In the case of power supply failure, follow the instructions given below to replace the faulty unit.
If the current limit is operating continuously, then the system may either have a fault elsewhere
causing a power overload, or there may be a need for adding another power supply (If for example
you have added extra boards, drives, processors or memory).

You might feel initial resistance in sliding the power supply from its bay. Do not tilt or twist the supply;
this can damage components. Resistance is caused by the supply disengaging from its 40-pin connector.
Use even, steady pressure to remove the supply.
