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 135 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. See “Upgrading an RPI-8 to an RPI-16” on page 111.

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:
