Note: Some adapters and hard disk drives draw more current than the rated maximums. These adapters and drives can be installed in the system; however, the power supply will shut down if the total power used exceeds the maximum power that is available.
Output protection
The power supply protects against output overcurrent, overvoltage, and short circuits. See the power supply specifications on the previous pages for details.
A short circuit that is placed on any dc output (between outputs or between an output and a dc return) latches all dc outputs into a shutdown state, with no damage to the power supply. If this shutdown state occurs, the power supply returns to normal operation only after the fault has been removed and the power switch has been turned off for at least one second.
If an overvoltage fault occurs (in the power supply), the power supply latches all dc outputs into a shutdown state before any output exceeds 130% of the power supply value.
