ABOUT THIS MANUAL

This document supports revision xx/19 or later of the

10/100. This revision incorporates the following

features:

1. Product support Flow Control via the on-board DIP-

switch selections.

2. Symmetrical Fault Detection has been added to the

module.

OVERVIEW

The

iConverter 10/100 converters support the IEEE

802.3 Ethernet standard and convert between Ethernet

10BASE-T or 100BASE-TX unshielded twisted pair (UTP)

and Fast Ethernet fiber 100BASE-FX. Models are

available for multimode (MM) and single-mode (SM)

dual fiber, and single-mode single-fiber.

The 10/100 supports Half-Duplex and Full-Duplex modes

and features a crossover UTP switch for easy

attachment to hubs, switches and workstations.

The 10/100 can be used as a standard two-port UTP to

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

backplane ports to connect to adjacent modules and

accommodate flexible network configurations like In-

Band management and multi-module configurations. The

iConverter 19-Module, 5-Module or 2-Module Chassis

have backplanes that facilitate connectivity between

adjacent modules.

The 10/100 can be used in an unmanaged or managed

fashion. When unmanaged, it can be installed in a chassis

without an iConverter Network Management Module (NMM)

iConverter 10/100M. To be managed, an NMM module

or 10/100M module must be installed in the same chassis.

PORT STRUCTURE

Using a 4-port switch design, the 10/100 features a

front-plane 10/100 UTP port, a front-plane 100Mbps

fiber port and two 10/100 Ethernet backplane ports (“A”

and “B”) that can connect to adjacent modules within

the same chassis.

When the 10/100 “A” and “B” ports are enabled (using

the “BPOEN” DIP-Switch), they connect via the chassis’

backplane to the slots on the left and right sides of the

10/100 module. When another switch-based module with

backplane port connections such as a second 10/100 or

an NMM is installed in an adjacent slot, it can be

connected via the backplane to the 10/100 to facilitate

a multi-module configuration.

Fig. 1: 10/100 Application Example

Fig. 1 depicts a chassis with three modules plugged into

three of its adjacent backplane slots. The adjacent slots

are connected via the backplane using the “A” and “B”

10/100 links. In this example, the 10/100 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.

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

Management Module (NMM) and it connects via its A

backplane port to the 10/100 facilitating “In-Band”

management (via the fiber uplink). The module on the

right is a 4-port 10/100 switch module (4Tx) and it

connects via its B backplane port to the 10/100 facilitating

a 5-port 10/100 Ethernet switch with a fiber uplink

configuration. This 3-module configuration provides an

effective 5-port 10/100 managed switch with a fiber

uplink configuration.

This example shows how the 10/100 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

user manual.

LINK MODES

In order to accommodate different user needs, the 10/100

supports four 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

only when receiving a Link at its other port. For example,

the UTP transmits a Link only when receiving a Link at

the fiber port [Fig. 2(c)].

In Remote Fault Detection + Link Propagate (RFD+LP),

the UTP port 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

received at the fiber) are propagated forward and looped

back for fault reporting at both the network core and the

customer location [Fig. 2(d)].

In Symmetrical Fault Detection (SFD), the UTP port

transmits a Link signal only when receiving a Link at

the fiber port. The fiber port transmits a Link signal

only when receiving a Link signal at both 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 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. A blinking fiber

link LED on a converter indicates a fault of the transmit

fiber or UTP cables of that converter [Fig. 3(e)].

NOTE: Connecting two converters with both set to

RFD mode is not supported and will cause a lockup.

NOTE: Converters in SFD mode must be deployed

in pairs.
