Huawei Atn 910d-a Datasheet [repack] May 2026

Note: The ATN 910D-A does NOT require a separate fan unit – it is passively cooled within the 1U chassis, reducing noise and failure points. To help you decide, here’s how the “D-A” variant compares to the previous “C” model:

The device supports pluggable optical modules (SFP/SFP+) from Huawei’s certified list, including eSFP, SFP+, and BIDI optics for fiber conservation. 2.3 CPU & Memory Resources | Component | Detail | | :--- | :--- | | Processor | Quad-core ARM based NPU (Network Processor) | | DRAM | 4 GB (standard) | | Flash memory | 2 GB (expandable via USB) | | Packet buffer | 12 MB (for burst absorption) | 3. Performance Metrics (Switching & Routing) The ATN 910D-A is not just a switch; it’s a carrier-grade router. Below are the critical performance line items. Huawei Atn 910d-a Datasheet
