If the PSU does not function as expected, follow these steps:
1.Check all cable connections are correct and secure.
2.For DC models, check that the standby switch has been pressed and is in the ON position.
For AC models, check the PSU is receiving the correct AC voltage.
3.If the LEDs indicate a PSU fault, replace the PSU or have it serviced by authorised service personnel.
