The BSPS is delivered pre-installed in an Airspan cabinet. The only installation that is required includes the following: ! Installing the BSPS battery ! Connecting the BSPS temperature sensor to measure battery temperature ! Connecting the BSPS to the BSDU 7.1.1. BSPS Components The BSPS consists of the following basic components: ! DC Rectifier modules: The Rectifier converts the AC current to DC. The BSPS can house up to four rectifiers. The rectifiers are “hot plugged” and operate in parallel. This enables the user to define an “N+1”or “N+2”redundant system. Each rectifier has its own current sharing system, satisfying a complete sharing among rectifiers. ! System controller: provides BSPS management control and BSPS operating information ! Electronic Low Voltage Detector (ELVD): disconnects the battery from the load, avoiding damage to the battery when over-discharged. ! Battery: provides the BSPS system with back-up power ! Load and battery circuit breakers for DC protection and distribution ! DC Distribution unit: provides circuit breakers for distributing the output current to multiple BSDUs. The unit also contains a bypass switch to bypass the LVD. Note: For power redundancy, at least two rectifiers must be installed.

Connecting BSPS Power to BSDUs The BSPS’s DC Distribution unit provides circuit breakers for distributing power output to BSDUs housed in the WipLL cabinet. The DC Distribution unit contains a switch that provides an LVD circuit bypass option. When this switch is activated the battery is no longer protected against deep discharge and the system controller alarm is then activated. The distribution rack is provided with front panel and rear panel terminations for connecting to the BSPS main power rack. To connect the BSPS DC power supply to the BSDU: 1. Attach the shielded power cable connector (supplied) end that contains the wire for preventing power radiation, to the BSDU’s power port—labeled POWER -48 VDC. Ensure that the black-colored (i.e., negative) half of the connector is positioned at the top and the red-colored (i.e., positive) half at the bottom.
