1.8.3.2 System Power Supply Architecture
ME60-X8A uses the non-partitioned power supply architecture. ME60-X8A backplane has
one area, which houses two power inputs converged on backplane.
-48 V DC Power Supply
As shown in Figure 1-34, the ME60-X8A has two PEMs. Each PEM has eight inputs. There
are altogether 16 inputs (8 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 8 PMs can be configured based on the N+1 backup
mechanism.
