CNGE2FE24MSPOE
ENVIRONMENTALLY HARDENED MANAGED
ETHERNET SWITCH WITH (24) 10/100TX
+ (2) 10/100/1000FX RJ45 or 1000FX SFP PORTS
V1.02 – October 2009
The ComNet™ CNGE2FE24MSPoE Managed Ethernet Switch provides transmission of (24) 10/100 BASE-
TX and (2) 10/100/1000TX or 1000FX combo ports. Unlike most Ethernet switches, these environmentally
hardened units are designed for deployment in difficult operating environments, and are available for use
with either conventional CAT-5e copper or optical transmission media. The 24 electrical ports support the
10/100 Mbps Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/MDIX features are
provided for simplicity and ease of installation. All 24 ports support IEEE.802.3af based POE. 2 ports are
10/100/1000 configurable for copper or fiber media for use with multimode or single mode optical fiber,
selected by optional SFP modules. These network managed layer 2 switches are optically (1000 BASE-
FX) 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
CNGE2FE24MSPoE incorporates LED indicators for monitoring the operating status of the managed
switch and network. These units are rack mountable.

digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses, and can radiate radio frequency
energy. It may cause harmful interference to radio communications if this
equipment is not installed and used in accordance with the instructions. However,
there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
CE Mark Warning
This is a Class-A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.

2.5 Cabling
Use four twisted-pair, Category 5e or above cabling for RJ45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must be
less than 100 meters (328 ft.) long.
Use fiber optic cabling and connectors which are suitable for the selected SFP fiber
module installed. The maximum transmission distance will be determined by the
selected SFP module.
To connect the SFP transceiver using LC connectors, please follow the steps shown below:
First, insert the transceiver into the SFP module. Notice that the triangle mark is the bottom
of the module.

To remove the LC connector from the transceiver, please follow the steps shown below:
First, press the upper side of the LC connector to release from the transceiver and pull it out.
Remove LC connector
Second, push down the metal loop and pull the transceiver out by the plastic handle.
Pull out from the transceiver
21
2.6 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.
2.6.1 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
help prevent shock/vibration.
Attaching Rubber Feet to each corner on the bottom of the Switch
2.7 Rack-mounted Installation
The Switch comes with a rack-mounted kit and can be mounted in an EIA standard size,
19-inch Rack. It can be placed in a wiring closet with other equipment.
22
Perform the following steps to rack-mount the switch:
A. Position one plate to align with the holes on one side of the hub and secure it with the
smaller plate screws. Then, attach the remaining plate to the other side of the switch.
Attach mounting plates with screws
B. After attaching both mounting plates, position the switch in the rack by lining up the
holes in the plates with the appropriate holes on the rack. Secure the switch to the rack
with a screwdriver and suitable rack-mounting screws.
Mount the Switch in an EIA standard 19-inch Rack
Note: For proper ventilation, allow 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.
23
3 Network Application
This segment provides samples to help the user understand industrial switch applications.
For sample applications of the industrial switch, see the figures below.
24
3.1 X-Ring Application
The industrial switch supports the X-Ring protocol that can help the network system to
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 an X-Ring application.
25
3.2 Couple Ring Application
In the network, it may have more than one X-Ring group. Using the coupling ring function
can connect each X-Ring for redundant backup. It can ensure the transmissions between
two ring groups do not fail. The following figure is a sample of coupling ring application.
26
3.3 Central Ring Application
Central Ring is an advanced function which supports backup connection for redundant
transmission. When the connection fails, the system will recover from failure within 20
milliseconds. Central Ring can also handle up to 4 rings by configuring a single switch only
as the ring master switch.
27
3.4 Dual Homing Application
Dual Homing function is to prevent a connection loss between X-Ring group(s) and upper
level/core switches. Assign one port to be the Dual Homing port that is the 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.
[NOTE] In Dual Homing application architecture, the upper level switches need to enable
the Rapid Spanning Tree protocol.
28
4 Console Management
4.1 Connecting to the Console Port
Use the supplied RS-232 cable to connect between a terminal/PC and the console port.
The terminal or PC being connected to must support the terminal emulation program.
Connecting the switch to a terminal via RS-232 cable
4.2 Login in the Console Interface
When the connection between Switch and PC is ready, turn on the PC and run a terminal
emulation program or Hyper Terminal and configure its communication parameters to
match the following default characteristics of the console port:
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
Stop Bit: 1
29
Flow control: None
The settings of communication parameters
After finishing the parameter settings, select ‘OK’. When the blank screen shows up, press
Enter key to bring out the login prompt. Key in ‘admin’ (default value) for both User name
and Password (use Enter key to switch), then press Enter key and the Main Menu of
console management appears.
