ABOUT THIS MANUAL
This document supports revision “xx/10” of the GX/F.
Please refer to the serial number label on the GX/F for
the revision number of your product. This revision
incorporates the following improvements to the GX/F:
1. Product enhancements now prevent unpredictable
behavior under undefined or incompatible DIP-Switch
selections.
2. LINK MODES have been increased to include RFD+LS
and RFD+LP modes. Improvements to LED behavior
have been made to accommodate these new link modes.
OVERVIEW
The iConverter GX/F media converter provides Gigabit
1000X fiber to Fast Ethernet 100FX fiber conversion. It
is a member of the modular iConverter product family
and supports multimode, single-mode and single-fiber
options. The iConverter GX/F repeats, regenerates and
re-times the fiber optic signal, and multiple GX/F repeaters
can be cascaded to extend total network distances.
Using its switch-based architecture, the GX/F can be
used as a two-port fiber converter, or using its two
additional 10/100 Ethernet backplane ports, it can
connect to adjacent modules and accommodate
In-Band management or multi-module configurations
(the different iConverter Chassis models provide
backplane links to connect between adjacent modules).
The GX/F can be used in an unmanaged or managed
fashion. When unmanaged, it can be installed in a chassis
without a management module. To be managed, a
Network Management Module (NMM) or an iConverter
module with built-in management (such as a 10/100M or
GX/TM) must be installed in the same chassis.
Advanced Features
The GX/F features Port VLAN and T ag VLAN, which allow
control of traffic flow between both the fiber ports and the
backplane ports. It also features Port Access Control,
which facilitates enabling and disabling of individual ports.
The GX/F supports reporting of MIB statistics. Statistics
are available for 32 variables per port, reporting a wide
range of real-time packet statistics to provide
performance and operational monitoring.
NOTE: Using the advanced features listed above
requires management via an NMM, or an iConverter
module with built-in management (such as a 10/100M
or a GX/TM) and NetOutlook
a third-party SNMP management software or Telnet.

PORT STRUCTURE
Using a 4-port switch design, the GX/F features a frontplane 1000Mbps Gigabit fiber port (P1), a 100Mbps
Fast Ethernet fiber port (P2) and two 10/100 Ethernet
backplane copper ports (“A” and “B”) that can connect
to adjacent modules within the same chassis.
When the GX/F “A” and “B” Ethernet backplane ports are
enabled (using the “BPAEN” and “BPBEN” DIP-Switches),
they connect via the chassis backplane to the slots on
the left and right sides of the GX/F module. When another
switch-based module with backplane ports such as a
second GX/F or an NMM is installed in an adjacent slot, it
can be connected via the backplane to the GX/F to form
a multi-module configuration.

4Tx Module
Fig. 1 depicts a chassis with three modules plugged
into three of its adjacent backplane slots (beginning
with an odd numbered slot). The adjacent slots are
connected via the backplane using the “A” and “B”
10/100 links. In this example, the GX/F in the center
slot connects to the slot on its left using the “A” link
and to the slot on its right using the “B” link.
The module on the left is a Network Management Module
(NMM) connecting via its “A” backplane port to the GX/F,
facilitating “In-Band” management (via the fiber uplink).
The module on the right is a 4-port 10/100 switch module
(4Tx) connecting to the GX/F via its “B” port. This 3-module
configuration forms an effective managed 4-port 10/100
Ethernet switch with one Gigabit fiber uplink port and one
Fast Ethernet fiber port.
This example shows how the GX/F can be used as a managed
or unmanaged media converter or as a building block in
creating flexible and effective network switch configurations.
For more information about individual chassis “A” and “B”
backplane links, refer to the specific chassis’ user manual.
LINK MODES
In order to accommodate different user needs, the GX/F
supports five different linking modes (see Fig. 2).
In “Link Segment” (LS) mode (“Normal” mode), a port transmits
a Link signal independently of any received Link at any port.
For example, P2 transmits a Link regardless of the receiving
of a Link at P1 [Fig. 2(a) & 2(b)].
In “Link Propagate” (LP) mode (sometimes referred
to as “Link-Loss-Carry-Forward”), a port transmits a
Link signal only when receiving a Link on the other
Page 6
front-plane port, and a loss of a received Link at one
port causes the other front-plane port to drop its link
out. For example, P2 transmits a Link only when
receiving a Link at P1 [Fig. 2(c)].
In Remote Fault Detection + Link Segment (RFD+LS),
the fiber port transmits a Link signal only when receiving
a Link at the fiber port. As a result, fiber faults (no Link
received at the fiber) are looped-back and can be
reported to the network core [Fig. 2(d)].
In “Remote Fault Detection + Link Propagate” (RFD+LP)
mode, the P1 port transmits a Link signal only when both it
and P2 are receiving Link signals. A loss of a received Link
signal at P1 is Looped-back to P1 and propagated to P2,
causing both to stop transmitting the Link signal [Fig. 2(e)].
Also, the loss of a received Link at P2 is propagated to
both P1 and P2, which stop transmitting the Link signal.
NOTE: Connecting two converters both set to RFD is not
supported and will cause a “deadly embrace” lockup (refer
to the Port 1 1000FX Auto-Negotiation DIP-Switch section).
“Symmetrical Fault Detection” (SFD) mode operates
similarly to the Remote Fault Detection (RFD) mode. In
SFD mode, the loss of a received Link at P1 is LoopedBack to P1 and propagated to P2, causing both to stop
transmitting the Link signal [Fig. 2(f)] and also causing
blinking in a connected GX/F P1 “Link” LED indicator.
Connecting two converters which are both set to SFD is
permitted and facilitates a dual-loop-back feature where
P1 fiber faults can be reported to both ends of the network.
NOTE: Converters in SFD mode must be deployed in pairs,
and the “LS” DIP-Switch position must also be selected.

DIP-SWITCH SETTINGS
Front Panel DIP-Switch Settings
Fig. 3 Front Panel DIP-Switches
Link Segment/Link Propagate “LS/LP” DIP-Switch
This DIP-Switch controls the Link Propagate or Link
Segment modes. When the DIP-Switch is in the “LS”
position (factory setting), Link Segment mode is enabled.
In the “LP” position, Link Propagate mode is enabled.
Remote Fault Detection “RFD” DIP-Switch
To enable Remote Fault Detection mode, set the “RFD”
DIP-Switch to the “RFD” position.
To enable RFD + LS mode, also set the LS/LP DIPSwitch to the “LS” position. To enable RFD + LP mode,
set the LS/LP DIP-Switch to the “LP” position.
The RFD DIP-Switch selection is ignored on ports set to
Auto-Negotiation mode.
NOTE: Connecting two converters with both set to RFD
mode is not supported and will cause a “deadly embrace”
lockup.
Symmetrical Fault Detection “SFD” DIP-Switch
To enable Symmetrical Fault Detection mode, set the
“SFD” DIP-Switch to the “SFD” position, the “LS/LP”
DIP-Switch to the “LS” position and the “RFD”
DIP-Switch to the “Off” position.
Any other DIP-Switch configuration will disable
Symmetrical Fault Detection mode.
NOTE: Converters in SFD mode must be deployed in pairs.

Backplane A Enable “BPAEN” DIP-Switch
When the “BPAEN” DIP-Switch is in the “ON” (right) position,
the A Ethernet backplane port is enabled. This port allows
connectivity to an adjacent module. When the “BPAEN”
DIP-Switch is in the “Off” position (left, factory setting), the
A port is isolated from the backplane.
Backplane B Enable “BPBEN” DIP-Switch
When the Backplane B Enable “BPBEN” DIP-Switch is in the
“ON” (right) position, the B Ethernet backplane port is enabled.
This port allows connectivity to an adjacent module. When
the “BPBEN” DIP-Switch is in the “Off” position (left, factory
setting), the B port is isolated from the backplane.
Port 1 1000FX Auto-Negotiation “P1 AN / MAN”
DIP-Switch
When set to the Auto-Negotiate “AN” (factory setting),
this DIP-Switch enables the Gigabit Fiber Port to sense
its duplex mode automatically. If the connected device
cannot provide the proper signal to indicate its own
mode of operation, the P1 Manual “MAN” DIP-Switch
position should be selected to force Full-Duplex mode
Page 10 Page 11 Page 12Page 9
on Port 1. This facilitates the connection to devices that
do not auto-negotiate properly on their Gigabit fiber port.
Note: In order for Gigabit fiber ports to link up, the
linking two devices (ports) must be set to the same
mode (either Manual or Auto-Negotiate).
When the P1 1000FX Fiber is set to Auto-Negotiation
Mode, the device receiving the fault acts as if it is in
RFD mode.
NOTE: In older versions of firmware, RFD was not
defined on ports set to Auto-Negotiation.
Port 2 100Fx Full/Half Duplex “P2 FD / HD”
DIP-Switch
The P2 Full/Half-Duplex DIP-Switch selects the duplex
mode for the 100Mbps (FX) P2 port. When set to
Full-Duplex “FD” (left, factory setting), the P2 port
operates in Full-Duplex mode. When set to Half-Duplex
“HD” position (right), P2 operates in Half-Duplex mode.
NOTE: Port 2 100FX is not defined for Auto-Negotiate
mode per the IEEE802.3 and is always in Manual mode.

The iConverter GX/F modules are hot-swappable and
can be installed into any iConverter chassis. To install
in a chassis, perform the following steps:
1. Slide the
iConverter module into the selected slot
while aligning it with the installation guides. Ensure
that the module is firmly seated against the
backplane.
2. Secure the module to the chassis using the panel
fastener screw (attached to the module).
3. Connect an appropriate multimode or single-mode
fiber cable to the Gigabit P1 fiber port.
4. Connect the cable to a compatible Gigabit device.
5. Connect an appropriate multimode or single-mode
fiber cable to the 100BASE-FX P2 fiber port.
6. Connect the cable to a compatible 100BASE-FX
device.
NOTES: Each transmit (Tx) port must connect to the
receive port of the attached device; the receive (Rx)
port must connect to the transmit port.
When using single-fiber (SF) models, the Tx wavelength
on one end must match the Rx wavelength on the other
and the converters must be used in matched pairs
(example: model 8562-05 must be matched with model
8562-07).
