Power Supply Principles
PEMs are integrated into the chassis and do not need to be configured onsite. Do not remove
and install PEMs onsite. PMs can be configured based on the overall power consumption of
the device to flexibly supply power.

N+1(-48 V DC)
A DC PM has output power of 2200 W. Use the N+1 PM backup mechanism as an
example. N+1 PMs are configured for power supply, with N being the number of PMs
required for the power consumption of the entire device. The value of N x 2200 W must
be greater than the overall power consumption of the entire device. Table 1-41 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.

N+N(AC/HVDC)
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 1-42 shows the details.
