5.2 Error Codes
5.2.1 Blinking Error Codes
Error occurs
The power supply uses the LEDs on the SM300 front plate to signal errors which
are occurring during a time were no USB communication is possible (e.g. booting
time).
Error code LED

5.2.1.1 Module Overtemperature Error (OVR_TMP_ERROR)
Overtemperature
of modules
The overtemperature blinking code is executed when there is an overtemperature
in the system from the modules while the system is making the power on self test.
Blinking code
The green led and the red led will blink inverted.
5.2.1.2 Power Supply Overtemperature Error (BOARDMON_TMP_ERROR)
Overtemperature
of power supply
The overtemperature blinking code is executed when there is an overtemperature
in the power supply measured by the monitor IC while the system is making the
power on self test.
Blinking code
The green led and the red led will blink together.
5.2.1.3 Digital Voltage Error (BAD_DIGI_VOLTAGES)
Overvoltage or
undervoltage of
digital voltage
The digital voltage blinking code is executed when there is detected over or under
voltage in the digital voltages in the power supply measured by the monitor IC
while the system is making the power on self test.
Blinking code
The green led and the yellow led will blink inverted.
5.2.1.4 Analog Voltage Error (BAD_ANALOG_VOLTAGES)
Overvoltage or
undervoltage of
analog voltage
The analogue voltage blinking code occurs when over or under voltage has been
detected in the analogue voltages in the power supply. This is measured by the
monitor IC while the system generating power during the self test.
Blinking code
The green led and the yellow led will blink together.
5.2.1.5 Main DC Voltage Error (BAD_MAIN_DC_VOLTAGE)
Overvoltage or
undervoltage of
main DC voltage
The main DC voltage blinking code occurs when over or under voltage has been
detected in the DC voltages in the power supply. This is measured by the monitor
IC while the system is generating power during the self test.
Blinking code
The green led and the red led will blink together.
