This circuit is drawn out in such a way that it can be easily assembled on vero-board. Not all 7 relays are required eg JF only uses only two, northfeild five and Carrick Hill will only use one.
The aim of this circuit is to enable a system script to reset or power cycle an ethernet AP's when they crash, which does happen from time to time. This is very usefull where access to a site is limited.
