RPI unit 
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 (PSUs). 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 
installing a second PSU to the RPI-8 BIX UL. Refer to 
Upgrading an RPI-8 to an RPI-16 on page 119.
If RPIs are distributed throughout the site, the number and type 
of RPIs depend on the placement and powering plan of the 
base stations.
To determine how many base stations and how many PSUs 
you need for the number of base stations, use the following 
table:
