An apparatus provisions power from a power budget to remote devices
configured to obtain phantom power. The apparatus includes, among other
things, a controller which is configured to identify a power demand for a
remote device (e.g., a power demand based on an actual cable loss), and
generate a comparison between the power demand for the remote device and
the power budget of the apparatus. The controller is further configured
to allocate power from the power budget provided by the power supply to
the remote device when the comparison indicates that the power budget
supports the power demand for the remote device, and reject allocation of
power from the power budget to the remote device when the comparison
indicates that the power budget does not support the power demand for the
remote device.
