Siemens S30777-Q0750-X000-04 backplane for HiPath 3550 PBX system.

The Siemens S30777-Q0750-X000-04 is a backplane assembly designed for the HiPath 3550 private branch exchange system. This component serves as the central interconnection board, providing the physical and electrical connections between the various expansion cards, processor modules and peripheral interfaces within the HiPath 3550 chassis.

The backplane is an essential infrastructure component of the HiPath 3550, a mid-range PBX platform that was part of the Siemens HiPath 3000 series. This system family was designed for small to medium-sized enterprises requiring unified communications, supporting both digital and IP telephony deployments.

The HiPath 3550 and its associated components are legacy products following Siemens’ exit from the enterprise communications market and the subsequent transition of the portfolio through Siemens Enterprise Communications to Unify. This backplane remains relevant for organisations maintaining existing HiPath 3550 installations and requiring replacement parts to sustain their telephony infrastructure.
