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 includes PD signature sensing and power monitoring. It also features overcurrent protection, undercurrent
detection, and fault protection input. The Link Fault Passthrough (LFP) allows the media converter to monitor both the fiber and
copper RX ports for loss of signal. In case of a loss of RX signal on one media port, the converter will automatically disable the TX
signal to the other media port, passing through the link fault. Far End Fault (FEF) enables the converter to stop sending link pulse
to the link partner once a loss of the fiber RX signal is encountered. Then the link partner will synchronously stop sending data.
FEF prevents loss of valuable data transmitted over an invalid link.

• LPS500A-MM-SC: PoE PSE Media Converter, 10/100/1000BASE-T to 1000BASE-SX, SC connectors, multimode fiber

Chapter 3: Installation
3. Installation
3.1 Connecting Hardware
The 10/100/1000BASE-T PoE PSE to 1000BASE-X Media Converter requires no software configuration. To install the media
converter, follow the steps below:
1. Connect the PSE media converter to an AC power source.
2. Connect a PoE/PD device to the PSE/TP port on the media converter using the appropriate twisted-pair cable. The media
converter can also work as a standard media converter when PoE is disabled.
3. Connect the FX port to a fiber network using the appropriate fiber cable.
WARNING: Verify that the AC input conforms to your country’s AC power requirement before inserting the power plug.

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 stays in the link failure state. This causes
the remote twisted-pair node link to fail. LED also indicates the link failure on both twisted-pair and fiber ports.
Refer to Figure 4-1 for the normal status when the link succeeds. Refer to Figure 4-2 and Figure 4-3 for the error status when TP
Cable A, Fiber Cable B, or Fiber Cable C fails to connect.
NOTE: LFP function only takes effect when S1-2 (see Figure 2-3) is enabled. Disabling S1-2 will turn LFP off.
