Installation Procedure
DFCS XG Standalone
DIP-SWITCH BANK 2
The location of DIP-switch Bank 2 is on the side of the module.
LINK MODES
SW1,SW2, SW3 and SW4 - LINK MODES
These four DIP-switches configure the different link modes available on the XG. It is
recommended to have link modes set to Link Segment (default setting - all DOWN) during
the initial installation. After the circuit has been tested and operational, configure the module
for the desired mode. Refer to Figure 3 for configuration options.

DFCS
XGs connected
via Port 1.
SELF DIAGNOSTIC CIRCUIT TEST (SFP+ models only - LMC11012A and LMC 11022A)
When two XG converters are connected via Port 1 (Port 1 to Port 1), a self diagnostic circuit
test is supported. The XG initiating the circuit test (all DIP-switches to UP) will generate
and send a test pattern out Port 1 to the other XG. The receiving XG will detect a good test
pattern and return the test pattern back to the initiating XG.
A successful test will produce a green blinking (5Hz) P1 LB LED on the initiating XG and a
green blinking (1Hz) P1 LB LED on the receiving XG. If the initiating XG does not receive a
valid response, the P1 LB LED will be blinking amber (5Hz). When the self diagnostic circuit
test is initiated, the traffic received on Port 2 of both XG converters will be discarded.
2) INSTALL STANDALONE MODULE AND CONNECT CABLES
a. The XG is available in tabletop and wall-mount models. For wall-mounting, attach the
XG 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 XG to prevent the unit
from sliding. Make sure the unit is placed in a safe, dry and secure location.
b. 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.
c. Insert the appropriate 10G SFP+ or XFP transceiver into the corresponding port receptacle
on the XG.
NOTE: The release latch of the transceiver must be in the closed position before
insertion.
d. When using copper CX4 XFP, connect the cable between the converter and external
device using the recommended copper CX4 cable.
e. Connect an appropriate multimode or single-mode fiber cable to the fiber transceiver ports
on the XG. 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.
NOTE: FOR LMC11022A AND LMC11002A BOTH TRANSCEIVERS MUST BE INSTALLED
FOR THE XG TO PROPERLY FUNCTION. WHEN ONLY ONE XFP TRANSCEIVER IS
INSTALLED AND THERE IS NO TRANSCEIVER INSTALLED IN THE OTHER PORT, THE
TRANSMITTER OF THE INSTALLED TRANSCEIVER IS DISABLED.
