CNGE24MS-OB(M,S)
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.
Wall-Mounting Measurement (Unit = mm)
Follow the steps below to install the device to a rack.

TECH SUPPORT: 1.888.678.9427
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.

Cables
Ethernet Cables
The CNGE24MS-OB(M,S) switch has standard Ethernet ports. According to the link type, the
switch uses CAT3, CAT4, CAT5 or CAT5-e UTP cables to connect to any other network device (PCs,
servers, switches, routers, or hubs). Please refer to the following table for cable specifications.
Cable Type Max. Length Connector
10BASE-T CAT3, CAT4, CAT5 100Ω UTP 100m (328ft) RJ-45

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).

The CNGE24MS-OB(M,S) 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.
Console Cable
The CNGE24MS-OB(M,S) switch can be managed by the console port. The DB-9 to RJ-45 cable
can be found in the package. You can connect them to the PC via a RS-232 cable with DB-9 female
connector and the other end (RJ-45 connector) connects to console port of the switch.
