The very distributed nature of structured cabling systems leads to potentially catastraphic problems with induced surges from other equipment or external effects such as nearby lightning. Overvoltages can be transmitted from the source to anywhere else within the building, so damage or service interruption can break out almost at random. Cat.5 NP surge protectors will automatically protect these networks repeatably and reliably. Operation is completely automatic, the NP instantaneously limits overvoltages and diverts excess currents into the protected ground connection, eliminating the possibility of impulse energy being transferred to other parts of the network. After surge diversion, the NP automatically resets and is available for service once more.
Installation is simple and straightforward.
Patch cords are taken from the hub through the surge protector and then re-connected out to the appropriate user channel. The NP-RJ45 provides protection for individual pieces of equipment and can simply be inserted into the horizontal cable run using the RJ45 sockets on its front panel. Additional protection devices should be provided for other parts of the network or other systems which may be interconnected eg. Also, surge protection can only operate locally, so an NP protector installed at a central server cannot protect other network devices or individual computers. Services between buildings are particularly prone to high energy impulses and these lines should be protected using devices of the highest capability.
