CWFE8TX8MS
COMMERCIAL GRADE 8 PORT MANAGED
ETHERNET SWITCH WITH (8) 10/100TX PORTS
V1.0 – September 2010
The ComNet CWFE8TX8MS Managed Ethernet Switch provides transmission of 100 BASE-TX Ethernet
data. These units are available for use with conventional CAT-5e copper transmission media. Eight
electrical ports are available for easily implementing point-to-point, linear add-drop, drop-and-repeat,
star or true self-healing ring and mesh network system architectures. The electrical ports support the
10/100 Mbps (100 BASE-TX) Ethernet IEEE 802.3 protocol, auto-negotiating and auto-MDI/MDIX features
are provided for simplicity and ease of installation. Plug-and-play design ensures ease of installation, and
no electrical adjustments are ever required. The CWFE8TX8MS incorporates LED indicators for
monitoring the operating status of the managed switch and network.

Introduction
The CWFE8TX8MS Managed Ethernet Switch is a compact size switch that is
an ideal solution for industrial applications. It provides a Fast Ethernet
switching function that allows for high-performance, low-cost network
performance. The CWFE8TX8MS features a store-and-forward switching and
can auto-learn and store source addresses on an 8K-entry MAC address
table.
The CWFE8TX8MS provides 8 switched auto-sensing 10/100 Mbps RJ45
Ethernet ports. The switch will automatically detect the speed of the device
that you plug into it to allow you to use both 10 and 100Mbps devices. The
10Mbps bandwidth will accommodate 10Mbps workgroup hubs while
simultaneously providing the 100Mbps bandwidth needed to accommodate
multimedia applications. In addition, each RJ45 port supports the Auto
MDI/MDIX function.
With built-in web-based management, managing and configuring the
CWFE8TX8MS becomes easier. The user can visually configure and manage
the network via Web Browser. Just click the mouse instead of typing
command strings. However, the CWFE8TX8MS can also be managed via
Telnet, Console, or SNMP Management.

Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with Carrier Sense multiple
access with Collision Detection (CSMA/CD) protocol, and greatly reduced
unnecessary transmission.
This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the
store-and-forward technology’s approach of inspecting each packet to
intercept corrupt or redundant data, switching eliminated unnecessary
transmission that slow the network. By employing address-learning, it
replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex operation of each port,
based on the capability of both devices. Flow-control allows transmission
from a 100Mbps node to a 10Mbps node without loss of data.
Auto-negotiation and flow-control may require disablement for some
networking operations that involve legacy equipment. Disabling the
auto-negotiation is accomplished by adjusting the speed or duplex operation
of a port.
Ethernet Switching Technology supplies higher performance at costs lower
than other solutions. Wider bandwidth, no congestion, and the reduction in
network traffic is why the use of an Ethernet switch is replacing expensive
routers and inefficient hubs as the best network solution.

Management Methods
The CWFE8TX8MS supports following management methods:
Console and Telnet Management
Web-based Management
SNMP Network Management
Console and Telnet Management
Console Management is done through the RS-232 Console Port. Managing
the CWFE8TX8MS by this method requires a direct connection between PC
and the CWFE8TX8MS Switch. While Telnet management is done over the
network. Once the CWFE8TX8MS is on the network, you can use Telnet to
Log in and change the configuration.
Web-based Management
The switch provides an embedded HTML web site residing in flash memory. It
offers advanced management features and allows users to manage the
CWFE8TX8MS from anywhere on the network through a standard browser
such as Microsoft Internet Explorer.
SNMP Network Management
SNMP (Simple Network Management Protocol) provides a means to monitor
and control network devices, and to manage configurations, statistic
collection, performance, and security.

Hardware Description
The CWFE8TX8MS is a compact switch (10 inches) with eight auto-sensing
10/100Mbps Ethernet RJ45 ports.
The physical dimensions of the CWFE8TX8MS are: 250mmx 132mmx
37mm (Lx Wx H)
Front Panel
The Front Panel of the CWFE8TX8MSseries consist of eight auto-sensing
10/100Mbps Ethernet RJ45 ports (automatic MDI/MDIX), and the LED
indicators are also located on the front panel of the switch.
Figure 2-1. The Front Panel of the CWFE8TX8MS
RJ45 Ports (Auto MDI/MDIX): Eight 10/100 auto-sensing for 10Base-T
or 100Base-TX connections.
[In general, MDI means connecting to another Hub or Switch while MDIX
means connecting to a workstation or PC. Therefore, Auto MDI/MDIX
means that you can connect to another Switch or workstation without
changing to non-crossover or crossover cabling.]

Rear Panel
The Console port and 3-pronged power plug are located at the rear panel of
the CWFE8TX8MS as shown in Figure 2-8. The CWFE8TX8MS will work with
current in the range 100-240V AC, 50-60Hz.
Figure 2-7 The Rear Panel of the 8TP Management Switch
Console Port: Console management can be done through the Console Port.
It requires a direct connection between the switch and an end station (PC) via
a RS-232 cable.
13
Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby.
Make sure there is enough clearance around the switch to allow attachment of
cables, power cord and air circulation.
Attaching Rubber Feet
A. Make sure mounting surface on the bottom of the Switch is grease and
dust free.
B. Remove adhesive backing from your rubber feet.
C. Apply the rubber feet to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.
Figure 2-8. Attaching Rubber Feet to each corner on the bottom of the switch
14
Power On
Connect the power cord to the power socket on the rear panel of the switch.
The other side of power cord connects to the power outlet. The internal power
supply in the switch works in the voltage range 100-240VAC, frequency
50~60Hz.
Check the power indicator on the front panel to see if power is properly
supplied.
15
Network Application
This section provides you a few samples of network topology in which the
Switch is used. In general, the CWFE8TX8MS can be used as a desktop or
segment switch.
Desktop Application
The CWFE8TX8MS is designed to be a desktop-sized switch that is an ideal
solution for small workgroup. The switch can be used as a standalone switch
that computers, servers, print-servers are directly connected to form a small
workgroup.
Figure 3-1. Desktop Application
16
Segment Application
For enterprise networks where large data broadcasts are constantly
processed, this switch is suitable for a department to connect to the corporate
backbone.
Figure 3-2 Segment Applications
17
Network Configuration
This section explains how to configure the console management via a direct
connection to the console port of the CWFE8TX8MS.
Console management involves the administration of the switch via a direct
connection to the RS-232 console port. This port is a female DB-9 connector.
From the main menu of the console program, the user has access to manage
the functions of the switch.
Connecting a Terminal or PC to the Console Port
Figure 4-1. Connecting the CWFE8TX8MS to a terminal via RS-232 cable
Use the supplied RS-232 cable to connect a terminal or PC to the console
port. The terminal or PC to be connected must support the terminal emulation
program.
After the connection between the switch and PC is finished, turn on the PC
and run a terminal emulation program or Hyper Terminal to match the
following default characteristics of the console port:
18
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
Control flow: None
