The RBS has a modular architecture with scalable capacity. Various
configurations consist of one of more cabinets, each containing a number
of subracks. For detailed information on different RBS configurations, see
CONFIGURATION DATA
The RBS is powered by DC –48V.
2.4 Design for Environment
Ericsson has received a worldwide ISO 14001 certification granted by British
Standards Institute, BSI, for its Environmental Management System (EMS).
An important part of Ericssons Environmental work is Design for Environment
(DfE). The DfE guidelines are implemented in all new design projects. The
environmental work done for RBS 3202 has among other things resulted
in a complete materials declaration and an

document.
3 Hardware Structure
An RBS consists of one or more cabinets dependant on the configuration. A
single cabinet is currently configured to handle one Radio Frequency carrier
in three sectors.
Each cabinet contains four subracks that can be equipped with several plug in
units (PIU) depending on configuration and various traffic and transmission
capacities. Each subrack is equipped with its own fan. Each subrack is
equipped with its own fan. The location of the subracks, climate unit, and
interface connection field in a cabinet is shown in figure 2.
Figure 2 Hardware Locations
The numbers in the figure above denote:
• A) Interface Connection Field (ICF)
• B) Capacitor Unit (CU)
• C) Baseband (BB) subrack
• D) Radio Frequency (RF) subrack
• E) MCPA subrack
Each subrack houses a number of boards designed for different functions. The
boards and units are described later in this chapter
