Check module cooling air flow and fan
operation.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity.
See appropriate hardware manual.
Check inside of cabinet and heatsink of
supply module for dust pick-up. Clean
whenever necessary.
Supply module temperature is excessive
due to eg, module overload or fan failure.
