OVERVIEW

The iConverter GX/Tprovides10/100/1000BASE-TUTP

to 1000BASE-X Fiber conversion as well as rate

conversion between 10BASE-T, 100BASE-TX,

1000BASE-Tand1000BASE-SX/LX.Modelsare available

for multimode (MM) and single-mode (SM) dual fiber,

and single-mode single-fiber (SF).

The GX/T UTP port supports Half-Duplex and Full-

Duplex modes and features an automatic crossover

mode for easy attachment to hubs, switches and

workstations.

TheGX/Tcan be usedasastandardtwo-port UTP tofiber

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

backplane ports to connect to adjacent modules and

accommodate flexible network configurations. The

iConverter19-Module,5-Moduleor 2-ModuleChassishave

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 NetworkManagement Module

(NMM),GX/TMor10/100M.

ADVANCED FEATURES

TheGX/Tfeatures PortVLANandTagVLAN, whichallow

complete control of traffic flow between the front-plane

UTP port, the fiber 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 configuring 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 fiber 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 configuration.

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

backplaneusing the AandB10/100 links. Inthisexample,

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.

Fig.1 In-Band Managed GX/TApplication

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

ManagementModule(NMM),connectingviaitsAbackplane

port to the GX/T, facilitating In-Band management (via the

fiber 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 fiber uplink configuration. This 3-module

configuration provides an effective 10/100/1000 UTP to

4-Port 10/100 managed switch with a gigabit fiber uplink

configuration.

This example shows how the GX/T can be used either

as a traditional managed or unmanaged media

converter, or to create flexible and effective network

switch configurations.

For more information about individual chassis A and B

backplane links, please refer to the specific chassis

usermanual.

LINK MODES

In order to accommodate different user needs, the GX/T

supports five 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 fiber receiving a Link [Fig. 2(a) & (b)].

In Link Propagate (LP), a port transmits a Link signal

onlywhenreceivingaLinkatitsotherport. Forexample,

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),

thefiber port transmits a Link signal only whenreceiving

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),

theUTPport 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

receivedatthefiber)arepropagated 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.
