In the case of a DC power supply system, eight 70 A Power Entry Modules (PEMs) are
inserted at the rear of the chassis, working in 4+4 backup mode.
In the case of an AC power supply system, two AC power frames are placed outside the
chassis and installed with rectifier modules based on system power. The AC power frames are
then connected to the input terminals on the DC-PEMs to supply power for the system. (In
short, external AC power frames are added to the DC power supply system to constitute an
AC power supply system.)
2.2.2 Distributed Architecture of the System
This section describes partitioned power supply on the NE40E-X16.
As shown in Figure 2-5, the NE40E-X16 backplane is divided into four areas, with each area
having two power inputs. These eight power inputs work in backup mode.
