iConverter GX/T2
Standalone Module User Manual
Product Overview
The GX/T2 is a 10/100/1000BASE-T UTP to 100BASE-FX or 1000BASE-X modular fiber media
converter that supports jumbo frames up to 10,240 bytes. The GX/T2 features Small Form Pluggable
(SFP) transceivers that support both 100BASE-FX and 1000BASE-X for interoperability with Fast
Ethernet and Gigabit fiber equipment.
Installation Procedure
1) Configure DIP-switches
2) Install Standalone Module and Connect Cables
3) Verify Operation
1) CONFIGURE DIP-SWITCHES
Figure 1: DIP-switch Locations
DIP-SWITCH BANK 1
The location of the DIP-switches is shown in Figure 1. The functions of DIP-switch Bank 1 are
outlined in Figure 2.
SW1: L2CP Block
When this DIP-switch is in the default Down position, the module will forward all L2CP frames. When
the DIP-switch is in the Up position, the module will discard all L2CP frames.
SW2: 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 3.
SW1: Port 1 "Auto/100"
This DIP-switch configures the speed of the transceiver installed in Port 1. If the DIP-switch is in the
Down "Auto" (default) position, the port detects the data rate of the transceiver installed and operates
at 100M or 1G accordingly. If the DIP-switch is in the Up "100" position, the port is expecting a 100M
capable transceiver to be installed.
NOTE: SW1 is not available for fixed fiber models. The fiber port is always set to 1000.

SW5 and SW6: Link Modes "Mode 1" and "Mode 2"
These DIP-switches configure the link mode settings. It is recommended to have link modes DOWN
"Off" position (default) during the initial installation. After the circuit has been tested and operational,
configure the module for the desired 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, the loss of a receive link signal will continue to propagate through to the
next port in the network causing the port to drop link.
Asymmetrical Link Propagate
In Asymmetrical Link Propagate mode, faults are propagated based on the port notation. Port 1 to Port
2 notation indicates the direction the loss of link signal will propagate. A loss of receive link on the fiber
optic Port 1 causes the UTP Port 2 to drop its link due to the propagated state (Port 1 to Port 2). The
loss of link on the in the Port 1 to Port 2 direction. See Figure 5 for valid Link Mode configurations.
