Figure 9 : RPI components
There are two versions of the RPI unit: the RPI-8 BIX UL, which supports up
to eight Base Stations; and the RPI-16 BIX UL, which supports up to 16 Base
Stations. Each RPI has a connection board and either one (RPI-8 BIX UL) or
two (RPI-16 BIX UL) power supply units. The maximum input power
consumption of an RPI is 240 W. If a UPS 48 V dc backup source is used, the
maximum input power requirement of the RPI is 140 W.
You can upgrade an RPI-8 BIX UL to an RPI-16 BIX UL by attaching a
second power supply unit to the RPI-8 as described on page 31.
To determine the type and number of power supply units you need for a given
number of Base Stations, use Table 2 on page 22.
WARNING!
An RPI unit should not be installed where its
outputs are exposed, even when the Base
Station is installed with the TCM lines
exposed. An RPI unit should be installed in
the same building as the Base Stations the
RPI supports.
