receptacle is the correct type, supplies the required voltage, and is
properly grounded.

momentarily while the port is tested.
— The blue/green and amber LEDs associated with Fibre
Channel ports blink momentarily while the ports are tested.
4. After successful POST completion, the PWR LED remains
illuminated and all amber LEDs extinguish.
5. If a POST error occurs, go to MAP 0000: Start MAP to isolate the
problem.
