cnMatrix EX1O28-P SWITCH PoE LIGHT INDICATOR OUT OF DISPLAY

Hi, I am facing a minor issue with the indicator light on my device (cnMatrix1028-P switch); the PoE light indicator (RED) has suddenly powered off. The switch which is a PoE switch now appears as a non-PoE switch in terms of the display of light activities. What must have gone wrong with the switch and what can I do to bring it back to normal?
