Introduction

About FiberLinX

FiberLinX from IMC Networks is an IEEE 802.3 compliant, SNMP-

manageable media converter/LAN extender/Ethernet bridge that can be

managed remotely. FiberLinX is designed to convert between 10 Mbps

Ethernet twisted pair (10Base-T) and 10 Mbps Ethernet (10Base-FL) single-

mode or multi-mode fiber optic cabling.

Each FiberLinX features the following three ports:

10Base-T data port

10Base-FL data port

10Base-T port specifically

for SNMP traffic (i.e., the

management port).

NOTE: Although the

management port is designed to

accept SNMP traffic, ANY port on the FiberLinX Module can be configured to

serve as the SNMP management port.

NOTE: The twisted pair management port is not designed to handle data

traffic, and therefore should NOT serve as a redundant twisted pair port.

The primary advantage of FiberLinX is that it allows the administrator to

completely monitor and manage fiber traffic between switches and routers

while remaining isolated from the remote (or customers) network.

About FiberLinX Modules

FiberLinX Modules can be installed into any IMC Networks

PowerChassis/100-Series. The following versions of FiberLinX Modules are

available:

FiberLinX  10Base-T twisted pair and 10Base-

FL 850 nm multi-mode fiber; includes

two RJ-45 connectors and one pair ST

or SC connectors.

FiberLinX 1300  10Base-T twisted pair and

10Base-FL 1300 nm multi-mode fiber;

includes two RJ-45 connectors and one

pair ST or SC connectors.

FiberLinX-SingleMode  10Base-T twisted pair

and 10Base-FL 1300 nm single-mode

fiber; includes two RJ-45 connectors

and one pair ST or SC connectors.

FiberLinX-SingleMode/PLUS  as above with

higher power budget.

How FiberLinX Works

Each port on the FiberLinX includes its own MAC Address. The movement

of data from one port to another is

accomplished via packet switching.

The destination address of each

Ethernet packet entering the

FiberLinX is checked to determine

whether it is a management packet

or a downstream data packet, and

is switched appropriately. Packets

not addressed for management

ports are sent through to the

network. Similarly, management

packets are switched internally to

the management engine and are

not forwarded.

More information about how FiberLinX works can be found on the IMC

Networks Web site at www.imcnetworks.com.

Hardware Installation

Installing a FiberLinX Module involves the following steps:

1) Configuring the FiberLinX Module via its eight-position Dip

switch for the following:

lHalf/Full Duplex setting (data ports only),

ldesignating the management traffic port,

lhost/remote or standalone operation;

2) Installation of a PowerChassis/100-Series chassis;

3) Installation of the FiberLinX Module into the above-mentioned

PowerChassis; and,

4) Selecting a crossover or pass-through connection for the twisted

pair data port.

Configuring FiberLinX Modules

FiberLinX Modules have an eight-position Dip switch, located at position

S2 (shown below), for configuring the module.

Figure 2.1 Dip Switch Location on FiberLinX

(default settings shown)

2.1

All manuals and user guides at all-guides.com

The following table shows the function for each of the eight Dip switches

on FiberLinX. Refer to the section on each feature for specific configuration

information.

Switches 1 & 2: Fiber Optic Type

These Dip switch settings are configured at the factory and should NOT

be changed in the field.

Switches 3 & 4: Selecting Duplex Mode

Each data port on FiberLinX can operate in either Half-Duplex (HDX) or

Full-Duplex (FDX) Mode. (NOTE: The Twisted Pair management port is

ALWAYS Half-Duplex.) You will need to set the duplex mode of these ports

depending on the capabilities of the connected hardware.

FiberLinX is shipped from the factory with HDX selected on each data port

(i.e., Dip switches 3and 4in the OFF position). Select FDX for the fiber

data port by setting Dip switch 3to ON. Select FDX for the twisted pair data

port by setting Dip switch 4to ON.

Switches 5 & 6: SNMP Management Traffic

Although FiberLinX provides a twisted pair port solely for management

traffic, you can configure FiberLinX to accept SNMP management traffic from

any of its three ports. There are four different ways you can configure

FiberLinX to accept (or not accept) SNMP management traffic. Only one

source for SNMP management traffic can be active at any time, and only the

SNMP management traffic directed to the modules IP address will be

accepted.

FiberLinX is configured at the factory to accept SNMP management traffic

from the twisted pair data port (i.e., Dip switch 5ON, Dip switch 6OFF).

You can change this setting by adjusting Dip switches 5and 6. The

following table shows the switch settings for each configuration.

Switches 7 & 8: Configuring FiberLinX as a Host, Remote

or Standalone Unit

When two FiberLinX units are paired with one another, each FiberLinX

unit can be configured to be either a Host unit or a Remote unit. As a Host,

FiberLinX requests management information from any attached remote unit

and displays that information, along with its own, upon SNMP query. As a

Remote, FiberLinX will not respond to requests for management information

from an attached unit. In single installation, the sole FiberLinX should be

configured as standalone unit (factory default). Following is a table showing

the Dip switch configurations for each setting. Please see Chapter 4 of this

guide for possible installations and their related Host, Remote and

standalone Dip switch settings.

Configure FiberLinX to be a Host unit by setting Dip switch 8to ON.

Configure FiberLinX to be a Remote unit by setting Dip switch 7to ON.

FiberAlert

Since media converters are a transparent link in a network, FiberLinX

features FiberAlert, a troubleshooting feature that assists in pinpointing link

faults between media conversion products. If a media converter is not

receiving a fiber link, FiberAlert disables the media converter's fiber

transmitter, thus mirroring the link status of the opposite end of the fiber.

Both fiber link LEDs on either side of the devices should extinguish, alerting

you to the fault.

NOTE: FiberAlert should only be activated on one side of a media

conversion.

More information on FiberAlert can be found on the IMC Networks Web

site at www.imcnetworks.com/to-fa.htm.

Installing a FiberLinX Module

Once you configure a FiberLinX Module, it is ready to be installed in a

chassis. You can install a FiberLinX Module into any IMC Networks

PowerChassis/100-Series chassis (e.g., PowerChassis/101, etc.). FiberLinX

Modules may be safely installed or removed with power on (i.e., FiberLinX

Modules are hot-swappable). Please read the electrostatic discharge

precautions on page 5.1 of this manual before proceeding

NOTE:FiberLinX Modules should be installed into a PowerChassis

only AFTER the PowerChassis has been installed. Please see the

installation guide included with your chassis for assistance in installing

the chassis.

PowerChassis come with blank brackets covering the slots where the

modules are to be installed. To install a FiberLinX Module, remove the blank

bracket by loosening the screws located on the outside edges of the bracket.

Slide the FiberLinX Module into the chassis until the module is seated

securely in the connector. Secure the module to the chassis by tightening

the captive screws.
