2.4 Power the Base Stations
If the IPBSs are using PoE, the classifications must be considered. The PoE power source
(for example the ethernet switch) will allocate power according to the PoE classification
and not according to the real power usage.
The IPBL power supply will allocate power to both the IPBL and the connected RFPs.
As an alternative, the base stations can use a local AC-adapter for individual power supply.
