Note the derating requirements of protection components when using protection components
such as fuses and circuit breakers. If the current of a PDF is less than 63 A, it cannot supply
power to the NE40E-X16A. In this case, reconstruct power supply in the equipment room.
If the front-end PDF does not provide enough power inputs, configure a PDB that meets
the following requirements:
− The current of each channel output by the DC PDB is not less than 63 A.
− Double-channel backup is used.
− The input current is not less than the sum of current of its connected output lines.
1.8.6.5 2700 W AC PM
The PM accesses external AC power through PEMs, the PMs convert AC power into
regulated DC power and output the power to the power supply backplane.
