AC power supply
In the case of an AC power supply system, an AC power frame is placed outside the chassis
and installed with rectifier modules based on system power. The AC power frame is then
connected to the input terminals on the DC-PEMs to supply power for the system. (In short,
an external AC power frame is added to the DC power supply system to constitute an AC
power supply system.) Figure 1-35 shows the AC power supply system of the NE40E-X8.

Installing the AC power module in the same cabinet as the chassis is recommended. If the AC
power module cannot be installed in the same cabinet as the chassis, place it near the cabinet
and ensure correct cabling. Each power module provides four circuit breakers and four AC
power inputs.
