Status LED, one bicolor:

  • Off—PIC not enabled
  • Green—PIC is operating normally
  • Red—PIC has an error or failure

Port LEDs, one pair:

  • Link—If green, the port is online; if there is no light, the port is down
  • RX—If flashing green, the port is receiving data; if there is no light, the port might be on but is not receiving data
