Huawei fan units, mounting kits and filter units

Huawei fan and bracket part numbers are numeric material codes without a readable naming convention, so match by cabinet or module model rather than trying to decode the number — a 2U fan module for a BBU3900 cabinet and one for a DBS3900 cabinet are different parts despite looking similar. RRU mounting kits are specified by RRU series and mount type (pole, wall, channel-steel), and a kit sized for one RRU generation does not always fit the next.

Give the exact cabinet or RRU model the part fits, not just 'Huawei fan' or 'Huawei bracket' — Huawei's material codes are cabinet-specific and we need the host equipment model to confirm the right part before quoting. Condition is stated per quotation — new, new-surplus or refurbished — and where a destination does not admit used network equipment (Algeria is the usual example) we quote new. Hardware only: software licensing remains between the buyer and the manufacturer. Destination type approval and import permits (CST/SABER, TDRA, ICASA, CA, CMC, ARPCE) are the buyer's responsibility and we will say so on the quotation.

These are maintenance spares for cabinet and RRU generations that remain widely deployed; supply is a mix of new stock where Huawei still manufactures the part and refurbished/pulled units for older cabinet generations that Huawei has discontinued.
