Power requirements of the components
Maximum power consumption of the auxiliary components
Maximum permitted power con-
sumption
USB device High current 1 A - - 10 W (for all USB devices)
8 W (for the whole device)
1
The total power of the PCIe and USB cards may not exceed 15 W
Note
Device can overheat!
To avoid overheating, the power loss per PCIe slot should not exceed 8
watts.
Integrated DC power supply
Output power of the power supply
Hold-up time ≥20 ms with 20.4 V (DC_FAIL is active after > 5 ms)
Note
Inrush current
At least 5 A inrush current for 15
ms is required for device startup.
The peak value of the starting current depends on
the input voltage and the impedance of
V DC power supply. Peak currents greater than 6.5 A are possible. This will not have
a negative impact on device functionality.
