The appropriate “LNK” (link) LED is lit to indicate this. The Black Box media converter also sends out link pulses from its copper and fiber transmitters, but normally has no way of knowing whether the cable to the other device is intact and the link pulse

Chapter 4: Install the High-Density Media Converter System II Layer 2 Modules Regardless if there is a break in segment 1, 2 or 3, the link will drop on the switches at both ends. The link fault is passed through the media conversion and is observed at each end. It acts just like it would if the devices were directly connected.

Chapter 4: Install the High-Density Media Converter System II Layer 2 Modules WARNING Enable FiberAlert at the remote side of a media conversion only. Enabling it on both sides would keep both transmitters disabled indefinitely. By default FA is disabled. When enabled if, a fault occurs on the fiber line, affecting data in one direction, FA stops sending signal in the opposite direction. FXLL will act on this lack of signal, propagating the loss of like to the copper port when F

Chapter 6: Troubleshooting 6. 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. • To test a L2 by itself, first, have an

Chapter 8: Fiber Optic Cleaning & ESD Precautions 8. 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-d
