GX/T User Manual

OVERVIEW

The iConverter GX/T provides 10/100/1000BASE-T
UTP to 1000BASE-X Fiber conversion as well as
rate conversion between 10BASE-T, 100BASE-TX,
1000BASE-T and 1000BASE-SX/LX. Models are
available for multimode (MM) and single-mode (SM)

dual ber, and single-mode single-ber (SF).

The GX/T UTP port supports Half-Duplex and Full­Duplex modes and features an automatic crossover
mode for easy attachment to hubs, switches and
workstations.

The GX/T can be used as a standard two-port UTP to

ber converter. It can also use its two additional 10/100

backplane ports to connect to adjacent modules and
accommodate flexible network configurations. The
iConverter 19-Module, 5-Module or 2-Module Chassis
have backplanes that facilitate connectivity between
adjacent modules.

The GX/T can be used in a managed or unmanaged
application. When managed, it must be installed in a
chassis with an iConverter Network Management Module
(NMM), GX/TM or 10/100M.

ADVANCED FEATURES

The GX/T features Port VLAN and Tag VLAN, which

allow complete control of trafc ow between the front­plane UTP port, the ber port and the chassis backplane

ports. The GX/T also features Port Access Control, which

facilitates enabling and disabling of individual ports. It
also supports reporting of MIB statistics.

NOTE: Using the advanced features listed above
requires the use of the Network Management Module
(NMM) and the NetOutlook™ Management Software
(or third-party SNMP management software) or Telnet.

For more information on using and conguring these

advanced features, please refer to the NetOutlook
Management Software user manual.

PORT STRUCTURE

Using a 4-port switch design, the GX/T features
two front-plane ports (1000Mbps ber Port 1 and a
10/100/1000 UTP Port 2) and two 10/100 Ethernet
backplane ports (A and B) that can connect to adjacent
modules within the same chassis.

When the GX/T backplane A and B ports are enabled

(using “BPAEN” and “BPBEN” DIP-Switches), they

connect via the chassis backplane to the slots on the
left and right sides of the GX/T module. When another
switch-based module with backplane port connections
(such as a second GX/T or an NMM) is installed in an
adjacent slot, it can be connected via the backplane

to the GX/T to facilitate a multi-module conguration.

GX/T Application Example:

Fig. 1 depicts a chassis with three modules plugged into
three 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/T in the center slot connects to the slot on its left
using the A link and the slot on its right using the B link.

In this example, the module on the left is a Network

Management Module (NMM), connecting via its A backplane

port to the GX/T, facilitating In-Band management (via the
ber uplink). The module on the right is a 4-port 10/100 switch

module, connecting via its B link port to the GX/T, facilitating a

1-Port GX/T and a 4-Port 10/100 Ethernet switch with a ber
uplink conguration. This 3-module conguration provides

an effective 10/100/1000 UTP to 4-Port 10/100 managed

switch with a gigabit ber uplink conguration.

This example shows how the GX/T can be used
either as a traditional managed or unmanaged media

converter, or to create exible and effective network
switch congurations.

For more information about individual chassis A and

B backplane links, please refer to the specic chassis

user manual.

LINK MODES

In order to accommodate different user needs, the GX/T
supports ve different linking 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 ber 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

ber port [Fig. 2(c)].

In Remote Fault Detection + Link Segment (RFD+LS),
the ber port transmits a Link signal only when receiving
a Link at the ber port. As a result, ber faults (no
Link received at the ber) 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 ber port. The ber port transmits a Link
signal only when receiving Link signals at both the ber
port and the UTP port. As a result, ber faults (no Link
received at the ber) 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.

Page 5 Page 6 Page 7 Page 8

Page 2 Page 3

In Symmetrical Fault Detection (SFD), the UTP port

transmits a Link signal only when receiving a Link at

the ber port. The ber port transmits a Link signal only
when receiving a Link signal at both the ber port and
the UTP port. As a result, ber faults (no Link received
at the ber) are looped back and can be reported to the
network core. In addition, connecting two back-to-back

converters which are both set to SFD facilitates dual-

loop-back, where ber faults are reported to both ends
of the network. A blinking ber link LED on a converter
indicates a fault of the transmit ber or UTP cables of
that converter [Fig. 3(f)].

NOTE: Converters in SFD mode must be deployed
in pairs.

Fiber set to Auto-Negotiation Mode

When the Fiber is set to Auto-Negotiation Mode, the

device receiving the fault acts as if it is in RFD mode.

Link Segment, Link Propagate and Symmetrical Fault
Detection modes operate in the same manner (refer to
Fig. 2(d), (e) and (f).

NOTE: “Remote Fault Detection” (RFD) is not a valid

mode when the ber is set to Auto-Negotiation. The user

should select LS, LP or SFD instead.

Fig. 4 Board Mounted DIP-Switches

Backplane A Enable DIP-Switch (BPAEN)

When the “BPAEN” DIP-Switch is in the “ON” position

(right), the iConverter GX/T module A backplane Ethernet
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” position (right), the iConverter GX/T module
B backplane Ethernet 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.

Fiber Auto/Manual P1 “AN/MAN” 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 devices that
do not auto-negotiate properly.

Page 9

NOTE: When the fiber port is in Manual Mode,
sometimes a link-up will 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.

UTP Auto/Manual P2 “AN/MAN” DIP-Switch

Setting the P2 Auto/Manual Negotiate DIP-Switch to
Auto-Negotiate “AN” (factory setting) enables the
UTP port to determine the speed and 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 P2 Manual

“MAN.” This feature allows connections with devices
that do not auto-negotiate properly.

NOTE: Attaching an auto-negotiating UTP port to a non
auto-negotiating (manual/forced/hard-coded) UTP port
may result in an unpredictable port setting with excessive
collisions and poor link performance. When operating in
manual mode, both mating ports MUST be set manually
to the same speed and duplex mode.

Gigabit devices typically function only in Auto-Negotiate
Mode. 1000 Manual Mode is not a valid mode and will

result in an undened response. Use Manual mode only

when selecting the 10 or 100 mode.

UTP Full/Half-Duplex P2 “FD/HD” DIP-Switch

When the UTP P2 Auto/Manual DIP-Switch (described

above) is in the P2 Manual “MAN” position, the UTP P2

Full/Half Duplex “FD/HD” DIP-Switch selects the duplex

mode for the UTP port. When set to Full-Duplex “FD”
(factory setting), the UTP port operates in Full-Duplex
mode. When P2 is set to Half-Duplex “HD,” the UTP
port operates in Half-Duplex mode.

Page 10 Page 11

UTP 10/100 P2 “10/100” DIP-Switch

When the UTP P2 Auto/Manual DIP-Switch is in the

Auto-Negotiate “AN” position and the “10-100/1000”

DIP-Switch (described below) is set to “10-100,” the
“10/100” DIP-Switch determines the highest speed of

the UTP P2 port in the following manner:

When the “10/100” DIP-Switch is set to the “100” position,

P2 operates at 100Mbps or less, depending on the speed
of the connected device.

When the “10/100” DIP-Switch is set to the “10” position,

P2 operates only at 10Mbps.

When the UTP P2 Auto/Manual DIP-Switch is in the

Manual “MAN” position and the UTP “10-100/1000”

DIP-Switch (described below) is set to “10-100,” the
“10/100” DIP-Switch determines the speed of the UTP

P2 port. When set to “100” (factory setting), the UTP port
will operate at 100Mbps. When set to “10,” the UTP port
will operate at 10Mbps.

UTP 10-100/1000 P2 “10-100/1000” DIP-Switch

When the P2 “AN/MAN” DIP-Switch is set to the
Auto-Negotiate “AN” position, the “10-100/1000”

DIP-Switch operates in the following manner:

When set to “1000,” P2 operates at 1000Mbps or less,
depending on the speed of the connected device. When
set to the “10-100” position, the speed is selected by the

UTP “10/100” DIP-Switch.

When the P2 “AN/MAN” DIP-Switch is set to Manual
“MAN” mode, the “10-100/1000” DIP-Switch must be

set to the “10-100” position and the speed is selected

by the “10/100” DIP-Switch.

NOTE: Setting the “10-100/1000” DIP-Switch to the
“1000” position when in Manual mode is not permitted
(per the IEEE 802.3 standard) and will result in
unpredictable port behavior.

Auto/Manual Crossover Enable P2 “AX/MANX”
DIP-Switch

When the Manual/Auto Crossover Enable DIP-Switch

is set to Auto Crossover “AX” (factory default), the

front panel crossover switch is disabled and the RJ-45

crossover is selected automatically. When it is set

to Manual Crossover “MANX,” the front panel RJ-45
Manual Crossover DIP-Switch is enabled to allow a

manual setting in either Crossover or Straight-Through
connection.

Mounting and Cable Attachment

iConverter modules are hot-swappable and can be

installed into any chassis in the iConverter family.

1. Carefully slide the iConverter module into the
installation slot, aligning the module with the
installation guides. NOTE: Ensure that the module

is rmly seated against the backplane.

2. Secure the module by securing the panel fastener
screw (attached to module) to the chassis front.

3. Attach the UTP port via a category 5 cable to a
1000BASE-T, 100BASE-TX or 10BASE-T Ethernet
device.

4. Attach the ber port via an appropriate multimode or
single-mode ber cable to a 1000BASE-X Ethernet

device. The iConverter transmit (Tx) must attach to

the receive side on other device; the receive (Rx)

must attach to the transmit.

5. When using single-ber (SF) media converter models,
the Tx wavelength on one end has to match the Rx

wavelength on the other. Note that based on this
guideline, the SF media converter models must be
used in pairs, such as the 8530-1 matched with the
