Chapter 2: Overview 2. Overview 2.1 Introduction Use the PoE PSE Media Converter, 10/100/1000BASE-T to 1000BASE-SX/LX to connect two types of network segments easily and inexpensively. It complies with IEEE 802.3af power over Ethernet (PoE) standard. The AC-powered PoE media converter is power sourcing equipment (PSE) that combines data received over a twisted-pair link with -48 VDC, providing power to an IEEE 802.3af-powered device (PD) over the existing CAT5 UTP cable. The media converter

Chapter 4: Link Fault Passthrough 4. Link Fault Passthrough This converter supports link fault passthrough (LFP). Link status on one port is sent to the other port to identify the remote nodes. If the twisted-pair port is unplugged, the converter stops transmission on the fiber port. This causes the remote fiber node link to fail. LEDs indicate the link failure on both twisted-pair and fiber ports. If the fiber link fails, the converter restarts autonegotiation on the twisted-pair port but st
