OVERVIEW:

The iConverter 2Fx is a two-port, 100BASE-FX to 100BASE-FX manageable optical switch that retimes and regenerates the fiber optic signal. It performs error checking and MAC address learning, and can be used to daisy chain chassis for distributed networking.

The 2Fx supports Half-Duplex and Full-Duplex modes for easy attachment to hubs, switches and workstations.

In addition to the two fiber optic ports, the 2Fx can also use its two 10/100 backplane ports to connect to adjacent modules and accommodate flexible network configurations like in-band management and multi-module configurations.

The have backplanes that facilitate connectivity between adjacent modules.

The 2Fx can be used in an unmanaged or managed fashion. When unmanaged, it can be installed in an iConverter Chassis without a Network Management Module (NMM) or or 10/100M module must be installed in the same chassis.

Advanced Features:

The 2Fx features Port VLAN and Tag VLAN, which allow complete control of traffic flow between both fiber ports and chassis backplane ports on a module, and Port Access Control, which facilitates enabling and disabling of individual ports. The 2Fx also supports individual port bandwidth control and reporting of MIB statistics.

Note that using the Advanced Features listed above requires the use of the NMM or 10/100M and the

NetOutlook™ Management Software, or third-party

SNMP management software or Telnet. For more information on using and configuring the

Advanced Features, please refer to the

NetOutlook

Management Software user manual.

PORT STRUCTURE:

Using a 4-port switch design, the 2Fx features two frontplane fiber ports and two 10/100 Ethernet backplane ports (A and B) that can connect to adjacent modules within the same chassis.

When the 2Fx’s A and B ports are enabled (using the “A EN” and “B EN” DIP-Switches), they connect to the slots on the left and right sides of the 2Fx module via the chassis’ “A” and “B” backplane links. When other switchbased

iConverter modules with backplane port connections

such as a 4-port 10/100 switch module (4Tx) and an NMM are installed in adjacent slots, they can be connected via the chassis’ backplane to the 2Fx to facilitate a multimodule configuration.

2Fx Application Example:

Fig. 1 In-Band Managed 2Fx Application

Fig. 1 depicts a chassis with three modules plugged into three of its adjacent backplane slots. The modules are connected to the backplane using the A and B backplane 10/100 Ethernet ports. The modules in adjacent slots are connected to each other via the “A” and “B” backplane links. The 2Fx in Slot 2 connects to Slot 1 using the “A” backplane link and to Slot 3 using the “B” backplane link.

In this example, the module in Slot 1 is a Network Management Module (NMM) and it connects via its “A” backplane link to the 2Fx in Slot 2, facilitating in-band management (via the fiber uplink). The module in Slot 3 is a 4Tx and it connects via its “B” backplane link to the 2Fx facilitating a 4-port 10/100 Ethernet switch with two fiber uplinks.

This example shows how the 2Fx can be used as a traditional

managed or unmanaged media converter to create flexible and effective network switch configurations. To find out about individual chassis “A” and “B” backplane links, refer to the specific chassis’ user manual.

LINK MODES:

In order to accommodate different user needs, the 2Fx supports four different linking modes.

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 P1 transmits a “Link” regardless of the P2 receiving a “Link” [Fig. 2(a) & (b)].

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 P1 transmits a “Link” only when receiving a “Link” at the P2 [Fig. 2(c)].

In “Remote Fault Detection” (RFD), the fiber port transmit 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)].

In “Remote Fault Detection + Link Propagate” (RFD+LP), the P2 transmits a “Link” signal only when receiving a “Link” at the P1. The P1 transmits a “Link” only when receiving “Link” signals both at the P1 and the P2. As a result, P1 faults (no “Link” received at the fiber) are looped-back to the network core and propagated to the edge [Fig. 2(e)].

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