Hardware Units
6.1 Standard Hardware Units
This section briefly describes the standard hardware units required for function,
irrespective of configuration or frequency.
ACCU
The AC Connection Unit (ACCU) connects, disconnects, and distributes the
incoming AC power supply to the PSUs and the climate unit. It consists of
two parts: an ACCU Connection Unit (ACCU-CU) and an ACCU Distribution
Unit (ACCU-DU). ACCU-02 is used in RBS 2106 and ACCU-05 is used in
RBS 2106i and RBS 2106 V3.
Number of units: 1
BFU
The Battery Fuse Unit (BFU) supervises connection or disconnection of the
batteries. It can also be used to provide prioritized power supply, for example,
to the transmission equipment.
Two types of BFU are available: BFU 21 and BFU 32. BFU-21 is used in RBS
2106 and RBS 2106i. BFU-32 is used in RBS 2106 V3.
Number of units: 1
Climate Unit
The climate unit maintains the internal temperature and humidity inside the
cabinet. The climate unit is mounted in the door of the cabinet.
Two types of climate units are available:
• Combined climate unit that provides cooling by use of heat exchanger
and refrigeration units
• Heat exchanger climate unit that provides cooling by use of a higher
efficiency heat exchanger unit.
Both types of climate units include heating elements and the heat
exchanger function is DC powered.
Number of units: 1
CDU
The Combining and Distribution Unit (CDU) is the interface between
the transceivers and the antenna system. All signals are filtered before
transmission and after reception by means of bandpass filters. The CDU allows
several dTRUs to share antennas.
