Huawei CC03PWX Power Supply

The Huawei CC03PWX (PWX) is a secondary power board used within Huawei’s C&C08 digital program-controlled telephone exchange system, a large-scale PSTN switching platform historically deployed by telecom operators for voice call switching. Within the C&C08 equipment cabinet, the PWX board forms part of the secondary power distribution and control chain, working alongside the primary power system to regulate and route DC power to the exchange’s control and service shelves. The C&C08 platform was one of Huawei’s earliest large-scale carrier switching products and remains in service in some legacy telecom networks still supporting circuit-switched voice infrastructure. As with other slot-in boards in the C&C08 architecture, the CC03PWX is a field-replaceable unit intended to be swapped during maintenance without disturbing the wider exchange. Tech-Star (UK-based, shipped worldwide) supplies tested Huawei legacy exchange hardware for engineers maintaining C&C08 deployments. Get in touch to confirm compatibility with your system.
