  40 Power over Ethernet, or PoE, is an increasingly popular
  way to deliver both power and data over existing Ethernet
  cable, thus freeing applications from the constraint of
  AC-power proximity. As the number PoE solutions has
  grown so has the applications’ appetite for power.
  A new proprietary standard, LTPoE++в„ў, satisfies this hunger
  by extending the PoE and PoE+ specifications to 90W of PD
  delivered power. LTPoE++ also dramatically reduces engineering
  complexity in power sourcing equipment (PSEs) and powered
  devices (PDs) when compared to other power-expansion solutions.
  Plug-and-play simplicity and safe, robust …
