Power over Ethernet (PoE Conforming To IEEE 802.3af)
Power over Ethernet (PoE) is a technology for supplying network-enabled devices with power via an 8-wire
Ethernet cable. The main advantage of Power over Ethernet is that no additional power cable is required, making
Ethernet devices easy to install in hard-to-reach places or in places that are not equipped to handle numerous
cables. This can significantly reduce installation costs, while also increasing the reliability of the connected
devices by providing a central uninterruptible power supply (UPS).
Caution
The maximum length of the Ethernet cable for supplying power is
100 m
.
Care And Maintenance
Clean the NPA-PoE Set using a slightly moistened soft cloth, making sure that no liquid is allowed to enter. Never
use aggressive cleaning agents or cleaning agents with abrasive particles (scouring agent). Make sure you
instruct cleaning personnel on how to clean the set. As the set does not have any mechanical moving parts,
regular servicing and maintenance is not required. MOBOTIX recommends, however, that you occasionally
check that the device is functioning both reliably and properly.
Electromagnetic Compatibility (EMC)
Electromagnetic compatibility encompasses all unintentional or intentional malfunctions of electrical or electronic
equipment generated by electrical, magnetic or electromagnetic fields and processes, for example. This includes
interference from currents and voltages. The proof and verification of immunity to interference and a sufficiently
low level of electromagnetic interference are regulated by EMC directives and EMC standards.
The European EMC Directive defines electromagnetic compatibility as "the ability of a device, equipment or a
system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic
disturbances to anything in that environment."
The MOBOTIX MX-NPA-PoE Set complies with all relevant EMC and safety regulations (see Declaration of
Conformity).
