SA
1.1 GENERAL DESCRIPTION
The Omnitron iConverter®2GXM Network Interface Device (NID) with integrated management provides
Gigabit Ethernet (1000BASE-X) 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 2GXM conforms to Ethernet in the First Mile (EFM) fiber standards to support Fiber-to-the-X (FTTX)
Metropolitan and Enterprise LAN networks. 2GXM NIDs are used to provide managed demarcation points
at the customer premises and network edge, offering Quality of Service capabilities.
TheIP-basedremotemanagement of the2GXMcanbeaccessed by Omnitron’sNetOutlook®SNMPNetwork
Management Software, third-party SNMP clients and Telnet. The management IP address is configured
manually or as a DHCP client in the configuration menu. IP-less remote management is 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 onthe installation and configurationof the moduleusingthe 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 2GXM for the module to be managed.
1.1.1 Advanced Features
The 2GXM features Port VLAN,Tag VLAN, Provider VLAN 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) • 802.3ah OAM and Extensions
• Port Access Control • 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 2GXM provides access to the management (serial console) and fiber ports. The
fiber ports are SFPsupporting 1000BASE-FX transceivers. The plug-in module features two additional
Ethernet ports for connectivity via the chassis backplane.
2.1.1 Management Port
PI SA
The2GXM features aSerialRS-232 Console Port(aka Craft Interface)which can be connectedto 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 2GXM.
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 interface supports the 1000BASE-X protocol. The fiber interface operates in auto-negotiation or
manual mode 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 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. TheA and B backplane ports connect the slots
as illustrated.

SW5 - SW8 Reserved Reserved
3.2.2.1 SW1 - Backplane Port AEnabled “A-DS/A-EN”
When the DIP-switch is in the Left “A-DS” position (factory default), Backplane Port A of the 2GXM is
isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane
Port A of the 2GXM 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. Page 7

3.2.2.3 SW3 - Pause Disable/Enable “Off/On”
When the Pause enable/disable DIP-switch is in the Left “Off” position (factory default), Port 2 of the
2GXM does not send, receive and/or react to Pause frames during network congestion. Setting this DIP-
switch to the Right “On” position enables Port 2 of the 2GXM to send, receive and/or react to Pause frames
to/from its link partner. This enables the 2GXM to stop transmitting traffic to its link partner and store
incoming frames from the other port in the internal buffer until the congestion clears. If the internal buffer
of the 2GXM becomes congested, it will transmit a Pause frame to its link partner.
NOTE: When Port 1 operates in Auto-Negotiation mode, the port advertises for Pause. When the
Fiber optic ports (Port 1 and Port 2) operate in Manual mode, Pause is disabled.
3.2.2.4 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 2GXM (or multiple self-managed modules such as 2GXM) 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 installedmanagementmodules. To designateaspecific 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.
3.2.2.5 SW3, SW5, SW6, SW7, SW8 - Reserved
These DIP-switches are for factory use only and must always remain in the LEFT position (factory default).
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
guidesandensure that the module isfirmly 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 2GXM 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 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 2GXM 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 2GXM.
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 7214-1 matched
with the 7215-1.
NOTE: In order to support Remote OAM Management Mode, Port 1 of the 2GXM must be
connected to the Port 1 on the 2GXM or link partner.
Page 9

3.4 CONFIGURE THE MODULE VIA COMMAND LINE INTERFACE
PI SA
To configure, attach the 2GXM to a DB-9 serial (RS-232) equipped computer with terminal emulation
software such as HyperTerminal. The 2GXM 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 2GXM. This is a standard
asynchronous serial interface. The pin-outs are illustrated below.

The Soft-switch Reload function controls the configurations of the 2GXM and other iConverter modules
managed by the 2GXM following a power up.
When the Soft-switch Reload is disabled, the configurations of the 2GXM and the other managed modules
(non-management modules) are determined by their hardware DIP-switch settings following the return of
power.
When the Soft-switch Reload is enabled, the configurations of the 2GXM and the other managed modules
are determined by the previous software settings stored in the FLASH memory of the 2GXM following a
return of power. Each of the hardware DIP-switch settings on the module are ignored until a change is
made to the DIP-switch, then the hardware settings will take effect.
