RBS 2206
5 Hardware Units
A high level of availability is achieved using strict functional modularity with a
system of standardised units. A failed unit can easily be replaced by a new
one. It is possible to add up to three new units in the PSU/DXU magazine.
The RBS 2206 cabinet contains the radio equipment, power supply and the
climate equipment (fans). All required transmission equipment and battery
back-up must be housed outside the cabinet.
Outside equipment is listed under optional units. Not all HW units are covered
in this section, only those directly related to RBS.
5.1 Standard Hardware Units
This section briefly describes the standard hardware units required for
functionality, irrespective of configuration or frequency.
