Omnitron Systems Technology iConverter 2GXM - Manual (Page 2)

NOTE: If mounting with a safety ground attachment, use the safety ground
screw at the rear of the unit.
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.
c. 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. A new 2GXM module does not have a password, and will skip the Password
Entry screen and go straight to the Management Options screen. If a password has
been set, the Password Entry screen will be displayed. Type the password and press
<ENTER>, the 2GXM will respond with the Management Options screen:
NOTE: The fiber optic ports operate in Full-Duplex mode in both Auto and Manual
negotiation modes.

2) INSTALL STANDALONE MODULE AND CONNECT CABLES
a. The 2GXM 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 the AC/DC adapter to
the 2.5mm DC barrel connector (center-positive) on the chassis. 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 14 AWG 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 and negative
connections. Use the same color assignment for the connection at the DC
power source.
