auto-negotiating and auto-MDI/MDIX features are provided for simplicity and ease of installation. Ports 8 – 9
are 10/100/1000 configurable for copper or 1000 fiber media for use with multimode or single mode optical
fiber without need for configuration, selected by optional SFP modules. These network managed layer 2
switches are optically and electrically compatible with any IEEE 802.3 compliant Ethernet devices.
Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required.
The CWGE9MS incorporates LED indicators for monitoring the operating status of the managed switch and
network.

Chapter 2 Hardware Description
This section describes the hardware of the CWGE9MS managed Ethernet switch.
2.1 Physical Dimension
The physical dimensions of the CWGE9MS managed Ethernet switch is 217mm(W) x
140mm(D) x 43mm(H)
2.2 Front Panel
The front panel of the CWGE9MS managed Ethernet switch consists of 7x auto-sensing
10/100/1000Mbps Ethernet RJ45 ports (automatic MDI/MDIX), 2 SFP/Giga copper
combo ports, and the LED indicators are also located on the front panel of the switch.
Front Panel of the 7 10/100/1000TX + 2 10/100/1000T and 1000 SFP Combo Managed Switch
RJ45 Ports (Auto MDI/MDIX)
There are 7 10/100/1000 auto-sensing RJ45 ports for 10Base-T, 100Base-TX,or
1000Base-T 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 non-crossover or
crossover cabling.

12
2 SFP/Giga copper combo port
Traditional RJ45 ports can be used for unlinking wide-band paths in short distance
(<100m), or the appropriate replaceable mini-GBIC ports can be used for the application
of wideband unlinking and long distance transmissions to fit the flexible field request.
2.3 Rear Panel
The 3-pronged power plug are located at the rear panel of the CWGE9MS managed
Ethernet switch as shown in figure. The switch will work with AC in the range 100-240V
AC, 50-60Hz.

Chapter 3 Hardware Installation
3.1 Desktop Installation
Set the switch on a sufficiently large flat space with a power outlet nearby. The surface
where you put your Switch should be clean, smooth, level, and sturdy. Make sure there
is enough clearance around the Switch to allow attachment of cables, power cord and air
circulation.
3.2 Attaching Rubber Feet
1. Make sure mounting surface on the bottom of the switch is grease and dust free.
2. Remove adhesive backing from your rubber feet.
3. Apply the rubber feet to each corner on the bottom of the switch. These footpads
can prevent the switch from shock/vibration.
3.3 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 works with AC in the
voltage range 90-240VAC, frequency 50~60Hz. Check the power indicator on the front
panel to see if power is properly supplied.

15
Chapter 4 Network Application
This section provides you a few samples of network topology in which the switch is used.
In general, the CWGE9MS managed Ethernet switch is designed to be used as a
desktop or segment switch.
4.1 Desktop Application
The CWGE9MS managed Ethernet switch is designed to be a desktop size switch that is
an ideal solution for small workgroup. The switch can be used as a standalone switch to
which personal computers, server, printer server are directly connected to form small
workgroup.
4.2 Segment Application
For enterprise networks where large data broadcast are constantly processed, this
switch is suitable for department user to connect to the corporate backbone.

16
You can use the CWGE9MS managed Ethernet switch to connect PCs, workstations,
and servers to each other by connecting these devices directly to the switch. All the
devices in this network can communicate with each other. Connecting servers to the
backbone switch allow other users to access the server’s data.
The switch automatically learns node address, which are subsequently used to filter and
forward all traffic based on the destination address. You can use any of the RJ45 port of
the CWGE9MS managed Ethernet switch to connect with another Switch or Hub to
interconnect each of your small-switched workgroups to form a larger switched network.
4.3 X-Ring Application
This industrial switch supports the X-Ring protocol that can help the network system to
recovery from network connection failure within 300ms, making the network system more
reliable. The X-Ring algorithm is similar to spanning tree protocol (STP) algorithm but the
recovery time is faster than STP. The following figure is a sample X-Ring configuration.

17
[NOTE]
When the X-Ring function is enabled, the user must disable the RSTP. The X-Ring
function and RSTP function cannot operate simultaneously.
With X-Ring topology, every switch enables the X-Ring function and assigns two
member ports in the ring. Only one switch in the X-Ring group would be the backup switch
with one of the two member ports’ being a backup port then switches are called working
switches’ working ports. When the network connection fails, the backup port will
automatically become a working port to the failure. In the X-Ring group, switches are
setting in “slave mode” by default, but one must be the “master mode”. If there are 2 or
more switches in the master mode, then software will automatically select the switch with
lowest MAC address number as the ring master. The ringmaster has the rights to
negotiate and command to other switches in the X-Ring group.
If a link fails the ringmaster is alerted and invokes its secondary port to rebuild the

18
network detection of the failed link’s activation of the master’s backup link and address
table. If the failed link is restored, the ring slaves will alert the ringmaster to restore
normal operation by disabling the backup link on the network in less than 300ms.
4.4 Coupling Ring Application
Within the network there may be more than one X-Ring group. By using the coupling ring
function, it can connect each X-Ring for redundant backup. It can ensure the transmission
between two ring groups will not fail. The following figure is a sample of a coupling ring
application. The couple ring consists of four switches—switch 1 through switch 4 that are
connected to each other via the paths in red. Please note that the Coupling Ring Backup Path
between switch 1 and switch 3 is blocked; it will work only when the path between switch 2 and
switch 4 is broken or disconnected.
4.5 Dual Homing Application
It provides the connection loss from between X-Ring group and an upper level/core
switch. Assign two ports to be the Dual Homing port that is backup port in the X-Ring
group. The Dual Homing function only works when the X-Ring function is active. Each
X-Ring group only has one Dual Homing port.
