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.
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.
- 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.

FX LinkLoss, TX LinkLoss, Link Fault Pass-Through, Far End Fault and FiberAlert iMcV-LIM modules include the troubleshooting features FiberAlert, TXLL, FXLL, FEF and LFPT that help locate silent failures on a network. Before attempting to install the module(s), understand how these features work and react to a specific network configuration. Link Integrity During normal operation, link integrity pulses are transmitted by all point-to-point Ethernet devices.
Link Fault Pass-Through (LFPT) Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and FX LinkLoss from both the local and remote iMcV-LIM modules. LFPT is enabled by turning on both FX and TX LinkLoss on both modules. This feature allows either end of the conversion to detect a link fault occurring at the other end of the media conversion chain. Regardless if there is a break in segment 1, 2 or 3, the link will drop on the switches at both ends.
FiberAlert and Far End Fault Modules ship from the factory with troubleshooting features disabled. Refer to the help file to enable/disable this feature. FiberAlert (FA) FiberAlert minimizes the problems associated with the loss of one strand of fiber. If a strand is unavailable, the IMC Networks device at the receiver end notes the loss of link. The device will then stop transmitting data and the link signal until a signal or link pulse is received.
FEF versus FA FEF is preferred when the devices at both ends of the fiber can interpret the FEF signal. This allows FEF to be turned on at both ends, which will engage the FEF regardless of which direction the fault occurs. (Please refer to diagram on previous page) For example if a fault should occur on segment 2 in the direction of segment 1 to 3, FEF would be engaged on the iMcV-LIM between segment 2 and 3. This would then send a signal back to the iMcV-LIM between segment 1 and 2.
Auto Negotiation on iMcV-LIM iMcV-LIM modules include the feature Auto Negotiation. When Auto Negotiation is enabled, the module negotiates as a 100 Mbps full-duplex device. If the connected device can operate at 100 Mbps full-duplex, a link is established. Auto Negotiation (DIP Switch #1) is enabled by default. If the twisted pair port on the other device does not have the ability to Auto Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto Negotiation must be disabled.
LED Operation Each iMcV-LIM module features diagnostic LEDs that provide information on features and ports. FEF Glows green when a fiber end fault is detected. TXLL Glows green when TX LinkLoss is enabled on the port. Blinks when a fault occurs on the copper port and actively disables the fiber port. LNK Glows green when fiber link is established. CONFIG CONTROL Blinks green when activity is detected. * DIS Glows amber when software is disabled on the TX port.
Installation Troubleshooting • During installation, first test the fiber and twisted pair connections with all troubleshooting features disabled, then enable these features, if desired, just before final installation. This will reduce the features’ interference with testing. • When working with units where the features cannot be disabled, establish both the twisted pair and fiber connections before the link LEDs will light.

Fiber Optic Cleaning Guidelines Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules. 1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to-diagnose problems in an installation. 2.
Electrostatic Discharge Precautions Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand alone units, containing electronic components. Always observe the following precautions when installing or handling these kinds of products 1. Do not remove unit from its protective packaging until ready to install. 2. Wear an ESD wrist grounding strap before handling any module or component.
