CWGE2FE24MODMS
MODULAR 26 PORT MANAGED ETHERNET SWITCH WITH UP TO
24-PORT 10/100T(X) OR 100FX AND 2-PORT 10/100/1000T(X) OR 1000FX
V1.03 – May 2011
The ComNet™ CWGE2FE24MODMS Managed Ethernet Switch chassis provides up to twenty-six ports of Ethernet
connectivity through the use of three eight-port expansion modules and two rear-mounted fixed combo ports. This
Ethernet switch is easily configurable by selecting, sold separately, eight port modules that allow for all copper, or
all optical with SFP modules making the CWGE2FE24MODMS switch available for use with either conventional UTP
copper or fiber media. The twenty-four modular ports support the 10/100 Mbps electrical or 100Mbps optical
Ethernet IEEE 802.3 protocol. Auto-negotiating and auto-MDI/MDIX features are provided for simplicity and ease of
installation on electrical ports. Two additional ports are Gigabit combo SFP ports. These network managed layer 2
switches are optically and electrically compatible with IEEE 802.3 compliant Ethernet devices. Plug-and-play
design ensures ease of installation, and no electrical or optical adjustments are ever required. The
CWGE2FE24MODMS incorporates LED indicators for monitoring the operating status of the managed switchand
network. These units are rack mountable. The CWGE2FE24MODMS and its corresponding modules are designed
for installation in benign (0º – +45º C) operating environments.

1. Introduction
The CWGE2FE24MODMS 26 Port Combo Managed Switch is a modular switch that can
be used to build high-performance switched workgroup networks. This switch is a
store-and-forward device that offers low latency for high-speed networking. The Switch is
targeted at workgroup, department or backbone computing environments.
The CWGE2FE24MODMS 26 Port Combo Managed Switch features a “store-and-forward”
switching scheme. This allows the switch to auto-learn and store source Address in an
8K-entry MAC Address table.
MDI (Medium Dependent Interface) Port is also called an "uplink port". The MDI port does
not cross transmit and receive lines that is done by the regular ports (MDI-X ports) that
connect to the end stations. 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.
The CWGE2FE24MODMS 26 Port Combo Managed Switch has 3-module slots. The user
can purchase the modules in accordance with their needs that give flexibility on network
applications.

Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the usable total bandwidth of a
network, eliminated congestion problems inherent with CSMA/CD (Carrier Sense multIP
Address le access with Collision Detection) protocol, and greatly reduced unnecessary
transmission.
This revolutionized networking. First, by allowing two-way simultaneous transmission over
the same port (Full-duplex), it essentially doubled the bandwidth. Second, by reducing the
collision domain to a single switch-port 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 eliminated unnecessary transmission that slows 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 any loss of data. Auto-negotiation and flow-control may require
disablement for some networking operations involving legacy equipment. Disabling the
auto-negotiation is accomplished by fixing the speed or duplex operation of a port.
Ethernet Switching Technology supplied higher performance at costs lower than other
solutions. Wider bandwidth, no congestion, and the reduction in traffic is why switching is
replacing expensive routers and inefficient hubs as the ultimate networking solution.
Switching brought a whole new way of thinking to networking.

2. Hardware Description
This section describes the hardware of the CWGE2FE24MODMS switch, and gives a
physical and functional overview of the switch.
PhysicalDimension
The CWGE2FE24MODMS switch has a physical dimension of 440mm(W) x 280mm(D) x
44mm(H).
FrontPanel
The Front Panel of the CWGE2FE24MODMS switch supports 2 kinds of port modules.
Please refer to the module user guide for further information.

8
LEDIndicators
Accompanying the Copper/SFP combo ports, four LED indicators are located on the rear
panel beside each combo port. The LEDs indicate the status of Link/Activity,
Full-Duplex/Collision, and transmission speed for the respective ports. The table below
gives definition for each LED indicator.
LED Status Description
Green The port is connecting with the device.
Blinks The port is receiving or transmitting data.
LK/ACT
Off No device attached.
Yellow The port is operating in Full-duplex mode.
Blinks Collision of Packets occurs in the port.
FD/COL
Off In half-duplex mode
1000 Green The port is operating at the speed of 1000Mbps
100 Green The port is operating at the speed of 100Mbps (for RJ-45 port only)

RearPanel
The 3-pronged power plug, 2 fans, DC power input, 2 Gigabit Copper/SFP combo port,
and one RS-232 console port are located at the rear Panel of the CWGE2FE24MODMS
switch as shown in Figure 2-1. The Switch will work with AC power in the range of
100-240V AC, 50-60Hz.
The Rear Panel of the CWGE2FE24MODMS switch

10
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 allow
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.

11
Rack-mounted Installation
The CWGE2FE24MODMS switch comes with a rack-mounted kit and can be mounted in
an EIA standard size, 19-inch Rack. The switch can be placed in a wiring closet with other
equipment.
Perform the following steps to rack mount the switch:
A. Position one bracket to align with the holes on one side of the switch and secure it
with the smaller bracket screws. Then attach the remaining bracket to the other side
of the switch.
Attach mounting brackets with screws
B. After attaching both mounting brackets, position the switch in the rack by lining up the
holes in the brackets with the appropriate holes on the rack. Secure the switch to the
rack with a screwdriver and the rack-mounting screws.
Mount the Switch in 19” Rack

12
Note: For proper ventilation, allow about at least 4 inches (10 cm) of clearance on the
front and 3.4 inches (8 cm) on the back of the switch. This is especially important for
enclosed rack installation.
PowerOn
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 of the switch
works with voltage range of AC in the 100-240VAC, frequency 50~60Hz. Check the power
indicator on the front panel to see if power is properly supplied.

3. Network Application
This section provides you a few samples of network topology in which the switch is used.
In general, the CWGE2FE24MODMS switch is designed as a segment switch. That is,
with its large Address table (8000 MAC Address) and high performance, it is ideal for
interconnecting networking segments.
Personal computers, workstations and servers can communicate each other by directly
connecting with CWGE2FE24MODMS switch. The switch automatically learns nodes
Addresses, that are subsequently used to filter and forward all traffic based on the
destination Address.
By using the Gigabit copper/SFP combo port (on the rear side of the switch), 10/100Mbps
copper, or Ethernet Fiber port the switch can connect with another switch or hub to
interconnect other small-switched workgroups to form a larger switched network.
Meanwhile, you can also use Ethernet or fiber ports to connect switches. The following
figure is an example of the CWGE2FE24MODMS switch application topology.
The example of application topology

14
ConnectingtotheSwitch
The Console port is a female DB-9 connector that enables a connection to a PC or
terminal for monitoring and configuring the Switch. Use the supplied RS-232 cable with a
male DB-9 connector to connect a terminal or PC to the Console port.
The Console configuration (out of band) allows you to set the switch for remote terminal
as if the console terminal were directly connected to it.
