-48 V DC Power Supply
As shown in Figure 1-53, the ME60-X16A has four PEMs. Each PEM has eight inputs. There
are altogether 32 inputs (16 inputs on each of area A and area B). Each PM has two inputs.
The two inputs are from power supply areas A and B, respectively. The PM converts the
power and outputs the power to the power supply backplane. In this manner, power supply
areas A and B back up each other A maximum of 16 PMs can be configured based on the N+1
backup mechanism.

AC and HVDC Power Supply
As shown in Figure 1-54, after the external power is input to PMs through PEMs, the PMs
convert power and output the power to the power supply backplane. Each PEM provides four
channels of power inputs (with two partitioned into area A and two partitioned into area B) for
four PMs. There are 16 PMs on the device.
