Power supply FAILURE
Power supply in current limit
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).
Replacing a power supply
1.
Observe the precautions as given in Safety & Regulatory Notices at the front of this
handbook.
2.
Turn off and disconnect all peripheral devices connected to the system.
3.
Turn off the system by using the power on/off switch on the front panel AND unplug all AC
power cords.
4.
Remove the four screws holding the power supply to the back of the chassis.
5.
Using the flared, vertical edges as handles, slide the supply straight back from its bay.

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.
