Figure 2-10 Pem Connectivity - Emerson AXP640-DC2 Installation & Use Manual

Each PEM powers two separate power domains A and B and each domain supports 60A power
rails to supply power to the AdvancedTCA slots.
The PEMs are hot-swappable and will not cause a fault when one is removed for replacement.
Two PEMs are required to support 2N redundancy. If your system is configured for redundant
operation using two power feeds, they operate in load sharing where the total load is equal to
or less than what one power feed can provide.
