About the iMcV-Gigabit The SNMP manageable iMcV-Gigabit module provides a single conversion between 1000 Base-T twisted pair and 1000 Base-SX/LX fiber. Each iMcV-Gigabit includes one RJ-45 connector and one pair of SC fiber optic connectors. iMcV-Gigabit modules install into any modular, SNMP manageable iMediaChassis, as well as the MediaChassis series, which is unmanaged.
Unmanaged Modules Before installing, configure the iMcV-Gigabit Module for desired features. The table below indicates the available features and settings for the module. After configuring the switch for the desired settings, install the module and connect the appropriate cables. For further information, refer to the Installing an iMcV Module section.
LinkLoss, FiberAlert and Link Fault Pass-Through iMcV-Gigabit modules include the troubleshooting features FiberAlert, TXLL, FXLL 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. ** WARNING ** Installing modules without understanding the effects of LinkLoss and FiberAlert can cause functioning units to appear flawed or even non functional.
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. The result is that the link LED on BOTH sides of the fiber connection will go out indicating a fault somewhere in the fiber loop.
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-Gigabit 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. FiberAlert can also be enabled at the main site.
Additional Gigabit Features Preferred/Forced Mode The iMcV-Gigabit module also includes a Preferred/Forced Modes for Master/Slave negotiation. Preferred Mode helps determine whether the module should act as a Master or Slave. Forced Mode should typically only be used when connecting to some legacy switches, or when there is difficulty establishing a link. The default is Preferred Mode (S1-1 is ON). This feature is hardware configurable only.
AutoCross Feature for Twisted Pair Connection All twisted pair ports on the iMcV-Gigabit includes AutoCross, a feature that automatically selects between a crossover workstation and a straight-through connection depending on the connected device. LED Operation Each iMcV-Gigabit Module features diagnostic LEDs that provide information on features and ports. iMcV-Gigabit w/LFPT LNK/ ACT Glows green when a twisted pair link is established. Blinks green when data is detected on the 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. If using a high powered device (which is designed for long distance installations) for a short distance installation, the fiber transmitters may overdrive the receivers and cause data loss.

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.
