1.1 GENERAL DESCRIPTION
The Omnitron iConverter®GX/TM2 is a carrier-class media converter and a Network Interface Device (NID)
that provides 10BASE-T, 100BASE-TX or 1000BASE-T (10/100/1000 UTP) to 1000BASE-X Fiber media
conversion with integrated management.
The GX/TM2 conforms to Ethernet in the First Mile (EFM) fiber standards to support Fiber-to-the-X
(FTTX) Metropolitan access and Enterprise LAN networks. GX/TM2 media converters provide managed
copper demarcation points at the customer premises and network edge, offering service provisioning
functions, such as Quality of Service and Bandwidth Control (rate-limiting) capabilities.
The IP-based remote management of the GX/TM2 can be accessed by Omnitron’s NetOutlook®SNMP
Network Management Software, third-party SNMP clients and Telnet. The management IP address is
configuredmanuallyorasaDHCP client in theconfigurationmenu. IP-lessremotemanagementissupported
via 802.3ah OAM or Secure OAM protocols. A menu-driven CLI is accessible via Telnet, serial console
port, or a modem connection to the serial console port.
IMPORTANT
Thismanual provides information on the installationand configuration of the module usingthecommand
line interface (serial console). For ongoing network management, Omnitron Systems recommends
NetOutlook, an SNMP-based Network Management Software.
NetOutlook provides an efficient, user-friendly way to configure, monitor and manage devices installed
on a single network or on a series of networks by providing an intuitive graphical display with real-time
status and alarm (trap) information. The user can easily manage iConverter equipment on a large
Enterprise network or Metropolitan Area network (MAN) from a single location without the need of
additional resources.
The firmware of the Network Management Module (NMM) and NetOutlook must be the same or
greater than the firmware on the GX/TM2 for the module to be managed.
1.1.1 Advanced Features
The GX/TM2 features Port VLAN, Tag VLAN, ProviderVLAN and QoS prioritization which are defined
in the IEEE 802.1Q, 802.1ad and 802.1p specifications. Ethernet Virtual Connections can be configured
with Provider VLAN to support E-Line and E-LAN connections on Metro Ethernet Networks.
Access to the management control can be restricted with the Port VLAN and Tag VLAN features, helping
to prevent Denial-Of-Service (DoS) and unauthorized management access.
Other advanced features include:
• Real-time MIB statistics reporting (38 variables) • Port Access Control
• 802.3ah OAM and Extensions • cNode Level 1Agent
• SNMPv1, SNMPv2c, SNMPv3
Refer to the appropriate sections for configuration information.

2.0 PORT STRUCTURE
2.1 OVERVIEW
The front panel of the GX/TM2 provides access to the management (serial console), UTP and fiber ports.
The fiber port will vary depending on the connector type; ST, SC, MT-RJ, LC or SFP supporting
1000BASE-FX transceivers. The plug-in module features two additional Ethernet backplane ports
for connectivity via the chassis backplane.

2.1.1 Management Port
PI SA
The GX/TM2 features a Serial RS-232 Console Port (aka Craft Interface) which can be connected to a
computer for initial setup and configuration. The Serial Console Port is accessed through the mini DIN-6
female DCE interface. Connect the interface to a computer’s DB-9 serial port using the mini DIN-6 male
to DB-9 female cable adapter (Part # 8082-0), which is included with the GX/TM2.
An optional DB-9 male to female straight-through serial cable is available for extension (Part # 8081-3).
2.1.2 UTP and Fiber Ports
PI SA
The UTPEthernet port supports 10BASE-T, 100BASE-TX and 1000BASE-T protocols, auto-negotiation
and manual forced modes for half and full duplex. The UTP port can be enabled or disabled via network
management. A port disabled with the Port Access Control feature will still connect and allow 802.3ah
OAM or IP-less (secure) OAM communication, but blocks normal data traffic.
The fiber interface supports the 1000BASE-X protocol. The fiber interface operates in manual mode or
auto-negotiation and supports full duplex operation. The fiber port can be enabled or disabled via network
management. A port disabled with the Port Access Control feature will still connect and allow 802.3ah
OAM or IP-less (secure) OAM communication, but blocks normal data traffic.
2.1.3 Backplane Ethernet Ports
PI
The plug-in module supports two additional 1000Mbps Ethernet Backplane Ports. The Backplane PortsA
and B allow Ethernet data connectivity between adjacent modules that support the gigabit backplane in an
iConverter chassis. The two backplane ports can be disabled or enabled via a DIP-switch or network
management.
The iConverter 19-Module, 5-Module and 2-Module Chassis backplanes provide Ethernet data connectivity
between adjacent slots or ports. TheA and B backplane ports connect the slots as shown in the following
illustration.

3.2.1.1 SW1 - Fiber Auto/Manual Negotiation “AN Man”
When this DIP-switch is in the Auto-Negotiate “AN” position (factory default), the fiber optic port
automatically determines the duplex and pause modes of the connecting fiber optic device. If the connecting
fiber optic device cannot provide the proper signal to indicate its own mode of operation, the DIP-switch
should be set to the Manual mode “Man” position.
Page 6

NOTE: When the fiber optic port operates inAuto-Negotiation mode, the port advertises for Pause.
When the fiber optic port operates in Manual mode, Pause is disabled.
NOTE: The fiber optic port of the GX/TM2 works in Full-Duplex mode in both Auto and Manual
Negotiation modes.
3.2.1.2 SW2 - UTP Auto/Manual Negotiation “AN/Man”
When this DIP-switch is in the “AN” position (factory default), the UTP port automatically determines the
Speed, Duplex and Pause mode of the connecting UTP device. If the connecting UTP device cannot
provide the proper signal to indicate its own mode of operation, then the DIP-switch should be set to the
Manual mode “Man” position. Manual mode requires manually configuring the UTP port to match the
Speed and Duplex mode of the connecting UTP device using the “10/100” and “FDX/HDX” DIP-switches.

3.2.1.3 SW3 - UTP Speed Gigabit/10-100 “1000/10-100”
When the “1000/10-100” DIP-switch is in the “1000” position (factory default), the UTP always operates
in10/100/1000MbpsAuto-Negotiationmode. The UTPport auto-negotiates to a speedof 10Mbps, 100Mbps
or 1000Mbps with the connected UTP device. In this mode, the UTP “AN/Man” and UTP “100/10”
DIP-switches have no effect.
When the “1000/10-100” DIP-switch is in the UP 10/100Mbps “10-100” position and the UTP “AN/Man”
DIP-switch is in the manual “Man” position, the UTP port operates at the Speed and Duplex modes set by
the “10/100” and “FDX/HDX” DIP-switches.
When the “1000/10-100” DIP-switch is in the 10/100Mbps “10-100” position and the UTP “AN/Man”
DIP-switch is in theAuto-Negotiation “AN” position, the maximumAuto-Negotiation setting for the Speed,
Duplex and Pause mode of the UTP port is limited by the “10/100”, “FDX/HDX” and Pause “Off/On”
DIP-switches.
See the UTP Port Configuration Matrix.
3.2.1.4 SW4 - UTP 100/10Mbps “100/10”
When the UTP “AN/Man” DIP-switch (described above) is in the manual “Man” position, the “100/10"
DIP-switch determines the speed of operation for the UTP port. Set the “100/10” DIP-switch to match the
speed of the connected UTP device.
See the UTP Port Configuration Matrix.
3.2.1.5 SW5 - UTP Full/Half Duplex “FDX/HDX”
Setting the UTP Full/Half-Duplex DIP-switch to the “FDX” position (factory default) forces the UTP port
to operate in Full-Duplex. Setting this DIP-switch to UTP Half-Duplex “HDX” forces the UTP port to
operate in Half-Duplex. Adjust the UTP Full/Half-Duplex DIP-switch to match the duplex mode of the
connected UTP device.
See the UTP Port Configuration Matrix.

DIP-switch Bank 2 is available on the plug-in module only.
Switch Left (Factory Default) Right
SW1 A-DS: Port A Disabled A-EN: Port A Enabled
SW2 B-DS: Port B Disabled B-EN: Port B Enabled
SW3 M/SL:
Master/Slave Auto-Select SL: Slave-Mode Only
SW4 Reserved Reserved
3.2.2.1 SW1 - Backplane Port A Enabled “A-DS/A-EN”
When the DIP-switch is in the Left “A-DS” position (factory default), Backplane PortAof the GX/TM2 is
isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane
PortAof the GX/TM2 is enabled. This port allows Ethernet Backplane connectivity to an adjacent module
via the chassis Backplane Port A. See the backplane illustrations in Section 2.1.3.
3.2.2.2 SW2 - Backplane Port B Enabled “B-DS/B-EN”
When the DIP-switch is in the Left “B-DS” position (factory default), Backplane Port B is isolated from the
chassis Backplane. When the DIP-switch is in the Right “B-EN” position, Backplane Port B is enabled.
This port allows Ethernet Backplane connectivity to an adjacent module via the chassis Backplane Port B.
See the backplane illustrations in Section 2.1.3.
3.2.2.3 SW4 - Master/Slave Auto-Select and Slave-Only “M/SL / SL
When multiple management modules such as the iConverter Network Management Module (NMM) and
the GX/TM2 (or multiple self-managed modules such as the 10/100M) are installed in the same chassis,
only one management module can act as the chassis master. The master management module has the
ability to make changes to the settings of the other modules in the chassis, while the slave management
modules cannot make the changes. If an NMM is installed in the chassis, the NMM will always be the
master, otherwise the lowest slot number with a management module installed will become chassis master.
When this DIP-switch is in the Left “M/SL” position (factory default), the assignment of mastership is
automaticallynegotiated by the installed management modules. Todesignate a specific management module
as the master when no NMM is installed in the chassis, set the DIP-switch on the master module to the Left
“M/SL” position, and set the other installed management modules’ DIP-switches to the Right “SL” position
to enable Slave-Only mode.
Only the chassis master can change configuration settings of other modules.
3.2.2.4 SW4 - Reserved
This DIP-switch is for factory use only.
NOTE: DIP-switch marked Reserved must be kept in the Left (factory default) position.

3.3 INSTALLING THE MODULE AND CONNECTING CABLES
PI
a. Carefully slide the module into an open slot in the chassis. Align the module with the installation
guidesand ensure that the module isfirmly seated against the backplane. Secure themodule by fastening
the front panel thumbscrew (push in and turn clockwise to tighten) to the chassis front. Verify the
“Pwr” LED is ON (indicating the chassis is powered).
SA
a. The GX/TM2 standalone Network Interface Device (NID) is available in tabletop and wall-mounting
models. For wall-mounting, attach the NID to a wall, backboard or other flat surfaces. For tabletop
installation, place the unit on a flat and level surface. Attach the rubber feet to the bottom of the NID
to prevent the unit from sliding. Make sure the unit is placed in a safe, dry and secure location.
To power the unit using the AC/DC adapter, connect the AC/DC adapter to the AC outlet. Then
connect the barrel plug at the end of the wire on theAC/DC adapter to the 2.5mm DC barrel connector
(center-positive) on the unit. Confirm that the unit has powered up properly by checking the power
status LED located on the front of the unit.
To power the unit using a DC power source, prepare a power cable using a two-conductor insulated
wire (not supplied) with a 14AWG gauge minimum. Cut the power cable to the length required. Strip
approximately 3/8 of an inch of insulation from the power cable wires. Connect the power cables
to the standalone unit by fastening the stripped ends to the DC power connector.
Connect the power wires to the DC power source. The Power LED should indicate the presence of
power.
WARNING: Note the wire colors used in making the positive, negative and ground connections.
Use the same color assignment for the connection at the DC power source.
NOTE: If mounting with a safety ground attachment, use the safety ground screw at the rearof
the unit.
PI SA
b. When using a GX/TM2 SFP model, insert the SFP Fiber transceiver into the Port 1 SFP receptacle on
the GX/TM2.
NOTE: The release latch of the SFP Fiber transceiver must be in the closed (up) position before
insertion.
c. Connect the UTP port via a Category 5 or better cable to a 10BASE-T, 100BASE-TX or 1000BASE-T
Ethernet device.
d. Connect the appropriate multimode or single-mode fiber cable to the fiber port of the installed module.
It is important to ensure that the transmit (TX) is attached to the receive side of the device at the other
end and the receive (RX) is attached to the transmit side. Single-fiber (SF) media converter models
operate in pairs. The TX wavelength must match the RX wavelength at the other end and the RX
wavelength must match the TX wavelength at the other end.
