“Quick Install Guide”
Compex 24 - Port All 10/100 Management Switch
(SGX3224, SGX3224 PLUS)
Introduction
Compex SGX3224 is an all 10/100 24-port Management Ethernet Switch.
Compex SGX3224 PLUS has all the functions of SGX3224 plus one additional
1000Base-SX Gigabit Ethernet port for Uplink connection. All the 24 10/100
ports are on independent switching segment with full duplex capability, and this
provides up to 4.8 Gbps bandwidth for the 10/100 connections. Uplink switch is
provided on one of the ports so that you can use a normal straight through cable
for connecting two switches. SGX3224 PLUS with the gigabit connection
supports the Multi-mode fiber for 200m. All ports, including Gigabit port
(SGX3224 PLUS), support full duplex operation, which allows bandwidth to be
doubled for every port. Furthermore, port 1 is a shared port on which user can
insert a fiber optic module for 100Base-FX connection; after this 100Base-FX
fiber module is inserted, RJ-45 UTP port 1 will be disabled.

♦10Base-T/100Base-TX N-Way Auto-Negotiation
In the SGX3224, all ports use the N-Way auto-negotiation mechanism
to detect the speed of the attached network adapter. This feature gives
users the freedom and convenience of connecting the switch to a
10Base-T or 100Base-TX network without doing any manual
configuration and setup.
♦10/100 Mbps Switching Hub
A cost-effective 100Mbps and 10Mbps switching function in single
unit. Divides a network into smaller shared groups, eliminating
unnecessary traffic, multiplying available bandwidth, and relieving
congestion on server paths.
♦10/100 Mbps Integration
24 high-speed ports permit Ethernet workgroups to communicate with
Fast Ethernet users in a single integrated network, and share servers
connected to the dedicated 100Mbps ports. Port expansion is easy by
connecting several switches and hubs together through uplink port.
♦Linking Up 10Base-T and 100Base-TX Technology

4Compex 24 - Port All 10/100 Management Switch
(SGX3224, SGX3224 PLUS) English
One-time migration from 10Base-T to 100Base-TX technology can be
very costly. The SGX3224 addresses this problem by allowing existing
10Base-T networks to communicate with 100Base-TX networks.
Performance does not degrade as each 10Base-T/100Base-TX segment
continues to operate at its own speed. Enterprise networks can thus be
progressively upgraded and older segments gradually phased out
without sacrificing interconnectivity or performance.
♦Half or Full Duplex Support
Users can opt for the Full Duplex mode to double the dedicated
bandwidth.
♦Management capability:
SGX3224 10/100 Management Ethernet Switch also gets SNMP,
RMON management capability. It allows you to manage the switch
through common management software. Furthermore, it supports four
groups of RMON MIB that will give you extensive management
capability. Web base management is also provided so that you do not
need to have expensive management software in order to manage your
SGX3224 switch. You can use any popular Web browser software to
browse the HTTP server inside SGX3224 switch and, from the Web
page; you can do any configuration and statistic inquiry on the switch.
SGX3224 also support Port VLAN function. 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
boardcast and multi-cast packet flooding the network.
Through the management interface, user can also change the
transmission mode of all ports on SGX3224 switch. This means that
you can change the operating mode of any port to 10Base-T half duplex,
10Base-T full duplex, 100Base-TX half duplex, 100Base-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.

Advance Management Functions Setup Procedures:
In this section, the procedure of setting up the following functions would be
discussed:
1. Transmission mode of each port;
2. Port VLAN set up;
3. Viewing of basic statistics;
4. Saving of current configuration;
5. Restoring default configuration;
Since all the above functions are being set up through management interface
(either Web Browser Interface or Command Line Interface), we need a PC with
TCP/IP protocol so that it can run a Web browser program like IE4 or Netscape
4. Furthermore, in order to communicate with SGX3224, you need to set up the
IP address of SGX3224 through the following means:
1. Default IP address
Just use the default IP address; default IP address is 192.168.168.99 with
subnet mask 255.255.255.0 and default gateway 192.168.168.1.
2. BootP Server
BootP server that can assign IP address, SGX3224 will automatically look
for a BootP server during power up and get a valid IP address. Consult your
BootP server document on how to set up IP address for SGX3224.
3. Command Line Interface
Using Command Line Interface to set up the IP address; in Command Line
Interface, there is a command “set ip address xxx.xxx.xxx.xxx
yyy.yyy.yyy.yyy” where x is the new IP address and y being the subnet
mask. The detail procedures are:
a) You need a PC with one free COM port (COM1 or COM2); this PC
must be running Windows95 or Windows98. Run the HyperTerminal

10 Compex 24 - Port All 10/100 Management Switch
(SGX3224, SGX3224 PLUS) English
program with “Direct to COMx” and date rate is 19200, 8-bit data bit,
no parity and 1 stop bit.
b) Connect the PC free COM port to SGX3224 RS232 connector at the
back of the case with the null modem cable provided.
c) Turn on SGX3224 and you will see message “System Ready” after a
short while (around 15 to 20 seconds).
d) Press “Enter” key on the PC and you will see message “Access
granted” message. If you have used the Command Line Interface or
Web Browser Interface before and you have set the SGX3224 with
login password, there will be a login prompt asking for password after
you press “Enter” key. Just key in the password and “Access granted”
message will appear.
e) Type “set ip address xxx.xxx.xxx.xxx” where x is desired IP address.
