Omnitron Systems Technology Network Card GX F User Manual

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.

are available for 32 variables per port, reporting a wide  
range of real-time packet statistics to provide  
performance and operational monitoring.  
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  
For wide temperature (-40 to 60º C), add a "W" to the end of the model  
number. Consult factory for extended temperature (-40 to +75º C) models.  
When using single-fiber (SF) media converter models, the Tx wavelength  
on one end has to match the Rx wavelength on the other.  
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 NetOutlookManagement Software,  
a third-party SNMP management software or Telnet.  
For wide temperature (-40 to 60º C), add a "W" to the end of the model

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.  
1 62.5/125µm, 100/140µm multimode fiber up to 220m. 50/125µm  
multimode fiber up to 550m. Refer to the fiber cable manufacturer for  
multimode distance specifications.

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

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.  
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)].  
PORT STRUCTURE  
Using a 4-port switch design, the GX/F features a front-  
plane 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.

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)].

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.  
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.

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.

“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 Looped-  
Back 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.

In order to accommodate different user needs, the GX/F  
supports five different linking modes (see Fig. 2).  
InLinkSegment(LS)mode(“Normalmode), aporttransmits  
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)].
