c. Connect the UTP port via a Category 5 or better cable to a 10BASE-T, 100BASE-TX or
1000BASE-T Ethernet device.
d. Connect an appropriate multimode or single-mode ber cable to the ber 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. Single-ber (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.

Standalone Module User Manual
Product Overview
The iConverter 2GXT is a standalone, unmanaged media converter with two 10/100/1000 RJ-45
copper ports and two Small Form Pluggable (SFP) ber ports. The 2GXT can be deployed as a dual­channel media converter that provides two independent copper-to-ber converters in one compact module, or deployed as a four-port switch with dual ber ports that can be congured to provide 1:1 uplink protection with less than 50ms switchover.
Installation Procedure
1) Congure DIP-switches
2) Install Standalone Module and Connect Cables
3) Verify Operation
1) CONFIGURE DIP-SWITCHES

Figure 3: Operational Modes
SW3 and SW4: Operational Modes
4-Port Switch Mode
When SW3 and SW4 are in the default DOWN position, the module operates as a 4-Port Layer 2 Ethernet switch.
Dual Media Converter Mode
When SW3 is in the DOWN position and SW4 is in the UP position, the module operates as two separate and independent copper-to-ber media converters, with P1 and P3 as one media converter, and P2 and P4 as the other media converter.
Redundant Fiber Mode
When SW3 is in the UP position, the module operates as a 4-Port Layer 2 Ethernet switch with the ber ports congured as redundant links. When congured for link redundancy, the module will transmit and receive trafc on the primary port (Port 1) and no trafc on the backup port (Port 2). When a ber failure occurs on the primary port, the device will switch over to the backup port within 50msec.
When SW4 is in the DOWN position, the module will remain on the backup port (Port 2) even when a stable connection has been established on Port 1. When SW4 is in the UP position, the module will switch back to the primary port (Port 1) once a stable connection has been established.
SW5: Pause
The Pause DIP-switch sets the ow control functionality for all ports on the module, including pause mode advertisement, pause functionality, and half duplex back pressure. When the DIP-switch is in the Pause UP position, ow control functionality is enabled. When this DIP-switch is in the Pause DOWN position (factory default), ow control functionality is disabled.
If Pause is enabled and the port is in half duplex, then half duplex ow control is enabled. When a port is in half duplex ow control it generates a back pressure signal when internal buffer resources are low.
If Pause is enabled and the port is in full duplex, then full duplex ow control is enabled. When a port is in full duplex ow control and internal buffering resources are low, a pause frame is generated to slow down the trafc ow to the port.
SW6 and SW7: Link Modes
These DIP-switches congure the link mode settings. It is recommended to have link modes DOWN position (default) during the initial installation. After the circuit has been tested and operational, congure the module for the desired mode. Link Modes are only valid when the module is operating in the Dual Media Converter mode.
Link Segment
In Link Segment mode, all ports operate independently. A loss of a receive link signal will only affect the port detecting the loss of signal. All the other ports will continue to generate a link signal.
Link Propagate
In Link Propagate mode, faults are propagated based on the port notation. Port 1 to Port 3 notation indicates the direction the loss of link signal will propagate. A loss of receive link on Port 1 causes Port 3 to drop its link due to the propagated state (Port 1 to Port 3).
SW8: Reserved
This DIP-switch is reserved and must be in the DOWN (default) position.
DIP-SWITCH BANK 2
The functions of DIP-switch Bank 2 are outlined in Figure 4.

Figure 4: DIP-switch Bank 2 Denitions
SW1 and SW2: SFP Port Speed
These DIP-switches congure the speed of the transceivers installed in the SFP ports. If these DIP-switches are in the DOWN (default) position, the ports will detect the data rate of the transceivers installed and operate at 100M or 1G accordingly. If these DIP-switches are in the UP position, the ports are expecting a 100M capable transceivers to be installed.

2) INSTALL STANDALONE MODULE AND CONNECT CABLES
Caution: Use proper ESD protection to reduce the risk of damage to your equipment.
a. The 2GXT is available as a standalone module with integrated wall-mount brackets. Attach
the unit to a wall, backboard or other at surfaces. 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. Conrm 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 (+7 to +60VDC). The Power LED should indicate the presence of power.
NOTE: If mounting with a safety ground attachment, use the safety ground screw at the
rear of the unit.
b. Insert the SFP ber transceiver into the Port 1 SFP receptacle on the 2GXT.
NOTE: The release latch of the SFP Fiber transceiver must be in the closed position
before insertion.
