Overview
Introduction
To create reliability in your network, the ComNet CNGE8FX4TX4MS 4 10/100/1000T + 4 SFP
Managed Switch comes equipped with a proprietary redundant network protocol—X-Ring
provides users with an easy way to establish a redundant Ethernet network with ultra
high-speed recovery time less than 20ms. Also, the long MTBF (Mean Time Between Failures)
ensures that the switch will continue to operate until a Gigabit network infrastructure has
been established, without requiring any extra upgrade costs.
Aside from 4 x 10/100/1000Base-T fast Ethernet ports, the CNGE8FX4TX4MS comes
equipped with 4 SFP (mini-GBIC) ports. Traditional RJ45 ports can be used for uplinking
wide-band paths in short distance (< 100 m), while the SFP slots can be used for the
application of wideband uploading and long distance transmissions to fit the field request
flexibility. Also, the long MTBF (Mean Time Between Failures) ensures that the
CNGE8FX4TX4MS will continue to operate until a Gigabit network infrastructure has been
established, without requiring any extra upgrade costs.
SFP Advantages
The SFP fiber slots provide a lot of flexibility when planning and implementing a network. The
slot can accept any SFP-type fiber module and these modules are designed for transmitting
over distances of either 550m (multi-mode), 10km, 30km, 50km, 70km or 110km
(single-mode)—and the slot supports SFP modules for WDM single-fiber transmissions. This
means that you can easily change the transmission mode and distance of the switch by
simply pulling out the SFP module and plugging in a different module. The SFP modules are
hot-swappable and plug-and-play.
SFP with DMI (Digital Monitoring Interface) function
The ComNet™ SFP supports a digital monitoring interface (DMI) function that allows
real-time access to device operating parameters, and includes optional digital features such
2
as soft control and monitoring of SFP I/O signals. In addition, you can set up the action of
alarms and warnings by ports to manage your devices.
High-Speed Transmission
The CNGE8FX4TX4MS includes a switch controller that can automatically sense transmission
speeds (10/100/1000 Mbps). The RJ45 interface can also be auto-detected, so MDI or MDI-X
is automatically selected and a crossover cable is not required. All Ethernet ports have
memory buffers that support the store-and-forward mechanism. This assures that data is
properly transmitted.
Dual Power Input
The redundant power input design of the CNGE8FX4TX4MS is with power reserve protection
to prevent the switch from being damaged by using the wrong power source. When one of
power input has failed, the P-Fail LED will turn on and send an alarm through a relay output to
notify the user.
Flexible Mounting
The CNGE8FX4TX4MS is a compact size and can be mounted on a DIN-rail or panel. It can
be used in any location where space is scarce.
Advanced Protection
The power line of the CNGE8FX4TX4MS supports up to 3,000 VDC EFT protection, which
protects the switch from unregulated voltage and provides greater reliability. This high
voltage protection feature protects all the ports and makes the CNGE8FX4TX4MS suitable for
us in harsh industrial environments
Wide Operating Temperature
The ambient operating temperature of the CNGE8FX4TX4MS is between -40oC ~ 75oC.
3
Easy Troubleshooting
LED indicators make troubleshooting quick and easy. Each 10/100/1000 Base-TX port has 2
LEDs that display the link status and transmission speed. The three power indicators: PWR1,
PWR2 and P-Fail assist in diagnosing any problems quickly.

21
X-Ring Application
The switch supports the X-Ring protocol that can help the network recover from network
connection failure within 20ms or less, and make the network system more reliable. The
X-Ring algorithm is similar to Spanning Tree Protocol (STP) and Rapid STP (RSTP) algorithm
but its recovery time is less than STP/RSTP. The figure below is a sample of X-Ring
application.
22
Coupling Ring Application
In the network, it may be necessary to have more than one X-Ring group. By using the
coupling function it is possible to connect each X-Ring for a redundant backup. This will
ensure the transmission between two ring groups will not fail. The following figure is an
example of the coupling ring feature.
23
Note
In Dual Homing application architecture, the upper level switches must
enable Rapid Spanning Tree protocol.
Dual Homing Application
The Dual Homing function is designed to prevent a connection loss between the X-Ring
group and an upper level/core switch. By assigning two ports on the switches as Dual
Homing ports, they will become the designated backup ports in the X-Ring group. The Dual
Homing function only works when the X-Ring function is made active. Each X-Ring group can
only have one Dual Homing port.
24
Console Management
Connecting to the Console Port
The cable supplied with the switch has an RS232 connector on one end and the other end is
an RJ45 connector. Attach the end of the RS232 connector to a PC or terminal and the other
end of RJ45 connector to the console port of switch. The connected terminal or PC must
support the terminal emulation program.
