2.3.2 Power Requirements
The MVME8100 / MVME8110 uses the backplane +5V source to power each on board power
supply. The +3.3V backplane supply is not utilized in order to have backward compatibility with
old 3-row chassis. The -12V and +12V is routed through to the XMC and PMC connectors. The
power estimates provided in the following table is the total board consumption from +5V,
excluding the PMC/XMC, SATA HDD/SSD and USB devices.
The following table shows the power limits due to the available 5 volts pins, when the
MVME8100 is installed in either a 3-row or 5-row chassis and when PMCs/XMCs are present.

Voltages Minimum Normal Maximum
+5.0V 4.875V (-2.5%) 5.0V 5.25V (+5%)
