ADSL modems, delivering aggregated
bandwidth to the Internet while providing fail-over redundancy.

Chapter 1 Product Overview

2

• Port Trunking

Up to 4 ports may be defined for Port Trunking, delivering up to 800 Mbps
cascading bandwidth between two switches.

• VLAN Support and Tagging

Compex CGX3224 can support up to 32 port-based VLANs and static configuration
of 802.1Q VLAN tagging. It allows the network administrator to separate the
network into a few segments by defining which port belongs to which VLAN
segment. This can effectively control broadcast and multi-cast packets flooding the
network. This not only improves the network performance, but also provides
security between workgroups.

• Optional Modules

Compex CGX3224 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-FX Fast Ethernet Fiber module.

Please note that 1000 Base-LX and 100 Base-FX Single Mode modules are also
available upon request.

• Management Interface and Capabilities

Compex CGX3224 allows you to manage the switch through common management
software. Web based management is also provided so that you do not need to
purchase 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 CGX3224. From the Web page, you can do any configuration and statistic
inquiry on the switch. FreedomView Pro SNMP application is also bundled together
in the package.

Through the management interface, you can also change the transmission mode of
all ports on Compex CGX3224 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, FreedomView Pro SNMP Manager Software, console port or
even Telnet interface.

• Spanning Tree Protocol

Provides redundant links while preventing network loops.

Chapter 2 Hardware Installation

This chapter gives an overview on the hardware installation, from installing the physical cables
to resetting the device.

2.1 Physical Setup for Compex CGX3224

Compex CGX3224 is ideally suitable for office environment usage, which can be either
installed on a flat surface or mounted on a 19-inch rack. The following steps illustrate
how a proper installation is done.

2.1.1 Desktop Installation

1. Unpack Compex CGX3224.

2. Remove the backing strip from the 4 rubber feet and attach to the
underside of the switch chassis firmly.

3. Place it near a power outlet. Please put the device in the position that
would allow sufficient space for heat ventilation.

4. The surface to place Compex CGX3224 should be clean, smooth, level
and sturdy.

5. Ensure there is enough space around the unit to allow the attachment of
network cables.

6. Connect the power cord to the power socket on the rear panel of Compex
CGX3224.

2.1.2 Rack-Mounted Installation

1. Position one bracket to align with the holes on one side of Compex
CGX3224 and secure it with the smaller bracket screws (1/8-inch
diameter). Then attach the other bracket to another side of it.

2. After attaching both mounting brackets, position the device in the rack by
lining up the holes in the brackets with the appropriate holes on the rack.
Secure it to the rack using the rack-mounting screws (5/16 inches
diameters) and a screwdriver.

Chapter 2 Hardware Installation

3. Connect the power cord to the power socket on the rear panel of Compex
CGX3224.

NOTE

For proper ventilation, do allow about 4 inches of clearance on the front and back
of the switch. This is especially important in an enclosed rack.

2.1.3 Expansion Module Installation

A series of optional expansion modules are available for Compex CGX3224
to upgrades its features. Please note that Compex CGX3224 is not shipped
with the Gigabit modules.

1. Power off the switch. Insert the module carefully into the expansion
module window and push it along the module rail until it stops. Ensure
that there is a secure connection to the PCB Board of Compex CGX3224.

2. Tighten the screws on the module.

2.1.4 Removing the Expansion Module

1. Power off the switch.

2. Disconnect any cable from the module.

3. Unscrew and pull out the module slowly from the expansion module slot.

4. Slide the module completely out of the chassis and cover the window with
the cover plates, fasten back using the original screws.

5.2 Virtual Local Area Network (VLAN) Configuration

Compex CGX3224 supports Virtual LAN, which logically groups every connection into
VLANs for traffic isolation and security purposes. Both tagged and untagged based
VLAN are supported with a total maximum of 32 groups. Each VLAN group only
forwards traffic within its member ports. For tagged VLAN, each port can be a member
of more than one VLAN group and it also supports eight levels of priority. You can also
create a Tagged VLAN and support a connection with a legacy untagged VLAN. The
VLAN configuration feature also allows you to build, delete, view tagged/untagged
VLAN groups and set priority for tagged VLANs. The range of VID starts from 2 to

4091. VID 001 is the default for Group 1.

Procedures

1. Go to VLAN Config from the Command window.

2. Decide which Group you want to set for monitoring using mirror port. Click status
column for that particular group and key in the VLAN ID.

3. Next, click on the dashed line ‘–’ to select either ‘T’ for Tagged or ‘U’ for
Untagged.

4. Hit on Apply button after you are satisfied with the setup. Click Save button to
update the configuration.
