CHAPTER ONE:

INTRODUCTION

About the iMcV-FiberLinX

The iMcV-FiberLinX connects two remote networks over a fiber optic line

and allows administrators to observe both the end-points and the fiber link

between them as a single management entity and not as separate networks.

No host management traffic is visible to the remote or customer network

nor is access to the customer network required, guaranteeing end-to-end

data integrity.

The iMcV-FiberLinX includes one 100 Mbps fiber port (OPTICS), one

10/100 twisted pair data port (DATA) and an additional 10/100 twisted pair

port (EXT MGMT) utilized for managing traffic. Twisted pair ports auto-

negotiate or can be set manually for 10 or 100 Mbps, and half or full-

duplex. The fiber port operates at 100 Mbps; duplex mode can be set man-

ually.

The iMcV-FiberLinX is 802.1Q VLAN compatible, supporting a full-range of

VLAN IDs, and offers a 2-tier queue for differential prioritization. The

iMcV-FiberLinX also includes the LinkLoss and FiberAlert features for trou-

bleshooting, loopback testing functionality, bi-directional bandwidth con-

trol, and optional protection against Broadcast storms. SNMP-manageable,

the iMcV-FiberLinX is easy to configure with the GUI-based iView² applica-

tion as well as the iConfig utility.

Single-strand fiber versions of the iMcV-FiberLinX allow two wavelengths to

share one fiber strand — Full-Duplex data travels on different wavelengths

(1310 nm and 1550 nm) — doubling the capacity of installed fiber.

iMcV-FiberLinX modules install in any iMediaChassis, iMediaCenter

chassis, and MediaChassis.

NOTE

Refer to Chapter Two: Product Application for information on implementing

the iMcV-FiberLinX into a network.

About iView²

iView² is a network management application for IMC Networks intelli-

gent networking devices. It features a graphical user interface (GUI) and

gives network managers the ability to monitor and control IMC Networks'

products. The application is available in several versions and can also func-

tion as a snap-in module for HP OpenView

Network Node Manager. See

the IMC website for information on which version of iView² to select. Refer

to the help files for iView² and the iMcV-FiberLinX for information regard-

ing configuring and managing the iMcV-FiberLinX.

A BOUT IC ONFIG

iConfig is an in-band utility created by IMC Networks, used for SNMP

configuration for IMC Networks’ SNMP-manageable devices. iConfig can:

• set an IP address, subnet mask and default gateway

• define community strings and SNMP traps

In addition to the above functions, iConfig offers an authorized IP

address system and access restriction to MIB groups supported by IMC

Networks manageable devices. These extra layers of security do not affect

SNMP compatibility.

iConfig can also be used to upload new versions of the system software

and new MIB information. It also offers diagnostic capabilities for faster

resolution of technical support issues. iConfig version 1.4 or above MUST

be used for PROM updates. HubControl32 and previous versions of

iConfig will not work. iConfig works with the following platforms:

• Windows 98™ • Windows NT™ • Windows 2000™ • Windows XP™

In addition to being included with the Windows version of iView²,

iConfig is also available as a standalone application. (Windows 98 users

must use the standalone version of iConfig.) Both applications are includ-

ed on the iView² CD or can be downloaded from the IMC website. For

information regarding the use of iConfig, refer to the iConfig help file

included with iConfig.

About Features and Configuration

The iMcV-FiberLinX offers a full feature set including Auto-Negotiation,

Selective Advertising, FiberAlert, AutoCross, read/write VLANs, SNMP

management, bandwidth control, and loopback testing. Some features are

hardware configurable only, while others can only be configured through

software or via a serial port, Telnet session, iConfig or DHCP client.

LED Operation

The iMcV-FiberLinX features several diagnostic LEDs, which function as fol-

lows:

FAR CPU UP (FCU):

• Host: Glows green when the remote (or far) end

is detected.

• Remote: Glows green when is configured as a

Remote.

• Standalone Unit: LED remains OFF.

SNMP: Blinks green with SNMP activity.

EXT 100: Glows green when the EXT MGMT port is

operating at 100 Mbps.

Data 100: Glows yellow when the TX DATA port is operating

at 100 Mbps.

LNK/ACT (There are two sets of these LEDs, which mirror

each other):

• Glows green when a link is established on the

port.

• Blinks green during data activity on the port.

FDX/COL:

• Glows yellow when the port is operating in

Full-Duplex mode.

• Blinks yellow when collisions occur on the port.

FA: Glows green when FiberAlert is enabled

(This Feature is not available on single-strand

fiber versions. The LED will remain OFF).

FAR TX LINK (FTL):

• Host: Glows green when a link is established on

a remote (far-end) TX DATA port.

Remote: Glows green when configured as a Remote.

• Standalone Unit: LED remains OFF.

CHAPTER TWO:

PRODUCT APPLICATION

Here are some things to consider before installing the iMcV-FiberLinX into

a network:

• How many iMcV-FiberLinX units will be used.

• How will the iMcV-FiberLinX be managed?

• Will VLAN IDs be defined?

How many iMcV-FiberLinX units will be used.

• Two for a Host/Remote application (one at each end)

• One for a single solution application

How will the iMcV-FiberLinX be managed?

The iMcV-FiberLinX can be managed from any of its three ports or a com-

bination thereof. Using the EXT MGMT port separates management traffic

and provides a higher level of security.

Will VLAN IDs be defined?

To provide VLAN traffic with specific tags on any/all of the ports (as

shown), disable Transparency Mode and define VLAN IDs. For both tagged

and

untagged VLAN traffic, enable Transparency Mode.

Figure B: VLAN Traffic on All Ports

Application Examples

The following are application examples for both VLAN and non-VLAN

environments. These are only examples; other implementations are possi-

ble. Contact IMC Networks Technical Support at techsupport@imcnet-

works.com. for configuration assistance.

There are three general types of installations:

• Transparency Mode with untagged and tagged packets;

(VLAN IDs are not defined)

• Non-VLAN environment with only untagged packets;

• VLAN environment using ONLY defined VLAN IDs;

(Transparency Mode is disabled)

Host/Remote Application — Transparency Mode Enabled

In Host/Remote applications, where Transparency mode has been

enabled and management is disabled on the DATA port, both tagged and

untagged traffic will be present. VLAN IDs do not need to be defined,

though a specific VLAN ID for management can be set. In this application,

there is also the option of setting the devices for Secure Mode.

NOTE

VLAN IDs can be any number between 1 and 4,094.

NOTE

Some diagrams may show TX or FX for ports, rather than the names shown on the

unit. In this case, TX = DATA port and FX = OPTICS port. The management port

is typically shown as EXT MGMT.

Figure C: Dual FiberLinX Application with Transparency

NOTE

In an application where management is handled through the DATA port (i.e. not

using the EXT MGT port) on the Host unit, turn management OFF on the EXT port,

and enable management on the DATA and OPTICS ports on the Host. Also,

enable management only on the Remote’s FX Data port. On both units,.answer

NO when asked if a VLAN tag is required on the EXT MGMTport.

Non-VLAN Environment

Host/Remote Application— No VLAN IDs

When deploying iMcV-FiberLinX in pairs and NOT assigning VLAN IDs,

use the iMcV-FiberLinX’s Basic Mode. This mode includes a pre-defined

group of settings, providing for easy configuration.

Figure D: Dual FiberLinX Application without VLAN IDs

NOTE

The Remote iMcV-FiberLinX must have SNMP enabled on the OPTICS port for the

Host site’s iMcV-FiberLinX to communicate with it.

CHAPTER THREE:

INSTALLATION

To install the iMcV-FiberLinX in an iMediaChassis, iMediaCenter chassis

or any MediaChassis, remove the blank bracket covering the slot, if neces-

sary, where you will be installing the module. Then, slide the module into

the chassis, via the cardguides, until the module is seated securely in the

connector. Secure the module to the chassis by tightening the captive

screw.

Connect the iMcV-FiberLinX to the desired devices, making sure to use

the port(s) labeled OPTICS for the long-haul fiber run.

The iMcV-FiberLinX includes on-board SNMP logic. When installed in

an IMC Networks SNMP-manageable chassis, the iMcV-FiberLinX module

draws power from the chassis only (i.e. it is an independently managed

module). When installed in an iMediaChassis, the iMcV-FiberLinX can also

be managed via the chassis using the Unified Management Agent (UMA).

Please refer to the UMA Help Files for more information.

If not using UMA, an IP Address will need to be assigned to the iMcV-

FiberLinX after installation. Refer to the section on assigning an IP Address.

NOTE

Since single-strand fiber products use optics that transmit and receive on two

different wavelengths, single-strand fiber products must be deployed in pairs or

connected with two compatible IMC Networks single-strand fiber products.

For example, connect iMcV-FiberLinX, TX/SSFX-SM1310-SC (which has 1310

xmt and 1550 rcv) to a product which has 1550 xmt and 1310 rcv, e.g. iMcV-

LIM, TX/SSFX-SM1550-SC. The two connected products must also have the

same speed and distance capabilities (i.e. both are single-mode [20km] or both

are single/PLUS [40km]).

Using the EXT MGMT Port as a Serial Port

Although the iMcV-FiberLinX does not include a DB-9 serial port, the

supplied RJ-45 to DB-9 adapter can be used on the EXT MGMT port to

perform serial port configuration. This adapter uses an IBM-compatible

DB-9 serial connector.

To connect the iMcV-FiberLinX to a terminal/computer, use a straight-

through (pin-to-pin) cable. (If the computer/terminal has a COM port using

a connection not compatible with a DB-9 connector, use the pin connec-

tion chart for reference in making a cable.) The cable length should be

under 50 ft. (15.24 m). Plug one end of the cable into the DB-9 connec-

tor on the iMcV-FiberLinX and the other into the appropriate port on the

computer/terminal. Set the computer/terminal for VT-100 emulation. The

serial port on the computer/terminal should be set for: 38.4K baud, 8 data

bits, 1 stop bit, no parity and no flow control.

CHAPTER FOUR:

HARDWARE CONFIGURATION

The following iMcV-FiberLinX features are hardware configurable only:

selecting management port, host/remote/standalone selection, and Half-

Duplex on the fiber port. The iMcV-FiberLinX includes the AutoCross fea-

ture which is hard-coded. You can also use the EXT MGMT port on iMcV-

FiberLinX as a serial port.

AutoCross Feature for Twisted Pair Connection

All twisted pair ports on the iMcV-FiberLinX include AutoCross, a feature

that automatically selects between a crossover workstation or pass-through

connection depending on the connected device. A MDI/MDIX button is

not required.

DIP Switch Settings

Before installing the iMcV-FiberLinX, set all features which are hardware-

configurable. Use the DIP switches, located at position S1 on iMcV-

FiberLinX, for configuration.

SWITCH FUNCTION DEFAULT

1 SNMP on EXT MGMT port ON

2 SNMP on DATA port OFF

3 SNMP on OPTICS port OFF

4 Half-Duplex on OPTICS port OFF

5 Factory Use — Do not change OFF

6 Basic Mode ON

7 Remote Unit OFF

8 Host Unit OFF

Figure H: Dipswitch Settings

Host/Remote and Standalone Units

Depending on the application, you can configure the iMcV-FiberLinX to

be a Host, Remote or Standalone unit.

When two iMcV-FiberLinX units are paired with one another, configure

one as a Host unit (set DIP switch 8

to ON) and the other as a Remote (set

DIP switch 7 to ON). As a Host, the iMcV-FiberLinX requests management

information from an attached remote unit and displays that information,

along with its own, upon SNMP query. As a Remote, the iMcV-FiberLinX

will respond to requests for management information from an attached

unit.

For single iMcV-FiberLinX installations, configure the sole iMcV-FiberLinX

as a Standalone unit (which is the factory default — DIP switches 7 and 8

both OFF).

SNMP Management Traffic

Although the iMcV-FiberLinX provides a twisted pair port solely for man-

agement traffic, SNMP management traffic can be received on any of its

three ports. More than one port can be used for management, or man-

agement can disabled on all ports, if desired.

Set DIP switch 1

to ON to use the EXT MGMT port for management.

Set DIP switch 2 to ON to use the DATA port for management.

Set DIP switch 3

to ON to use the OPTICS port for management.

Basic Mode

Basic Mode is a pre-configured combination of settings for Host/Remote

applications when NO user VLAN IDs are defined (VLAN functionality dis-

abled). Basic Mode must be used whenever connecting the iMcV-FiberLinX

to a “Legacy FiberLinX”. To enable Basic Mode set DIP switch 6 to ON.

Half-Duplex on the Fiber Port

The fiber port on iMcV-FiberLinX operates at 100 Mbps Full-Duplex. To

configure the port to operate in Half-Duplex set DIP switch 4 to ON.

CHAPTER FIVE:

MANAGEMENT

Assigning IP Information

In order for the iMcV-FiberLinX to utilize SNMP-management, IP config-

uration information (e.g., IP address, subnet mask, etc.) must be assigned

using iConfig (via iView²); the unit’s serial port or DHCP.

In addition to assigning an IP address and subnet mask, the former two

methods will also allow the creation of community strings, assignment of

access rights, configuration of traps and more. iConfig offers more options

than serial port configuration. After assigning iMcV-FiberLinX an IP address,

use iView² or another SNMP-compatible Network Management System

(NMS) to remotely configure, monitor and manage the iMcV-FiberLinX.

Software Configuration

The following iMcV-FiberLinX features are configurable ONLY via iView²:

FX LinkLoss, FiberAlert, Bandwidth Control and Loopback testing function-

ality. Auto-Negotiation, Selective Advertising, Force Mode and Flow

Control are configurable via iView² or a serial/Telnet session. Refer to the

iView² Help File for more information.

Auto-Negotiation, Duplex Mode and Speed

The twisted pair ports on the iMcV-FiberLinX auto-negotiate for speed

and duplex mode, while also providing the option of selectively advertising

or forcing the speed and duplex mode. The fiber port does not auto-nego-

tiate; it operates at 100 Mbps Full-Duplex (though this can be set to Half-

Duplex by changing the appropriate DIP switch). Configure features on

twisted pair ports via the management software.

NOTE

If not using UMA, an IP Address will need to be assigned to the iMcV-FiberLinX

after installation.

NOTE

To access the Remote site’s iMcV-FiberLinX and perform upgrades using iConfig,

Telnet, etc., assign the unit its own, unique IP address.

The iMcV-FiberLinX ships from the factory with Auto-Negotiation

enabled on the twisted pair ports. In this mode, the ports automatically

negotiate for speed and duplex.

The twisted pair ports on the iMcV-FiberLinX can also be manually set for

10 Mbps or 100 Mbps operation and for Half- or Full-Duplex (i.e. 10 Mbps

Full-Duplex, 10 Mbps Half-Duplex, 100 Mbps Full-Duplex or 100 Mbps

Half-Duplex).

Selective Advertising, when used in combination with Auto-Negotiation,

advertises only the configured speed and duplex mode for the twisted pair

port. If a specific speed and/or duplex mode is desired, Selective

Advertising should be used rather than Force Mode, when connecting to

devices that ONLY auto-negotiate.

Bandwidth Control

The iMcV-FiberLinX includes bi-directional bandwidth control.

Bandwidth can be independently set, in 32 Kbps increments, from the

transmitting Data port to the receiving port and vice versa in single iMcV-

FiberLinX solutions, and from the Host unit to the Remote unit and vice

versa in dual iMcV-FiberLinX applications (i.e. the bandwidth on the DATA

ports on both Host/Remote units is throttled).

FX LinkLoss and FiberAlert

The iMcV-FiberLinX includes the troubleshooting features FX LinkLoss

and FiberAlert. When a fault occurs on the fiber segment, FX LinkLoss

detects the fault and passes this information to the twisted pair segment.

This results in a loss of link on the remote twisted pair device.

FiberAlert minimizes the problems associated with the loss of one strand

of fiber. If a strand is unavailable, the iMcV-FiberLinX notes the lost link and

will stop transmitting data and the link signal until a signal or link pulse is

received. The result is that the link LED on BOTH sides of the fiber con-

nection will go out

indicating a fault some-

where in the fiber

loop. Using FiberAlert,

a local site administra-

tor is notified of a fault

and can quickly deter-

mine the location of a

cable fault.

Figure I: How FiberAlert Works

NOTE

Without understanding FX LinkLoss and FiberAlert, the iMcV-FiberLinX could

appear flawed or even malfunctioning.

Loopback Testing

The iMcV-FiberLinX includes Loopback testing functionality, which loops

back all frames arriving on the fiber port (except for the device’s manage-

ment traffic). This is helpful when troubleshooting standalone units. When

in Loopback mode, iMcV-FiberLinX drops the link on the twisted pair port.

Serial Configuration/Telnet Session

The following are instructions for serial configuration (including VLAN

configuration) and using Telnet sessions and DHCP.
