Power Module Mappings
The ME60-X16A supports multiple power supply scenarios, which vary in the installed PEMs
and PMs. Table 1-62 lists the mappings between power supply scenarios and PEMs/PMs.
Table 1-62 Mappings between power supply scenarios and PEMs/PMs on the ME60-X16A
Power Supply Scenario PEM PM
-48 V DC power supply DC PEM DC PM
AC power supply AC PEM  2700 W AC PM
 3000 W AC&HVDC PM
240 V HVDC power supply HVDC PEM 3000 W AC&HVDC PM
380 V HVDC power supply HVDC PEM 3000 W AC&HVDC PM
-48 V DC power supply system supports N+1 (1 indicates the number of backup modules)
PMs power module backup. The AC, 240 V HVDC, and 380 V HVDC power supply systems
supports N+N (N indicates the number of working modules)PMs power module backup. The
power supply system supports the backup of power supply areas A and B on the user side,
ensuring that the entire system can work properly if any power supply area fails.

N+1(-48 V DC)
The ME60-X16A has four PEMs. Each PEM has eight inputs. There are altogether 32
inputs (16 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 16 PMs can be configured based on the N+1
backup mechanism. Figure 1-51 and Table 1-63 show the mappings between PEMs and
PMs.
