Huawei Atn 910d-a Datasheet May 2026

This is where the datasheet shines. The ATN 910D-A is built for harsh environments.

Pro Tip: The "A" in the model number indicates a specific hardware version that includes enhanced surge protection (typically 4kV common mode), making it ideal for tower-mounted gear.

The ATN 910D-A is engineered for non-blocking forwarding under real-world traffic patterns.

| Metric | Value | |--------|-------| | Switching Fabric Capacity | 48 Gbit/s | | Forwarding Rate (64-byte packets) | 24 Mpps (million packets per second) | | MAC Address Table Size | 32K entries | | IPv4 Route Table (FIB) | 64K routes (default) / up to 128K with license | | IPv6 Route Table | 32K routes | | Jumbo Frame Support | Up to 9216 bytes | Huawei Atn 910d-a Datasheet

The device supports both store-and-forward and cut-through switching modes, selectable per VLAN or port.

Note: The device supports 1+1 power redundancy with dual DC feeders. No AC/DC mixing is allowed.

Configuration:

Result: < 50ms protection switching, 10Gbps backhaul capacity for ~16 macro cells.

The ATN 910D-A includes a comprehensive security suite suitable for carrier-grade deployments.

No built-in firewall or IPS (design assumes external security appliances). This is where the datasheet shines

To help you decide, here’s how the “D-A” variant compares to the previous “C” model:

| Feature | ATN 910C (Older) | ATN 910D-A (Current) | | :--- | :--- | :--- | | 10GE ports | 2 | 4 | | GE copper | 8 | 8 (same) | | 1588v2 | Ordinary clock | Boundary + Ordinary clock | | SyncE | Yes | Enhanced (master/slave) | | MACsec | No | Yes | | Temperature range | -20°C to +55°C | -40°C to +65°C | | Packet buffer | 4 MB | 12 MB |

Verdict: Choose the 910D-A for 5G fronthaul, harsh outdoor cabinets, or any network requiring high-accuracy boundary clock and MACsec encryption. Pro Tip: The "A" in the model number
