Figure 3-3 Outdoor scenario with AC power supply (BBU installed in an APM30H) (3)
In the 110 V or 220 V AC scenario, a BBU can be installed in an APM30H, which provides
power to a maximum of six RRUs. If more than six RRUs are configured, two APM30H cabinets
are required. Two APM30H cabinets can house two BBUs, which enable the base station to
work in triple mode. Figure 3-4 shows the typical scenarios when no backup power is required
and transmission space is required.
