FCC Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a Class B computing device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial

environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the

instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to

cause harmful interference in which the user will be required to correct the interference at his own expense.

Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.

The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits. This digital apparatus does not exceed the Class B

limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de classe B

prescrites dans le Règlement sur le brouillage radioélectrique publié par le ministère des Communications du Canada.

About the iMcV-LIM

The iMcV-LIM is a Fast Ethernet module which provides a single conversion between 100Base-TX twisted pair and 100Base-FX/SX single-mode or multi-mode fiber. Each iMcV-LIM includes one RJ-45 connector and one pair of ST or SC fiber optic connectors, and/or an SFP port, which can support any fiber type. Models with Configuration Control are identified by a label on the faceplate of the module.

Also available in a single-strand fiber version, iMcV-LIM TX/SSFX and iMcV-LIM TX/SFP with Configuration Control allow two wavelengths to share one fiber strand — Full-Duplex data travels on different wavelengths, for example (1310 nm and 1550 nm) — doubling the capacity of fiber.

The iMcV-LIM is SNMP-manageable and can be installed into the modular, SNMP-manageable iMediaChassis, as well as the MediaChassis series, which are unmanaged.

Configuration Instructions

The iMcV-LIM has user-configurable features (e.g., FiberAlert (FA), TX LinkLoss (TXLL), FX LinkLoss (FXLL), Link Fault Pass-Through (LFPT) and Far End Fault (FEF)). Refer to the iMcV-Module DIP Switch configuration table for information on available features. Instructions for configuring both managed (via an SNMP-compatible management application like iView²) and unmanaged modules follow.

Installing an iMcV-Modules

The iMcV-Modules install in IMC Networks’ SNMP manageable iMediaChassis series or in any MediaChassis.

NOTE

All modules are hot-swappable.

To install an iMcV-Module:

Remove the blank bracket covering the slot where the module is to be installed by removing the screws on the outside edges of the bracket. Slide the iMcV-Modules into the chassis, via the cardguides, until the module is

2. seated securely in the connector.

Secure the module to the chassis by tightening the captive screw. Save any “blanks” removed during installation for future use if the configuration

4. requirements change.

Managed Modules

To manage one or more iMcV-LIM(s), an SNMP agent must be present in the chassis. To configure Managed Modules, install the module first, and then configure using the management software.

Fiber type, serial number and date code are now loaded into the NVRAM during manufacturing. This is viewed only via iView² software, within the modules details.

Requirements:

• SNMP Firmware version C2

• iView² 1.8.6 or higher

NOTE

For iMcV-LIM modules without Configuration Control, management software overrides any hardware settings (e.g., jumper, switch, etc.); a module must be configured so that it will be managed via the software.

iMcV-LIM and Configuration Control

The iMcV-LIM with SFP offers Configuration Control; a label on the front faceplate identifies the unit as such. Configuration Control has been implemented to assist the end user by retaining the latest configuration regardless of how that configuration was implemented (via DIP Switch settings or SNMP).

Historically, SNMP would override DIP Switch settings. If changes are made via DIP Switch settings, then hardware settings determine the configuration of the board. If changes are made to the module via iView

, the SNMP settings determine the

configuration of the board.

Utilizing Configuration Control, the end user has three conditions under which the configuration of the iMcV-Module may be impacted:

• Installing an iMcV-LIM into a chassis already loaded with iMcV-Modules or

replacing an iMcV-LIM

The iMcV-Module will transfer its saved configurations. The iMcV-LIM will not override the module’s configuration.

• Replacing the same type of iMcV-Module

If the DIP Switch settings are the same as the settings on the removed iMcVModule, the iMcV-LIM determines the configuration settings.

If the DIP Switch settings are different, then the configuration of the module is determined by the DIP Switch settings. (The settings are forwarded to the iMcV-LIM and the value is saved.)

• Installing a new model of iMcV-Module

If another type of module is installed into the same slot in a chassis, the iMcV-LIM clears the memory of the previous configuration for that slot; the settings of a new module are adopted and stored in the iMcV-LIM

The SNMP Write Lock switch does not impact any iMcV-Module or iMcV-Module with Configuration Control. Removing and installing a new SNMP Management Module will no longer impact these modules either. However, if there is a mixture of iMcV-Modules with and without Configuration Control, the Write Lock Switch and a new SNMP Management Module must be taken into consideration.

If the command cleandb is applied to an SNMP Management Module, all the settings for the modules will be removed, but the Configuration Control modules will still be based on the last change made, while those without Configuration Control will be set to their default settings.

NOTE

If the end user has a mixture of standard iMcV-Modules as well as Configuration Control iMcV-Modules, it is important to understand how SNMP and DIP Switches will impact the cards depending on their capability. Standard iMcV-Modules cannot be upgraded to Configuration Control capability, so it is strongly recommended to set the DIP Switches on the modules and then configure them via software to match the same settings.

Unmanaged Modules

Before installing, configure the iMcV-LIM modules for desired features. The table below indicates the available features and settings for the iMcV-LIM modules.

After configuring the DIP Switches for the desired settings, install the module and connect the appropriate cables (refer to Installing an iMcV-LIM section for more information).
