Installing the BSPS Hardware Installation Manual
7-2 Airspan Networks Ltd. 02030311-03
The BSPS provides the BSDUs/BSRs with the following:
! Power supply of –48 VDC to BSDUs/BSRs
! Power redundancy in case of power failure. The BSPS charges a battery bank
that provides this power redundancy during mains failure. Thus, the BSPS acts
as a DC-UPS with a battery connected to it. The size of the battery determines
the backup and charging time. Since the system is current limited, the maximum
battery size is based on that limit.)
! Remote management and monitoring through WipLL’s WipManage or
WipConfig management application.
The BSPS is delivered pre-installed in an Airspan cabinet. The only installation that
is required includes the following:
! BSPS battery
! BSPS temperature sensor to measure battery temperature
! Connecting the BSPS to the BSDU
