Manual

OVERVIEW:

The iConverter Redundant Fast Ethernet manageable
media converters are members of the modular iConverter
product family. The following models are described:
Tx/2Fx 100BASE-TX UTP to dual 100BASE-FX dual

ber

Tx/2Fx SF 100BASE-TX UTP to dual 100BASE-FX

single-ber

Tx/2Tx 100BASE-TX UTP to dual 100BASE-FX UTP
The iConverter Redundant Fast Ethernet modules are

intended for use in networks that require ber 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.

APPLICATION EXAMPLES:

Fig. 1 Redundant Switch Example

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 ber
cable, the Tx/2Fx converter switches to transmitting on
port B and routes data ow to Switch 2.

Page 2

Fig. 2 Redundant Fiber to Customer

In this example, data ow from a core switch at the
Central Ofce is converted from UTP to redundant ber,
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 ber Port A, the Tx/2Fx converter switches to
transmitting on ber Port B, without a service disruption
to the mission-critical customer.

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.

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
ber 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 ber 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

ber ports (Not Shown).

Page 3

In “Remote Fault Detection” (RFD), the UTP port transmits

a “Link” signal only when receiving a “Link” at both the ber
ports. The ber port transmits a “Link” only when receiving
“Link” signals both at 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’s core

(Not Shown).
In “Symmetrical Fault Detection” (SFD), the UTP port

transmits a “Link” signal only when receiving a “Link” at

both the ber ports. The ber port transmits a “Link” only
when receiving “Link” signal from both the ber ports 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-loop­back where ber faults are reported to both ends of the

network (Not Shown).

BOARD MOUNTED DIP-SWITCH SETTINGS:

Fig. 4 Board Mounted DIP-Switches

Link Segment/Propagate “LS/LP” DIP-Switch:

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”, DIP­Switches must be in the Left position (factory setting).

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.

Remote Fault Detection “RFD” DIP-Switch:

When in the “RFD” position, the Remote Fault Detection
mode is enabled.

Note that connecting two converters with both set
to RFD mode is illegal and will cause a “deadly em­brace” lockup.

Symmetrical Fault Detection “SFD” DIP-Switch:

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.

UTP Auto/Manual “AN/MAN” DIP-Switch:

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.

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

When the UTP Auto/Manual DIP-Switch is in Manual
“MAN” position (described above), the UTP Full/Half­Duplex “FD/HD” DIP-Switch determines the duplex
operation mode for the UTP port. When set to Full­Duplex “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.

Return to Port A “RTA/NR” DIP-Switch:

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 modules connected together must be set to
the same mode for correct operation.

RJ45 Crossover “= / X” Switch (Not Shown):

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”.

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 module is rmly 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 ber
ports and Port B ber ports of the two modules via an
appropriate multimode or single-mode ber 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 ber (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 ber must match the
reception (Rx) and transmission (Tx) at the opposite
end. For example, an 8430-1 should be connected to
an 8431-1.
