2.6 Installing the Modular Base Station
Equipment
The following sections describe the slot assignment for the Base Station chassis,
provide illustrated descriptions of the power supply modules and Access Unit
network interface modules, and describe how to install the Base Station
equipment.
2.6.1 BS-SH Slot Assignment
The Base Station chassis comprises ten slots, as shown in Figure 2-19.
Figure 2-19: BS-SH Chassis Slot Assignment
To enable power supply redundancy, two BS-PS power supply modules can be
installed in the wider side slots. If a single power supply module is used, it can be
inserted into either one of the two available slots.
The remaining eight slots can hold up to six BS-AU modules. Unused slots
should remain covered until required.
The design of the BS-SH supports collocation of BreezeACCESS VL Access Units
with Access Units belonging to other BreezeACCESS families using GFSK
modulation. It supports any mixture of BS-AU modules with BreezeACCESS
GFSK BS-AU modules, including an optional BS-GU-GPS module. If Access Units
belonging to other BreezeACCESS families are used, then it is necessary to use
two power supply modules: one BS-PS (AC or DC) power supply for the
BreezeACCESS VL Access Units and one BS-PS GFSK (AC or DC) for the
BreezeACCESS GFSK Access Units.
