Installing the Modular Base
Station Equipment
The following sections describe the slot assignments 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.

BS-SH-VL Slot Assignments

The Base Station chassis comprises ten slots, as shown in Figure 3-7.
Figure 3-7: BS-SH-VL Chassis Slot Assignments
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 eight BS-AU-VL modules. Unused
slots should remain covered until required.
The design of the BS-SH-VL supports collocation of BreezeACCESS VL
Access Units with Access Units belonging to other BreezeACCESS families
using GFSK modulation, including BreezeACCESS II and BreezeACCESS
V. It supports any mix of BS-AU-VL modules with BreezeACCESS GFSK
BS-AU modules, including an optional BS-GU GPS module. If Access Units
belonging to other BreezeACCESS families are used, than it is necessary to
use two power supply module: one BS-PS-VL (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.
WARNING:
If two power supply modules are used in the same chassis, both power supply modules
must be of the same type. Do not use a mix of AC and DC power supply modules in the
same chassis.
