and if there are alternatives, like , if PTP300/500 PIDU is operational for PTP250 and PTP300/500 LPU is operational for PTP250 and PTP650 PIDU is operational for PTP250 ??
The ODU should only be deployed with either a Cambium supplied PoE power supply or the PTP 300/500/600 Series PIDU. Do not use other power supply units, as they may damage the PTP 250.
I would also expect PTP300/500/600 LPUs to be compatible since the power supply is the same.
