Huawei GM51DCCU BTS3012 embedded power and signal cabinet Telecom System Card / Module

The GM51DCCU is a Cable Connection Unit for the Huawei BTS3012 base station’s embedded power and signal cabinet, confirmed via Huawei BTS3012 hardware documentation. Fitted in slot 6 of the common subrack, it is a mandatory board that converts the subrack’s input/output signals, feeds in the incoming power supply, and provides EMI filtering to protect the rest of the cabinet’s electronics from conducted interference. It works alongside the related GM51DCSU signal connection unit and GM51 cabinet backplane boards to interconnect the BTS3012’s common subrack with the wider cabinet power and signalling system. As a foundational connection board rather than a processing card, the GM51DCCU is required for the subrack to function at all, making it a common spare for operators maintaining legacy BTS3012 GSM sites as the platform ages out of active production. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare. Get in touch with our team to confirm compatibility with your cabinet configuration before ordering.
