A DC PM has output power of 3000 W. PMs are configured based on the N+N backup
mechanism. To be specific, N (N>=1) PMs are configured for each of area A and area B
on the user side. The value of N x 3000 W must be greater than the power consumption
of the entire system. Table 1-77 shows the details.
If PMs are not fully configured, power cables are routed only for the PEM interfaces whose
corresponding PMs are installed. To facilitate the deployment of new power cables during capacity
expansion of PMs, you are advised to configure the PMs from the top down and leave a filler panel in
the position where no PM is not installed.

Table 1-78 describes recommended power supply configurations. You can choose the PM
configuration based on the actual platform.

1.8.6.2 System Power Supply Architecture
NE40E-X16A uses the non-partitioned power supply architecture. NE40E-X16A backplane
has one area, which houses two power inputs converged on backplane.
