About the IE-iMcV-MediaLinX TX/SFP NOTE Unless noted otherwise, all references to the IE-iMcV-MediaLinX TX/SFP in this manual are also applicable to the iMcV-MediaLinX TX/FX. Configuration Control models are identified by a Config Control label and a unique part number. The SNMP manageable IE-iMcV-MediaLinX TX/SFP module provides a single conversion between 10/100 Base-T twisted pair and 100 Base-SX/FX fiber.
Managed Modules To manage one or more IE-iMcV-MediaLinX TX/SFP Modules, an SNMP agent must be present in the chassis: The iMediaChassis series requires an SNMP Management Module. To configure Managed Modules, install the module first, and then configure using the management software. Module Details will provide information such as serial number, date code and part number as well as product-specific features.
The SNMP Write Lock switch does not impact any iMcV-Module or IE-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.
FX LinkLoss, TX LinkLoss, Link Fault Pass-Through, FiberAlert and Far End Fault IE-iMcV-MediaLinX TX/SFP modules include the troubleshooting features such as TXLL, FXLL, LFPT, FA and FEF 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.
FX LinkLoss (FXLL) FX LinkLoss is a troubleshooting feature. When a fault occurs on the fiber segment of a conversation, FX LinkLoss detects the fault and passes this information to the twisted pair segment. If a media converter is not receiving a fiber link, FX LinkLoss disables the transmitter on the media converter’s twisted pair port. This results in a loss of link on the device connected to the twisted pair port, and the FXLL LED will blink. TX LinkLoss (TXLL) TX LinkLoss is a troubleshooting feature.
FiberAlert (FA) By default FA is turned off. When enabled, if a fault occurs on the fiber line, affecting data in one direction, FA stops sending a signal in the opposite direction. FXLL will act on this lack of signal propagating the loss of like to the copper port when FXLL is enabled. 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.
FA is used when connecting to a device that does not support FEF. If an FEF signal is sent to a device that does not support FEF, the device acts as if there is still a good connection. The FEF signal is mistaken for data. FA works similar to FEF, in that when there is a fault in one direction of the fiber, it acts on the fiber in the opposite direction. But unlike FEF, FA sends no signal. Because of this, FA can not be enabled on both ends.
Additional IE-iMcV-MediaLinX TX/SFP Features Selective Advertising 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 are desired, IMC Networks recommends using Selective Advertising, rather than Force Mode, when connecting to devices that only use Auto Negotiation.
AutoCross Feature for Twisted Pair Connection All twisted pair ports on the IE-iMcV-MediaLinX TX/SFP include AutoCross, a feature that automatically selects between a crossover workstation and a straight-through connection depending on the connected device. LED Operation Each IE-iMcV-MediaLinX TX/SFP Module features diagnostic LEDs that provide information on features and ports. Twisted Pair LEDs TXLL Glows when TX LinkLoss is enabled.
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 connecting to an end device, such as another switch, be sure to use the same configuration on its port as well as the IE-iMcV-MediaLinX TX/SFP.
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.
