SAFETY AND WARNINGS
Elevated Operating Ambient: If installed in a closed cabinet, the operating ambient temperature of the rack environment
may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature specified by the manufacturer.
Reduced Air Flow: Installation of the equipment should be such that the amount of air flow required for safe operation
of the equipment is not compromised.
Mechanical Loading: Mount the equipment in the DIN rail so that a hazardous condition is not achieved due to uneven mechanical
loading.
Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings
when addressing this concern.

CHAPTER 2: OVERVIEW
2.1 INTRODUCTION
The Industrial PoE Media Converter (LGC5500A) is a cost-effective solution for conversion between 10/100/1000BASE-T(X)
and 100/1000BASE-X SFP interfaces, allowing you to extend communication distance using optical fiber. The device supports
MDI/MDIX auto detection, so you don’t need to use crossover wires. With a 10/100/1000BASET(X) P.S.E. (Power Sourcing
Equipment) port, the device can transmit electrical power up to 30 watts, along with data, to remote devices over standard
twisted-pair cable in an Ethernet network. It also supports LFP (Link Fault Pass-through). When one side of the link fails, the other
side continues to transmit packets and will wait for a response that never arrives from the disconnected side. LFP can be easily
enabled using the DIP switch. Once enabled, the link will shut down as soon as it is notified that the other link has failed, giving the
application software a chance to react to the situation.
The LGC5500A has a wide operating temperature range from -40 to +167° F (-40 to +75° C) and a wide voltage range between 50 to
57 VDC, so it is suitable for harsh operating environments.

This equipment generates, uses, and can radiate radio-frequency energy, and if not installed and used properly, that is, in strict
accordance with the manufacturer’s instructions, may cause interference to radio communication. It has been tested and found to
comply with the limits for a Class A computing device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial
environment. Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own
expense will be required to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate
the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio
Interference Regulation of Industry Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques
de la classe A prescrites dans le Règlement sur le brouillage radioélectrique publié par Industrie Canada.
