CNGE24MS(M,S)2-OB
INDUSTRIAL 24-PORT ALL GIGABIT MANAGED ETHERNET SWITCH
WITH 16 TX PORTS AND 8 SFP PORTS PLUS OPTICAL BYPASS
The ComNet CNGE24MS-OB is a Managed Ethernet Switch with sixteen
10/100/1000 Mbps TX ports and eight 100/1000 Mbps SFP* ports that use
ComNet SFPs for fiber type, connector type and distance. This switch also
includes two sets of bypass ports that ensure network integrity during power
loss or maintenance. The CNGE24MS-OB is IEEE802.3-compliant and offers
multiple Ethernet redundancy protocols (ComRing, C-Ring, and MSTP/RSTP/
STP) which protect your applications from network interruptions or temporary
malfunctions by redirecting transmission within the network. 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.

Rack-mount Installation
The device comes with two mounting kits for you to install the device to a rack. Before installation,
keep the following guidelines in mind.
Elevated Operating Ambient: If installed in a closed environment, make sure the operating
ambient temperature is compatible with the maximum ambient temperature (Tma) specified by
the manufacturer.
Reduced Air Flow: Make sure the amount of air flow required for safe operation of the equipment
is not compromised during installation.
Mechanical Loading: Make sure the mounting of the equipment is not in a hazardous condition
due to uneven mechanical loading.
Circuit Overloading: Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of the circuits might have on overcurrent protection
and supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Follow the steps below to install the device to a rack.
Step 1: Install the L-shape mounting kits provided in the package to the left and right of the
device.
Step 2: With front brackets orientated in front of the rack, mount the device in the rack with four
rack-mounting screws.

Wiring
WARNING: Do not disconnect modules or wires unless power has been switched off or the area
is known to be non-hazardous. The devices may only be connected to the supply voltage shown
on the type plate.
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your switches.
2. Calculate the maximum possible current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious
damage to your equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire conduit.
To avoid interference, wires with different signal characteristics should be routed separately.
6. You can use the type of signal transmitted through a wire to determine which wires should be
kept separate. The rule of thumb is that wiring sharing similar electrical characteristics can be
bundled together
7. You should separate input wiring from output wiring
8. It is advised to label the wiring to all devices in the system

Fault Relay
The relay contacts of the 4-pin terminal block connector are used to detect user-configured
events. The two wires attached to the fault contacts form an open circuit when a user-configured
when an event is triggered. If a user-configured event does not occur, the fault circuit remains
closed.
AC Power Connection
For power supply, simply insert the AC power cable to the power connector at the back of the
switch and turn on the power switch. The input voltage is 100V~240V / 50~60Hz.

Ethernet Cables
The CNGE24MS(M,S)2-OB switch has standard Ethernet ports. According to the link type, the

SFP
The switch has fiber optic ports with SFP connectors. The fiber optical ports are available with
multi-mode and single-mode fiber with various distance and connector types. Please remember
that the TX port of Switch A should be connected to the RX port of Switch B.

Bypass Ports
When a device connected to other devices through a switch without bypass function, the device
will lose connection if the switch loses power as traffic will not be able to flow through the link (as
shown in the figure below).

Switches with bypass functions provide one or more sets of bypass ports that ensure constant
network connectivity during power failure.
Packet
PC1 ComNet Bypass Switch PC2
PC1 Packet Bypass to PC2
The CNGE24MS(M,S)2-OB provides two sets of bypass fiber ports, giving the SFP fiber ports
addition redundancy capabilities. Connect a LC fiber cable from a fiber port to a monitor port
on the front panel and another LC fiber cable from the corresponding network port to another
switch.
When the switch breaks down, incoming traffic will travel through the bypass port board and onto
another active switch.
Note that the fiber port will still work if it is not connected to any monitor port. However, the fiber
port will not have bypass ability when the device is down.

Local Counters
Label Description
Local Port The port on which LLDP frames are received or transmitted.
Tx Fr ames The number of LLDP frames transmitted on the port.
Rx Frames The number of LLDP frames received on the port.
Rx Errors The number of received LLDP frames containing some kind of error.
Frames DiscardedIf an LLDP frame is received on a port, and the switch’s internal table has run full, the
LLDP frame is counted and discarded. This situation is known as “Too Many Neighbors”
in the LLDP standard. LLDP frames require a new entry in the table when the Chassis ID
or Remote Port ID is not already contained within the table. Entries are removed from
the table when a given port links down, an LLDP shutdown frame is received, or when
the entry ages out.
TLVs Discarded Each LLDP frame can contain multiple pieces of information, known as TLVs (TLV is short
for “Type Length Value”). If a TLV is malformed, it is counted and discarded.
TLVs
The number of well-formed TLVs, but with an unknown type value.
Unrecognized
Org. Discarded The number of organizationally TLVs received.
Age-Outs Each LLDP frame contains information about how long time the LLDP information is
valid (age-out time). If no new LLDP frame is received within the age out time, the LLDP
information is removed, and the Age-Out counter is incremented.

DHCP Server
Setting
The system provides with DHCP server function. Enable the DHCP server function, the switch
system will be a DHCP server.
DHCP Dynamic Client List
When the DHCP server function is activated, the system will collect the DHCP client information
and display in here.
DHCP Client List
You can assign the specific IP address which is in the assigned dynamic IP range to the specific
port. When the device is connecting to the port and asks for dynamic IP assigning, the system will
assign the IP address that has been assigned before in the connected device.

Label Description
Port This is the logical port number for this row.
Link The current link state is displayed graphically. Green indicates the link is up and red that
it is down.
Current Link
Provides the current link speed of the port.
Speed
Configured Link
Speed
Select any available link speed for the given switch port.
Auto Speed selects the highest speed that is compatible with a link partner.
Disabled disables the switch port operation.
Flow Control When Auto Speed is selected for a port, this section indicates the flow control
capability that is advertised to the link partner.
When a fixed-speed setting is selected, that is what is used. The Current Rx column
indicates whether pause frames on the port are obeyed, and the Current Tx column
indicates whether pause frames on the port are transmitted. The Rx and Tx settings are
determined by the result of the last Auto-Negotiation.
Check the configured column to use flow control. This setting is related to the setting
for Configured Link Speed.
Maximum Frame Enter the maximum frame size allowed for the switch port, including FCS. The allowed
range is 1518 bytes to 9600 bytes.
Power Control Allows for changing the power savings mode parameters per port.
Disabled: All power savings mechanisms disabled.
ActiPHY: Link down power savings enabled.
PerfectReach: Link up power savings enabled.
Enabled: Both link up and link down power savings enabled.
Save Select to save changes.
