Microprocessor-board status LEDs (other than light path diagnostics)LED DescriptionBMC heartbeat When this LED is flashing, it indicates normal operation of thebaseboard management controller.FPGA heartbeat When this LED is flashing, it indicates normal operation of the FPGA(field-programmable gate array) chip.Machine check When this LED is lit continuously, the server is prepared to capture amachine check. When this LED is flashing, the server has captureda machine check. When this LED is off, the server is not prepared tocapture a machine check.Chapter 2. Installing optional devices 23
