Huawei 30293991 GM52-series embedded power and signal cabinet Telecom System Card / Module

The GM52DTRB (material code 30293991) is a backplane board for a Huawei GM52-series embedded power and signal cabinet, a sibling family to the GM51 cabinet range documented elsewhere in Huawei’s BTS3012-generation equipment. As a backplane, its role is to physically interconnect the cabinet’s active cards, carrying power and signal buses between them rather than performing active processing itself. The GM52 designation indicates a distinct (though related) cabinet/subrack variant from GM51, so this backplane is not necessarily interchangeable with the GM51DCMB/GM51DCTB backplanes documented separately; the exact host cabinet model should be confirmed against your site’s build sheet before ordering. Operators maintaining legacy Huawei embedded power cabinets 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.
