With LFP (Link Fault Propagation) support it allows the administrator to easily diagnose link faults on their network. If the Copper or Fibre link fails, the converter forces the link status of the connecting device to also fail. The POE120 Series media converters are fully compliant to the IEEE 802.3af standard. The converters advanced auto-sensing algorithm allows the unit to draw power from any IEEE 802.3af Power Sourcing Equipment (PSE) device (POE100 Series Converter, or PoE Switch) or Power over Ethernet Injector. It also supports high levels of safety support with short circuit protection and power-in auto-detection. The POE120 series converters can be powered from either a standard plug pack or a PSE device. 2.

Checklist Before you start installing the POE converter, please verify that the package contains the following items. -The POE120 Series Converter -CD containing this manual Please notify your sales representative if any of the above items are missing or damaged. 4. Installing the Converter 4.1 POE120 converter connected to a Power Sourcing Equipment Device (PSE) 1. Connect the copper cable to your IEEE 802.3af compliant PSE device. The POE120 can also work as a standard media converter and connect to a non POE device. (power supply is optional) 2. Connect the fibre cable to your connecting device. Note: - Please make sure that the 802.3af power is being supplied from a PSE device to the PD Media Converter. - In case there is no 802.3af PSE available or the PSE device power fails, you may install an AC-DC adapter as a backup solution. Do not connect the PSE Copper port and a AC-DC adapter at the same time. (the power options are not designed in a redundant configuration) Default: Auto TP Port Auto or Force setting, see figure 11. S1-Bit 1 Attach Cat. 5 cable to the copper port and ensure the cable run is not over 100m in distance. The Copper port supports Auto MDI-X, therefore there is no need to use a cross-over cable when connecting to a switch. Fibre Default: 100FDX Port ”100FDX”/”100HXD” setting, see figure 11.

WDM Single Fibre Model The POE120 Series media converter has an optional Wavelength Division Multiplexing (WDM) Model that can transport bi-directional full duplex signals over a single fibre simultaneously. Single Fibre Model TX, RX Wavelength 1310nm Single Mode 20Km TX (Transmit) 1310nm RX (Receive) 1550nm 1550nm Single Mode 20Km TX (Transmit) 1550nm RX (Receive) 1310nm Note: The 1310nm and 1550nm models must be installed in pairs, i.e., install 1310nm model at one end and the 1550nm model at the other end. 6. Link Failure Propagation The POE120 Series media converters support Link Failure Propagation (LFP). If the Copper port is unplugged, the converter stops transmission on the fibre port. This causes the remote fibre node link to fail as well. The LED’s on the converter will now show link failure on both the copper and fibre ports. If the fibre link fails, the converter restarts auto-negotiation on the copper port but always stays in the link failure state. This causes the remote copper node link to fail as well. The LED’s on the converter will now show link failure on both the copper and fibre ports. Refer to Fig. 7 shown below for the normal status when link is active. Also refer to Fig. 8 and Fig. 9 for the LED status when copper Cable A, Fibre Cable B or Fibre Cable C fails. Note: The Link Failure Propagation (LFP) function only takes effect when S1-Bit4 (see Fig. 11) is enabled. When S1-Bit4 is disabled the media converter will function normally. AB 10/100 Switch LFP .
