3.2 Power Supply System
This chapter describes the power supply system of the ME60-X8.
3.2.1 Architecture of the Power Supply System
This section describes the features of the power supply system.
The ME60-X8 supports either DC or AC power supply.
In the case of a DC power supply system, four 70 A Power Entry Modules (PEMs) are inserted
at the rear of the chassis, working in 2+2 backup mode.
In the case of an AC power supply system, an AC power frame is placed outside the chassis and
installed with rectifier modules based on system power. The AC power frame is then connected
to the input terminals on the DC-PEMs to supply power for the system. (In short, an external
AC power frame is added to the DC power supply system to constitute an AC power supply
system.)
3.2.2 Distributed Architecture of the System
This section describes partitioned power supply on the ME60-X8.
As shown in
two power inputs. These four power inputs work in backup mode.
