System-board LEDs

This section contains information on the light-emitting diodes (LEDs) on the system board.


System-board LEDs
1 System power LED (yellow)2 XCC heartbeat LED (green)
3 FPGA heartbeat LED (green) 
  • 1 System power LED (yellow)
    • Off: No power supply is properly installed, or the LED itself has failed.
    • Blinking rapidly (four times per second): The node is turned off and is not ready to be turned on. The power button is disabled. This will last approximately 5 to 10 seconds.
    • Blinking slowly (once per second): The node is turned off and is ready to be turned on. You can press the power button to turn on the node.
    • On: The node is turned on.
  • 2 XCC heartbeat LED (green)
    • Blinking slowly: XCC is functioning.
    • Blinking rapidly and constantly: XCC is initializing or malfunctioning.
    • On: XCC is malfunctioning.
    • Off: XCC is malfunctioning.
  • 3 FPGA heartbeat LED (green)
    • On or off: FPGA is not working.
    • Blinking slowly (once per second): The node is turned off and is not ready to be turned on. The power button is disabled. This will last approximately 5 to 10 seconds.
