The ME60-X8A supports N+N backup for PMs. The power supply system supports the
backup of power supply areas A and B on the user side. Every N power modules are
connected to one power supply area, ensuring that the entire system can work properly if
any power supply area fails.
The ME60-X8A has two PEMs. Each PEM has four inputs. There are altogether 8 inputs
(4 inputs in each of area A and area B). Each PM has two inputs. The two inputs are from
power supply areas A and B, respectively. In this manner, power supply areas A and B
back up each other. A maximum of 8 PMs can achieve a maximum of 4+4 backup.
Figure 1-33 and Table 1-32 show the mappings between PEMs and PMs.

Power Supply Principles
PEMs are integrated into the chassis and do not need to be configured onsite. Do not remove
and install PEMs onsite. PMs can be configured based on the overall power consumption of
the device to flexibly supply power.
