3 Installation Scenarios
A DBS3900 mainly includes a BBU and RRUs. RRUs can be installed remotely so that a
DBS3900 can be deployed indoors or outdoors. When a DBS3900 is deployed outdoors with
AC or DC power supply, the BBU can be installed in an APM30H, TMC11H, or OMB. When
a DBS3900 is deployed indoors with DC power supply, the BBU can be installed in an IMB03,
19-inch rack of customers, or wall.
Table 3-1 describes the DBS3900 installation scenarios.
