ESP Net 100/PoE - Power over Ethernet networks on Cat 5 cabling

\| esp product range \| questions & answers \|

Installation

Plug-in series connection Connect in series with the network cable, either:

a) near to where it enters or leaves the building, or
b) as it enters the network hub, or
c) close to the equipment being protected.

This should be close to the system's earth star point (to enable a good connection to earth).
