Description	On: No liquid leakage or cable break alert. Slow blinking (about two flashes per second): Cable break alert. Fast blinking (about five flashes per second): Liquid leak alert.
Action	If the cable breaks, replace the NeptAir module or NeptCore module (trained technicians only). If liquid leakage happens: For NeptAir module problem determination and troubleshooting, see Liquid cooling module problems (NeptAir module). For NeptCore module problem determination and troubleshooting, see Liquid cooling module problems (NeptCore module).
