Getting Started
1.1 About the IGS-9122GPM_CVTL
The IGS-9122GPM_CVTL is a modular managed industrial Ethernet switch with twelve
10/100/1000Base-T(X) ports and two 100/1000Base-X SFP ports. The Gigabit ports provide
high network throughputs to give your network the capacity to handle huge workloads. The
SFP ports can meet demand for long-distance data transmission. The switch comes with three
modular slots to provide more Ethernet ports. The modules support hot-swap installation;
therefore, you don’t need to power off the switch when replacing the module. The switch also
supports Ethernet Redundancy protocol, O-Ring (recovery time < 30ms over 250 units of
connection) and MSTP (RSTP/STP compatible) to protect mission-critical applications from
network interruptions or temporary malfunctions with fast recovery technology. With a wide
operating temperature from -40oC to 75oC, the device can be managed centrally via ORing’s
proprietary Open-Vision platform as well as via Web-based interfaces, Telnet, and console
(CLI). The switch is one of the most reliable choices for highly-managed and fiber Ethernet
applications.

Hardware Installation
3.1 DIN-rail Installation
The device comes with a DIN-rail kit to allow you to fasten the switch to a DIN-rail in any
environments.
DIN-Rail Measurement (Unit = mm)
Installing the switch on the DIN-rail is easy. First, screw the DIN-rail kit onto the back of the
switch, right in the middle of the back panel. Then slide the switch onto a DIN-rail from the
DIN-rail kit and make sure the switch clicks into the rail firmly.
3.2 Wall-mount Installation
The device can be installed on the wall horizontally or vertically using the wall-mount kits in the
package.

IGS-9122GPM_CVTL User Manual
ORing Industrial Networking Corp
12
Step 1: Screw the two pieces of wall-mount kits onto the back of the switch. The wall-mount
kits can be attached to the right and left sides or the top and bottom of the switch.
Step 2: Use the switch, with wall mount plates attached, as a guide to mark the correct

IGS-9122GPM_CVTL User Manual
ORing Industrial Networking Corp
13
locations of the four screws.
Step 3: Insert a screw head through the large parts of the keyhole-shaped apertures, and then
slide the switch downwards. Tighten the screw for added stability.
3.3 Wiring
3.3.1 Fault Relay
The relay contacts on the 7-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 event is triggered. If a user-configured event does not occur, the fault circuit
remains closed.
3.3.2 Redundant Power Inputs
The switch has two sets of power inputs, power input 1 and
power input 2 to provide redundant power. When one of
the power modules breaks down, the other one will take
over immediate to ensure uninterrupted operation. Follow
the steps below to wire redundant power inputs.
Step 1: insert the negative/positive wires into the V-/V+
terminals, respectively.
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
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.

IGS-9122GPM_CVTL User Manual

Step 2: to keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten
the wire-clamp screws on the front of the terminal block connector.
3.3 Connection
3.3.1 Ethernet Cables
1000/100BASE-TX/10BASE-T Pin Assignments
The series provides standard Ethernet ports. According to the link type, the switch uses CAT 3,
4, 5,5e UTP cables to connect to any other network devices (PCs, servers, switches, routers,
or hubs). Please refer to the following table for cable specifications.

3.3.2 SFP
The switch comes with SFP ports that can connect to other devices using SFP modules. The
SFP modules are hot-swappable input/output devices that can be plugged into the SFP ports
to connect the switch with the fiber-optic network. Remember that the TX port of Switch A

IGS-9122GPM_CVTL User Manual
ORing Industrial Networking Corp

should be connected to the RX port of Switch B.
SwitchA Switch B
1. Insert clean dust plugs into the SFPs after the cables are extracted from them.
2. Clean the optic surfaces of the fiber cables before you plug them back into the
optical bores of another SFP module.
3. Avoid getting dust and other contaminants into the optical bores of your SFP
modules in cases of malfunction.
3.3.3 O-Ring/O-Chain
O-Ring
You can connect three or more switches to form a ring topology to gain network redundancy
capabilities through the following steps.
1. Connect each switch to form a daisy chain using an Ethernet cable.
2. Set one of the connected switches to be the master and make sure the port setting of each
connected switch on the management page corresponds to the physical ports connected. For
information about the port setting, please refer to 4.1.2 Configurations.
3. Connect the last switch to the first switch to form a ring topology.

Coupling Ring
If you already have two O-Ring topologies and would like to connect the rings, you can form
them into a coupling ring. All you need to do is select two switches from each ring to be
connected, for example, switch A and B from Ring 1 and switch C and D from ring 2. Decide
which port on each switch to be used as the coupling port and then link them together, for
example, port 1 of switch A to port 2 of switch C and port 1 of switch B to port 2 of switch D.
Then, enable Coupling Ring option by checking the checkbox on the management page and
select the coupling ring in correspond dance to the connected port. For more information on
port setting, please refer to 4.1.2 Configurations. Once the setting is completed, one of the
connections will act as the main path while the other will act as the backup path.

IGS-9122GPM_CVTL User Manual
ORing Industrial Networking Corp

Dual Homing
If you want to connect your ring topology to a RSTP network environment, you can use dual
homing. Choose two switches (Switch A & B) from the ring for connecting to the switches in the
RSTP network (core switches). The connection of one of the switches (Switch A or B) will act
as the primary path, while the other will act as the backup path that is activated when the
primary path connection fails.
O-Chain
When connecting multiple O-Rings to meet your expansion demand, you can create an
O-Chain topology through the following steps.
1. Select two switches from the chain (Switch A & B) that you want to connect to the O-Ring
and connect them to the switches in the ring (Switch C & D).
2. In correspondence to the port connected to the ring, configure an edge port for both of the
connected switches in the chain by checking the box in the management page (see 4.1.2
Configurations).
3. Once the setting is completed, one of the connections will act as the main path, and the
other as the backup path.
