2.5 Power
¾ The SDA-4S is a switch providing the MicroMAX BSR with -48 VDC power supply, and
10/100BaseT interface with the subscriber's PCs/network.
¾ The BSDU is also responsible for providing BSRs with -48 VDC power supply and for
synchronizing BSDUs, BSRs and Base Stations (when a GPS is implemented).
¾ An external AC/DC power converter (optional) is available in the event -48 VDC is not
available at BS site. Contact your Airspan supplier.
