Description and actions
LED on: an error has occurred to the fan the LED represents.
LED on: an error has occurred to the DIMM the LED represents.
The FPGA power LED helps to identify different FPGA errors.
• LED blinking rapidly (four times per second): The FPGA
permission is delayed.
• LED blinking slowly (once per second): the FPGA is read to power
on.
• LED on: The FPGA power is on.
This LED indicates power-on and power-off sequencing.
• LED blinking: the system is functioning properly, and no action is
necessary.
• LED not blinking: replace the system board (trained technician only).
