1.1 GENERAL DESCRIPTION
The Omnitron iConverter®2FXM2 Network Interface Device (NID) with integrated management provides
Fast Ethernet (100BASE-FX) fiber-to-fiber media conversion. It is also a managed optical switch that
functions as a fiber repeater performing the Three Rs: Retiming, Reamplification and Reshaping of the
fiber optic signal.
The 2FXM2 conforms to Ethernet in the First Mile (EFM) fiber standards to support Fiber-to-the-X (FTTX)
Metropolitan and Enterprise LAN networks. 2FXM2 NIDs are used to provide managed demarcation
points at the customer premises and network edge, offering Quality of Service and Bandwidth Control
(rate-limiting) capabilities.
The IP-based remote management of the 2FXM2 can be accessed by Omnitron’s NetOutlook®SNMP
Network Management Software, third-party SNMP clients and Telnet. The management IP address is
configuredmanuallyoras aDHCP clientin theconfiguration menu. IP-lessremote managementis supported
via 802.3ah OAM or Secure OAM protocol. 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 installation andconfiguration of the module usingthe command
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 2FXM2 for the module to be managed.
1.1.1 Advanced Features
The 2FXM2 features Port VLAN,TagVLAN, 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:
• Bandwidth Control (Rate Limiting) • Layer2 ControlProtocol (L2CP)Filter
• 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 2FXM2 provides access to the management (serial console) and fiber ports. The
SFPfiber ports support 100BASE-FX transceivers. The plug-in module features two additional Ethernet
ports for connectivity via the chassis backplane.
2.1.1 Management Port
PI SA
The 2FXM2 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 2FXM2.
An optional DB-9 male to female straight-through serial cable is available for extension (Part # 8081-3).
2.1.2 Fiber Ports
PI SA
The fiber interfaces support the 100BASE-FX protocol. The fiber interfaces operate in manual mode and
support half or full duplex operation. The fiber ports 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 10/100Mbps Ethernet Backplane Ports. The Backplane Ports
A and B allow Ethernet data connectivity between adjacent modules 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, 2-Module and 1-Module Redundant Chassis backplanes provide
ethernet data connectivity between adjacent slots or ports. The A and B backplane ports connect the slots
as illustrated.

3.2.1.1 SW1 - Pause Disable/Enable “Off/On”
Pause operation is based on the Pause Disable/Enable DIP-switch setting. Setting the Pause DIP-switch to
the “Off” position (factory default) forces the port to operate in No Pause mode. Setting the Pause
DIP-switch to the “On” position allows the port to operate in Symmetrical Pause mode.
3.2.1.2 SW2 - Fiber Port 1 Full/Half-Duplex “FDX/HDX”
When the DIP-switch is in the Full Duplex “FDX” position (factory default), the fiber port will facilitate a
connection that supports Full-Duplex operation. Setting this DIP-switch to Half-Duplex “HDX” facilitates
a connection that supports only Half-Duplex.
3.2.1.3 SW3, SW4 - Reserved
These DIP-switches are for factory use only.

NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.
3.2.1.5 SW5 - Fiber Port 2 Full/Half Duplex “FDX/HDX”
When the DIP-switch is in the Full Duplex “FDX” position (factory default), the fiber port facilitates a
connection that supports Full-Duplex operation. Setting this DIP-switch to Half-Duplex “HDX” facilitates
a connection that supports only Half-Duplex.
3.2.1.6 SW6, SW7, SW8 - Link Modes
These three DIP-switches configure the link mode settings. The following table details possible Link Mode
DIP-switch configurations.

DIP-switch Bank 2 is only available on the plug-in module.
Switch Left (Factory Default) Right
SW1 A-DS:
Backplane Port A Disabled A-EN: Port A Enabled
SW2 B-DS:
Backplane Port B Disabled B-EN: Port B Enabled
SW3 Reserved Reserved
SW4 M/SL:
Master/Slave Auto-Select SL: Slave-Mode Only
SW5 - SW8 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 Port A of the 2FXM2 is
isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane
PortA of the 2FXM2 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 2FXM2 (or multiple self-managed modules such as the 2FXM2) 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 managementmodules. To designate a specific managementmodule
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 SW3, SW5, SW6, SW7, SW8 - Reserved
These DIP-switches are for factory use only.
NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.

3.3 INSTALLING PLUG-IN MODULES AND CONNECTING CABLES
PI
a. Carefully slide the module into an open slot in the chassis. Align the module with the installation
guides and ensure that the module is firmly seated against the backplane. Secure the module 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 2FXM2 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
installations, place the unit on a flat 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 theAC/DC adapter, connect theAC/DC adapter to theAC 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 2FXM2 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 and negative 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 rear of
the unit.
PI SA
b. Insert the SFP Fiber transceivers into the Port 1 and Port 2 SFP receptacles on the 2FXM2.
NOTE: The release latch of the SFP Fiber transceiver must be in the closed (up) position before
insertion.
c. 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. When using single-fiber (SF) media converter
models, the Tx wavelength on one end has to match the Rx wavelength on the other. Based on this
guideline, single fiber SFP fiber transceiver models must be used in pairs, such as the 7014-1 matched
with the 7015-1.
NOTE: In order to support Remote OAM Management Mode, Port 1 of the 2FXM2 must be
connected to the Port 1 on the 2FXM2 or 10/100M2 link partner.

3.4 CONFIGURE THE MODULE VIA COMMAND LINE INTERFACE
PI SA
To configure, attach the 2FXM2 to a DB-9 serial (RS-232) equipped computer with terminal emulation
software such as HyperTerminal. The 2FXM2 Serial Console Port (DCE) is a mini DIN-6 female connector
which can be changed to a DB-9 connector with the included adapter (Part #8082-0). Attach the ends of a
serial cable to the serial port of the PC and the Serial Console Port of the 2FXM2. This is a standard
asynchronous serial interface. The pin-outs are illustrated below.
