The DIP-switches shown in Figure 3 above, are used to configure the link modes. It is
recommended to have link modes DOWN (default) during the initial installation. After the
circuit has been tested and operational, configure the module for the desire mode.

2) INSTALL STANDALONE MODULE AND CONNECT CABLES
a. The GM3 is available in tabletop and wall-mount models. For wall-mounting, attach the
GM3 to a wall, backboard or other flat surface. For tabletop installations, place the unit
on a flat level surface. Attach the rubber feet to the bottom of the GM3 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 an 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 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 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 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.
b. Insert the SFP Fiber transceivers into the SFP receptacles on the GM3.
NOTE: The release latch of the SFP Fiber transceiver must be in the closed position
before insertion.
When using Omnitron SFP fiber transceivers, the GM3 module will detect the speed
and automatically configure the port to match the speed of the SFP. For 3rd party SFP
fiber transceivers, the module may require configuration using the CFM CLI option to
set the speed of the port to match the speed of the SFP. See the full version of the User
Manual for more information.
c. If using a copper SFP, connect the UTP port via a Category 5 cable to a 10BASE-T,
100BASE-TX or 1000BASE-T Ethernet device.
d. Connect an appropriate multimode or single-mode fiber cable to the 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. When using single-fiber (SF) GM3 models, 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.
3) CONFIGURE MODULE VIA COMMAND LINE INTERFACE
To access the Command Line Interface (CLI), connect the GM3 RS-232 Serial 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 GM3 Console Port is a standard
RS-232 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 GM3 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 GM3 will respond
with the Management Options screen.
The CLI interface allows for the detailed configuration of the module. It is recommended to
configure:
Serial port password - option 3 from the Management Options screen •
Telnet password - option 3 from the Management Options screen •
IP address of the module - option 3 from the Management Options screen •
SNMP parameters - option 4 from the Management Options screen •
See the full version of the User Manual for more information.
