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.
