User's Manual
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.
SW4 - MASTER/SLAVE
When the 2GXM module is installed in a chassis with an
iConverter Network
Management Module (NMM), the DIP-switch must be set to the LEFT “M/SL” position
(factory default). The assignment of mastership is automatically negotiated by
the installed management modules. To designate the 2GXM module as the master
of the chassis, set the DIP-switch to the LEFT “M/SL” position, and set the DIP-
switches on the other installed management modules to the RIGHT “SL” position to
enable Slave-Only mode.
SW5, SW6, SW7, SW8 - RESERVED
These DIP-switches are for factory use only and must always remain in the LEFT
position (factory default).
2) INSTALL MODULE IN CHASSIS AND CONNECT CABLES
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).
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
position before insertion.
d. Connect an appropriate multimode or single-mode fiber cable to the SFP fiber
ports 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.
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.
3) CONFIGURE MODULE VIA COMMAND LINE INTERFACE
To access the Command Line Interface (CLI), connect the 2GXM RS-232 Console
Port to the COM port of a computer equipped with terminal emulation software such as
HyperTerminal. The Console Port (DCE) is a mini DIN-6 female connector which can
be changed to a DB-9 connector with the included adapter. The 2GXM Console Port
is a standard asynchronous serial interface.
Start HyperTerminal and select the correct COM Port in the HyperTerminal “Connect
To:” window. Set the serial port to the following:
Bits Per Second 57,600
Stop Bits 1
Data Bits 8
Parity NONE
Hardware Flow Control NONE
Once connected, press <ENTER> to bring up a command line prompt on the attached
PC.
SW3, SW4, SW5 - RESERVED
These DIP-switches are for factory use only and must always remain in the LEFT
position (factory default).
SW6, SW7, SW8 - LINK MODES
These three DIP-switches configure the link mode settings. The following table details
possible Link Mode DIP-switch configurations. For detailed information on the operation
of the different Link Modes, download the application note “iConverter Link Modes”
available on Omnitron’s web page:

DIP-SWITCH BANK 2
SW1, SW2 - BACKPLANE ENABLE
When the DIP-switch is in the LEFT
“DS” position (factory default), the
Backplane Port of the 2GXM is
isolated from the chassis’ Ethernet
Backplane. When the DIP-switch is
in the RIGHT “EN” position, the
Backplane Port is enabled. This
allows Ethernet Backplane
connectivity to an adjacent module
via the chassis Backplane Link “A”
or “B” depending on the switch setting.
SW3 - PAUSE DISABLE/ENABLE
When the Pause disable/enable DIP-switch is in the LEFT “Off” position (factory default),
Port 2 of the 2GXM does not send, receive 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 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.
