iMcV-LIM ABOUT 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.
iMcV-LIM 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.
iMcV-LIM 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.

iMcV-LIM FX LINKLOSS, TX LINKLOSS, LINK FAULT PASS-THROUGH, FAR END FAULT, 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.

iMcV-LIM 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.
iMcV-LIM 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 B+B SmartWorx device at the receiver end notes the loss of link.
iMcV-LIM 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.

iMcV-LIM LED OPERATION iMcV-LIM module diagnostic LEDs provide information on features and ports. 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.
iMcV-LIM TROUBLESHOOTING - INSTALLATION • 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.
