LED
Description and actions
1 2 3 Fans 1-3 error LED LED on: an error has occurred to the fan the LED represents.
4 5 12 13 DIMMs 1-4 error LED (amber) LED on: an error has occurred to the DIMM the LED represents.
6 FPGA power status LED (green) 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.
7 FPGA heartbeat LED (green) 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).
