3.2 Power Supply System
This chapter describes the power supply system used by the CX600.
3.2.1 Architecture of the Power Supply System
This section describes the features of the power supply system.
The CX600-X16 supports either DC or AC power supply.
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.)
3.2.2 Distributed Architecture of the System
This section describes partitioned power supply on the CX600-X16.
As shown in
having two power inputs. These eight power inputs work in backup mode.
