2.3.2 Power Requirements
Up to 90 W (18 A at 5 V) of power can be supplied to the board in a 5-row backplane. 70 W
(14 A at 5 V) can be supplied in a 3-row backplane. The board requires 18 W to 22 W (3.6 A to
4.4 A at 5 V) to operate. The remainder is available to the PMC site, but you have to make sure
to not exceed 10 A (33 W) on 3.3 V.
The table below provides an estimate of the typical and maximum power required.
The following table shows the power available when the MVME4100ET is installed in either a 3-
row or 5-row chassis and when PMCs are present.
Product Damage
High humidity and condensation on the board surface causes short circuits.
Do not operate the board outside the specified environmental limits.
Make sure the board is completely dry and there is no moisture on any surface before
applying power.
