FlexPoint™ GX/T

Ethernet Media Converter

User Manual

DESCRIPTION:

The FlexPoint GX/T is a 10/100/1000BASE-T UTP to
1000BASE-X fiber media converter that supports jumbo
frames up to 10,240 bytes. The GX/T features Small
Form Pluggable (SFP) transceivers that support both
100BASE-FX and 1000BASE-X for interoperability with
Gigabit and Fast Ethernet fiber equipment.

Both the fiber port and the UTP port support auto­negotiation, an IEEE standard which defines how all the
communicating devices automatically perform their
configuration functions.

The auto-negotiation feature can be disabled on both ports
(for manual configuration) using DIP-switches on the
product. This is useful in a situation where the GX/T is
connected to a non-negotiating device and the configuration
parameters must be set manually.

POWER ADAPTER NOTICE:

1. This product should only be used with Omnitron Supplied
Power Unit model numbers 9113-PS [US] or 9115-PS
[Universal].

2. When used in a standalone configuration, this product
must be used with a Listed Direct Plug-In Power Unit
marked “Class 2” and rated at 9VDC, 1 Amp.

NOTE: If mounting with a safety ground attachment,
use the safety ground screw at the rear of the unit.

NOTE: Remove safety ground screw when installing
the module in the 14-Module Chassis or when using

it with the DC-DC Converter (Model # 4384)

WARNING!

Before inserting the Power Adapter, verify
that the power on the unit is appropriate

for your AC line voltage source.

INSTALLATION PROCEDURE

1.) Configure the appropriate FlexPoint GX/T DIP-Switch
settings.

2.) Connect the UTP port via a Category 5 or better cable
to a 10BASE-T, 100BASE-TX or 1000BASE-T Ethernet
device.

3.) When using fixed fiber port models, connect the
appropriate multimode or single-mode fiber cable to the
fiber 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-fiber (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.

4.) When using a GX/T SFP model, insert the SFP Fiber
transceiver into the Port 1 SFP receptacle on the GX/T.

NOTE: The release latch of the SFP Fiber transceiver
must be in the closed (up) position before insertion.

LOOPBACK

The FlexPoint GX/T has the capability to provide loopback
to aid in installation and maintenance. A DIP-switch is
used to enable loopback on the module (see page 7).
Figure 1 shows the module in normal and loopback modes.

LINK MODES

In order to accommodate different user needs, the GX/T
supports four different link modes (see Fig. 2).

In Link Segment (LS), a port transmits a Link signal
independently of any received Link at any other port. For
example, the UTP transmits a Link regardless of the fiber
receiving a Link [Fig. 2(a) & (b)].

In Link Propagate (LP), a port transmits a Link signal only
when receiving a Link at its other port. For example, the
UTP transmits a Link only when receiving a Link at the
fiber port [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),
the UTP port transmits a Link signal only when receiving
a Link at the fiber port. The fiber port transmits a Link
signal only when receiving Link signals at both the fiber
port and the UTP port. As a result, fiber faults (no Link
received at the fiber) are propagated forward and looped
back for fault reporting at both the network core and the
customer location [Fig. 2(e)].

NOTE: Connecting two converters with both set to RFD
mode is not supported and will cause a “deadly embrace”
lockup.

DIP-SWITCHES

F/O Manual/Auto “MAN/AN” DIP-Switch:

Setting this DIP-Switch to P1 Auto-Negotiate “AN” (factory
setting) enables the Fiber Port to determine duplex mode
automatically. If the connected device cannot provide
the proper signal to indicate its own mode of operation,
this DIP-Switch should be set to P1 Manual “MAN.” This
feature allows connections with legacy devices that do
not support auto-negotiation.

NOTE: When the fiber port is in Manual Mode, a link-up
may not occur with other devices. Both devices must be
set to the same mode (either Manual or Auto-Negotiate) for
the link-up to occur.

When set to auto-negotiation, the fiber port will
automatically reconfigure to manual mode when an auto­negotiation connection cannot be established.

F/O Speed “100/1000” DIP-Switch:

The GX/T supports 100BASE-FX and 1000BASE-X SFPs.
This DIP-switch is used to configure the unit for the
speed of SFP used. Setting this DIP-switch to “1000”
enables the fiber port is accept 1000BASE-X SFPs. Setting
this DIP-switch to “100” enables the fiber port to accept
100BASE-FX SFPs. This DIP-switch is only available on
the SFP model.

This DIP-switch is ignored when using Omnitron branded
SFPs. The GX/T automatically configures the fiber port
to the correct speed.

UTP Configuration DIP-Switches:

See the UTP Modes table on page 8.

Pause “On/Off” DIP-Switch:

In auto-negotiation mode, setting this DIP-switch to “On”
allows the unit to advertise as Symmetrical and
Asymmetrical Pause capability . In auto-negotiation mode,

setting the DIP-switch to “Off” causes the unit to advertise
no Pause capability. In the manual mode, this DIP­switch determines the Symmetrical Pause behavior.

Loopback “Off/On” DIP-Switch:

Setting this DIP-switch “On” enables loopback on the
fiber and UTP ports (see Figure 1).

Link Modes:

See the following table for configuring link modes:

LS Normal Enables Link Segment mode (LS).

NOTE: RFD is only available when the fiber port is
operating in manual mode.

REMOTE FAULT

Each port will generate an “IEEE remote_fault indicator”
when the incoming signal to the port is lost. When a port
is configured for auto-negotiation, it will set the remote
fault bit “high” in the AN advertisement when the port
detects a loss of incoming signal. See LED Indicators
table on page 9 for specifics on how the unit reports the
detection of this signal.

When the fiber port is operating in 100BASE-FX, a loss of
incoming signal will cause the port to generate a Far-End­Fault indicator pattern. See LED Indicators table on page
9 for specifics on how the unit reports the detection of
this signal.
