When ordering IE4000, always order power supplies regardless of the power input at the site (AC or
DC).

For a PoE+ requirement, an AC input power supply is required.

If the PoE budget is insufficient with power input A, a second power supply can boost the PoE budget by connecting to power input B.

It is important to understand from the customer if PoE is needed and if the site power source is AC or
DC.
