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.
