About This Chapter
This describes the solutions for the auxiliary devices of the DBS3900. The DBS3900 uses a
modular structure. The basic modules of the DBS3900 are the BBU3900 and RRU3606. The
auxiliary devices of the DBS3900 include the indoor centralized installation rack, L-shaped
support, APM, storage battery cabinet, DCDU, EMUA, SLPU, ODF, DDF, DC power system,
and AC power system. The basic modules and auxiliary devices can be flexibly configured to
form integrated site solutions.
2.1 Indoor Centralized Installation of the DBS3900
This describes the indoor centralized installation of the DBS3900. In this mode, the major
modules are the BBU3900 and RRU3606. The BBU3900 supports -48 V DC input. The DC
RRU3606 supports -48 V DC input. The AC RRU3606 supports 220/110 V AC input.
Installing the DBS3900 on the indoor centralized installation rack or L-shaped support as a
macro base station makes it convenient for the operator to manage the spare components and
versions in a centralized manner and to perform maintenance and upgrade in future.
2.2 Indoor Distributed Installation of the DBS3900
