2.3 Bypass Technology
When a device connected to other devices through a switch without bypass function, the
device will lose connection if he switch loses power as traffic will not be able to flow through the
link (as shown in the figure below).
Switches with bypass functions such as the TGPS-9084GT-M12-BP2 provide one ormore sets
of bypass ports that ensure constant network connectivity during power failure.

Hardware Installation
3.1 Wall-mount Installation
Wall-mount Measurement (Unit = mm)
Follow the steps below to mount the switch to the wall.
Step 1: Hold the switch upright against the wall
Step 2: Insert two screws through the screw holes located at the top and bottom of the unit and
fasten the screw to the wall with a screwdriver.
Step 3: Slide the switch downwards and tighten the screws for added stability.

TGPS-9084GT-M12 Series User Manual
ORing Industrial Networking Corp
12
Instead of screwing the screws in all the way, it is advised to leave a space of about
2mm to allow room for sliding the switch between the wall and the screws.
3.2 Wiring
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
3.2.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection on the power connector to the grounding surface prior to
connecting devices.
3.2.2 Fault Relay
The switch uses the M12 A-coded 5-pin male connector on the front panel for relay output. Use
a power cord with an M12 A-coded 5-pin female connector to connect the relay contacts from
the switch. The relay contacts will detect user-configured events and form an open circuit when
an event is triggered.
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.

.
3.2.3 Redundant Power Inputs
The switch provides two sets of power supply on a M23 5-pin connector to enable dual power
inputs.
Step 1: Insert a power cable to the power connector on the device.
Step 2: Rotate the outer ring of the cable connector until a snug fit is achieved. Make sure
the connection is tight.

Console port wiring
The switch has one RS-232 (M12 5pin) console port, located on the front panel. Use a
M12-to-DB9 console cable to connect the console port to your PC's COM port.
3.3.2 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.

TGPS-9084GT-M12 Series User Manual
ORing Industrial Networking Corp
16
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 correspondence 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.

TGPS-9084GT-M12 Series User Manual
ORing Industrial Networking Corp
17
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.

Redundancy
Redundancy for minimized system downtime is one of the most important concerns for
industrial networking devices. Hence, ORing has developed proprietary redundancy
technologies including O-Ring and Open-Ring featuring faster recovery time than existing
redundancy technologies widely used in commercial applications, such as STP, RSTP, and
MSTP. ORing‟s proprietary redundancy technologies not only support different networking
topologies, but also assure the reliability of the network.
4.1 O-Ring
4.1.1 Introduction
O-Ring is ORing's proprietary redundant ring technology, with recovery time of less than 30
milliseconds (in full-duplex Gigabit operation) or 10 milliseconds (in full-duplex Fast Ethernet
operation) and up to 250 nodes. The ring protocols identify one switch as the master of the
network, and then automatically block packets from traveling through any of the network‟s
redundant loops. In the event that one branch of the ring gets disconnected from the rest of the
network, the protocol automatically readjusts the ring so that the part of the network that was
disconnected can reestablish contact with the rest of the network. The O-Ring redundant ring
technology can protect mission-critical applications from network interruptions or temporary
malfunction with its fast recover technology.
4.1.2 Configurations
O-Ring supports three ring topologies: Ring Master, Coupling Ring, and Dual Homing. You
can configure the settings in the interface below.
