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.
