The ComNet™CWGE28FX4TX24MS Layer 2 Managed 28 Port Ethernet Switch supports
twenty-four(24) 10/100/1000BASE-TX portsandfour(4)1000BASE-FXports ofEthernet
data. The four 1000BASE-FX ports are SFP configurable for fiber type (multimode or
single-mode), connector type and distance. The exclusive C-Ring redundant ring
feature protects networks from interruptions or temporary malfunctions with its fast
recovery technology. The electrical ports support the 10/100/1000 Mbps Ethernet IEEE
802.3 protocol, and auto-negotiating and auto-MDI/MDIX features are included. The
CWGE28FX4TX24MS are optically (1000BASE-FX) and electrically compatible with any
IEEE 802.3 compliant Ethernet device.

Overview
Introduction
The ComNet CWGE28FX4TX24MS is a managed redundant ring Ethernet switch with
24x10/100/1000Base-(TX) ports and 4x1000Base-X SFP ports. The Ethernet Redundancy protocol,
C-Ring (Gigabit model recovery time < 30ms over 250 units of connection) and MSTP/RSTP/
STP (IEEE 802.1s/w/D) can protect your applications from network interruptions or temporary
malfunctions with its fast recovery technology.
ComNet’s Ethernet switches provide advanced IP-based bandwidth management which can limit
the maximum bandwidth for each IP device. The User can configure IP cameras and Network
Video Recorders with more bandwidth and limit other device’s bandwidth.
ComNet’s Ethernet switches also support application-based QoS. Application-based QoS can set
the highest priority for data stream according to TCP/UDP port number. The ComNet special IP
police function can permit only allowed IP address with MAC address to access the networking.
Unintended access is eliminated, as a user cannot access the IP surveillance network without
permission. Moreover, the ComNet CWGE28FX4TX24MS switch provides advanced DoS/DDoS
auto prevention. If an IP flow rises quickly, the CWGE28FX4TX24MS switch will lock the source IP
address for a certain time to prevent the attack. It is hardware-based prevention so it can prevent
DDOS attack immediately and completely. And all functions of the CWGE28FX4TX24MS can also
be centrally managed conveniently by eConsole, the Web-based interface, Telnet and console
(CLI) configuration. Therefore, the switch is one of the most reliable choices for highly managed
and Gigabit Fiber Optic Ethernet applications.

Configuration by Web Browser
This section introduces the configuration by Web browser.
About Web-based Management
An embedded HTML web site resides in flash memory on the CPU board. It contains advanced
management features and allows you to manage the switch from anywhere on the network
through a standard web browser such as Microsoft Internet Explorer.
The Web-Based Management function supports Internet Explorer 5.0 or later. It is based on Java
Applets with an aim to reduce network bandwidth consumption, enhance access speed and
present an easy viewing screen.
Note: By default, IE5.0 or later version does not allow Java Applets to open sockets. You need
to intentionaly modify the browser setting in order to enable Java Applets to use network
ports.
Preparing for Web Management
The default value is as below:
IP Address: 192.168.10.1
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.10.254
User Name: admin
Password: admin
System Login
1. Launch the browser: Internet Explorer.
2. Type http:// and the IP address of the switch. Press “Enter”.
3. The login screen appears.
4. Key in the username and password. The default username and password is “admin”.
