Omnitron Systems Technology Network Card 2Tx User Manual

In “Remote Fault Detection” (RFD), the UTP port  
transmits a “Link” signal only when receiving a “Link” at  
both the fiber ports. The fiber port transmits a “Link”  
only when receiving “Link” signals both at the fiber port  
and the UTP port. As a result, fiber faults (no “Link”  
received at the fiber) are looped-back and can be reported  
to the network’s core (Not Shown).  
UTP Auto/Manual “AN/MAN” DIP-Switch:  
OVERVIEW:  
BOARD MOUNTED DIP-SWITCH SETTINGS:  
When this DIP-Switch is set to Auto Negotiate “AN”  
(factory setting) it enables the UTP 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  
Manual “MAN”. This feature allows connections with  
devices that do not auto negotiate properly.  
The iConverter Redundant Fast Ethernet manageable  
media converters are members of the modular iConverter  
product family. The following models are described:

In “Symmetrical Fault Detection” (SFD), the UTP port  
transmits a “Link” signal only when receiving a “Link” at  
both the fiber ports. The fiber port transmits a “Link” only  
when receiving “Link” signal from both the fiber ports and  
the UTP port. As a result, fiber faults (no “Link” received  
at the fiber) 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 fiber faults are reported to both ends of  
the network (Not Shown).  
The iConverter Redundant Fast Ethernet modules are  
intended for use in networks that require fiber or copper  
link redundancy. During normal operations Port A is the  
active primary and Port B is the backup secondary. When  
loss of link on Port A is detected, the module automatically  
switches to transmitting on Port B. With a switch over time  
of less than 100 microseconds, these modules provide  
the rapid response time required for ultra critical  
applications. Note: After the link is switched, there will be  
a 5 second delay before that link can been reestablished.  
UTP Full/Half-Duplex “FD/HD” DIP-Switch:  
Fig. 2 Redundant Fiber to Customer  
Port B  
When the UTP Auto/Manual DIP-Switch is in Manual  
“MAN” position (described above), the UTP Full/Half-  
Duplex “FD/HD” DIP-Switch determines the duplex  
operation mode for the UTP port. When set to Full-  
Duplex “FD” (factory setting), the UTP port operates in  
Full-Duplex. When set to Half- Duplex “HD” the UTP  
port operates in Half-Duplex. Adjust the Half/Full-Duplex  
DIP-Switch to match the connecting device and check  
for link status.  
In this example, data flow from a core switch at the  
Central Office is converted from UTP to redundant  
fiber, and converted back to UTP, where it is connected  
to an edge switch at the Customer Premises. If there is  
a loss of link in fiber Port A, the Tx/2Fx converter  
switches to transmitting on fiber Port B, without a service  
disruption to the mission-critical customer.

Link Segment/Propagate “LS/LP” DIP-Switch:  
iConverter Tx/2Fx Dual Fiber Modules  
This DIP-Switch enables the Link Segment “LS” or Link  
Propagate “LP” modes. When in the “LS” position (left,  
factory default), Link Segment mode is enabled. In the “LP”  
or “ON” position (right), Link Propagate mode is enabled.  
Note that for “LS” mode, “LP”, “RFD” and “SFD”,  
DIP-Switches must be in the Left position (factory  
setting).

LINK MODES:  
In order to accommodate different user needs, the  
Redundant iConverters support four different linking modes.  
NOTE that it is recommended keeping the  
Redundant iConverters in the factory default Link  
Segment (LS) setting.  
Return to Port A “RTA/NR” DIP-Switch:  
APPLICATION EXAMPLES:  
8421-1 8423-1 8425-1 8427-1  
When this DIP-Switch is in the Return to Port A “RTA”  
position (factory default), link reestablishment on Port  
A immediately returns data transmission to Port A after  
a link failure in the connection between the A ports.  
Even though the switch over time is less than 100  
milliseconds, there is the possibility of lost data (dropped  
packet) when the Return to Port A “RTA” DIP-Switch  
setting is selected. When the switch is set to Not  
Return to A “NR”, Port B continues to be used for  
transmitting data even after link has been reestablished  
on Port A.

Note that setting more than one of the mode switches  
(“LP”, “RFD” or “SFD”) to the Right position on the  
same module is an illegal mode that will result in  
unpredictable behavior.  
-
iConverter Tx/2Fx SF Single-Fiber Modules  
In “Link Segment” (LS), sometimes referred to as the  
“Normal” mode, a port transmits a “Link” signal  
independently of any received “Link” at any other port.  
For example, the UTP transmits a “Link” regardless of  
either fiber receiving a “Link” [Fig 3(a) & (b)]. Figure 3(a)  
shows the state when all links are functioning correctly.  
Port A LEDs indicate link and activity, while the Port B  
LEDs blink at one Hertz to indicate they are not active,  
but are in “Standby”. Figure 3(b) shows that when the  
fiber link to Port A is broken, Port B becomes active.  
In “Link Propagate” (LP), sometimes referred to as “Link  
Loss Carry Forward”, 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 both fiber ports (Not Shown).

Fig. 1 Redundant Switch Example  
RJ45 Crossover “= / X” Switch (Not Shown):  
When this DIP-Switch is in the “SFD” position (right), the  
Symmetrical Fault Detection mode is enabled. Note that  
when a loss of “Link” occurs between two Redundant Fast  
Ethernet modules, both redundant connections must have  
a loss of incoming “Link” signal in order for this to occur.  
In this example, redundant Switches 1 and 2 are connected  
to Switch 3 via a Tx/2Fx converter. If power fails in  
Switch 1, or if there is a loss of link in the fiber cable, the  
Tx/2Fx converter switches to transmitting on port B and  
routes data flow to Switch 2.  
When connecting the UTP to a hub or switch, set switch to  
Straight-Through “=” (factory setting). When connecting to a  
workstation, set to Crossover “X”.

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 wave-  
length on one end has to match the Rx wavelength on the other.

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 module is  
firmly seated against the backplane.  
2. Secure the module by securing the panel fastener  
screw (attached to module) to chassis front.  
3. Attach the UTP port of Port C via a category 5 cable  
to a 100BASE-TX Ethernet device.  
4. iConverter Redundant Fast Ethernet Modules should  
be deployed in pairs with Port A linked to Port A and  
Port B linked to Port B between the two modules. If  
using iConverter Redundant Fast Ethernet Modules  
with redundant Fx or Fx SF ports, attach Port A fiber  
ports and Port B fiber ports of the two modules via  
an appropriate multimode or single-mode fiber cable.  
The iConverter transmit (Tx) must attach to the  
receive side on other device; the receive (Rx) must  
attach to the transmit. If using iConverter Redundant  
Fast Ethernet Modules with redundant Tx ports, attach  
the UTP ports of the two modules’ Port A via a  
category 5 cable and UTP ports of the two modules’  
Port B via a category 5 cable.  
5. Single fiber (SF) media converter models must be  
deployed in pairs so that the transmission (Tx) and  
reception (Rx) wavelengths of the single-mode (SM)  
ports communicating over a fiber must match the  
reception (Rx) and transmission (Tx) at the opposite  
end. For example, an 8430-1 should be connected  
to an 8431-1.
