Intersting, the Ault news release about these states:

  "IEEE 802.3af-compliant PW130 units protect against power applied to a
  non-802.3af-compliant load. These units recognize proper power supply
  with intelligent signatures before enabling full output power. The PW130
  also protects against more than one power supply per cable, regardless
  of polarity. It provides current limiting, detects when the load is
  unplugged, resets its detection circuitry, protects against miswiring
  and automatically avoids power application to a non-compliant load
  device."
