Huawei 30297461 BTS3012 embedded power and signal cabinet, GM51 subrack family Telecom System Card / Module

The GM51DCMB (material code 30297461) is a backplane board for the Huawei BTS3012 base station’s embedded power and signal cabinet, part of the same GM51 subrack family as the confirmed GM51DCCU cable connection unit and GM51DCSU signal connection unit. As a backplane, its role is to physically interconnect the other GM51-family cards in the common subrack, carrying power and signal buses between the cable/signal connection units and the rest of the cabinet’s electronics rather than performing active processing itself. The exact sub-position of this specific backplane variant within the BTS3012 cabinet is not independently documented beyond its designation as a backplane in the GM51 family, so its physical fit should be confirmed against your subrack’s build sheet before ordering. Operators maintaining legacy BTS3012 GSM sites keep backplane boards like this as spares, since a backplane fault can take an entire subrack out of service. Tech-Star (UK-based, shipped worldwide) supplies this as a tested spare. Get in touch with our team to confirm compatibility before ordering.
