5. Typical Installation
In the simplest configuration (Figure 1), the data path from the network equipment (Ethernet interface), is
routed via a Power over Ethernet (PoE) injector (labelled ‘PSU’ in the figure) then via a copper cable to the
ODU (PSU port). Surge protection units should also be deployed as shown. A typical mast or tower
installation and wall installations is shown below (
Figure 2, 3 & 4 ) . Consult the user guide for detail of more
configurations.
Always site the radio equipment in a lightning protection zone:-
The equipment must be lower than the top of the tower or building or its lightning air terminal
The tower or building must be correctly grounded
