Symptom

Corrective Steps

The PD does not operate
  1. Ensure that the terminal block is assembled properly.
  2. Ensure that the power source voltage is between 20-60V DC and can carry out PWR of 80W.
  3. Verify that you are using a standard Category 5/5e/6, four-pair, straight-wired cable.
  4. Verify that PD is connected to the DATA & POWER OUT port.
  5. If an external power splitter is in use, replace it with a splitter in good condition.

The end device operates, but there is no data link

  1. If an external power splitter is in use, replace it with a splitter in good condition.
  2. Verify that for this link, you are using standard UTP/FTP Category 5 straight (noncrossover) cabling, with all four pairs.
  3. Verify that the Ethernet cable length is less than 100 meters from Ethernet source to the IP terminal.
  4. Ensure input Ethernet cable is connected to the DATA IN port.

LED Behavior

  1. Power 1: If this LED emits (green), then there is a working power source connected to the power 1 control circuit.
  2. Power 2: If this LED emits (green), then there is a working power source connected to the power 2 control circuit.
  3. Alarm: If this LED emits (red), then there is a problem with one of the power sources.
  4. PoE:
    1. If this LED emits (green), then there is power delivered to the PD device through 4-Pair.
    2. If this LED emits (yellow), then there is power delivered to the PD device through 2-Pair.
    3. If this LED blinks (green), then there is a failure with the PD device.
