Huawei Atn 910d-a Datasheet ((hot)) May 2026

1. Summarize the device’s purpose and key specs (based on publicly available Huawei product overviews).
2. Give you a structured outline you can use to write your own paper, including where to find authoritative data.
3. Explain how to interpret datasheet parameters for this type of access router.

2. Key Interface Specifications

Despite its size, the ATN 910D-A offers surprising port density. The typical configuration includes:

• Downlink Ports (User Side):
  • 4 x GE (Gigabit Ethernet) electrical ports (RJ45).
  • 4 x FE (Fast Ethernet) electrical ports.
• Uplink Ports (Network Side):
  • 2 x Combo ports (supports either RJ45 electrical or SFP optical modules).
  • Note: These combo ports support 100/1000BASE-X, allowing fiber runs up to 80km depending on the SFP module.
• Console Port: 1 x RJ45 for local management.

The Takeaway: With 10 user ports and 2 uplinks, you can aggregate multiple cameras, sensors, or cell radios into a single 1GE fiber backhaul.

Interface & Port Density

The ATN 910D-A is modular but comes with fixed ports plus slots:

• Fixed ports: 4 x GE (Gigabit Ethernet) electrical RJ45
• Interface card slots: 2 x SIC slots (Smart Interface Cards)
• Common SIC options:
  • 2 x GE optical (SFP)
  • 4 x GE electrical
  • 1 x 10GE optical (SFP+)
• Console port: 1 x RJ45 (local management)
• Alarm port: 1 x alarm input/output

Max switching capacity: ~8 Gbit/s (non-blocking) Huawei Atn 910d-a Datasheet

What is the ATN 910D-A?

The Huawei ATN 910D-A is a hardened, fanless access router designed for the IP edge of mobile backhaul, enterprise access, and utility networks. It’s part of Huawei’s ATN (Access Transport Node) series, optimized for outdoor or unventilated indoor environments.

Unlike bulky chassis-based routers, the 910D-A fits in tight spaces while handling carrier-grade MPLS, synchronization, and QoS.

2.2 Interface and Port Mapping

The ATN 910D-A features a fixed hardware architecture with field-replaceable pluggable optics. Summarize the device’s purpose and key specs (based

| Port Type | Quantity | Description | | :--- | :--- | :--- | | 10GE/GE Optical (SFP+) | 4 ports | Two ports support 10GE; all support 1GE (SFP/SFP+). Used for uplinks to aggregation nodes or downlinks to base stations. | | GE Electrical (RJ45) | 8 ports | 10/100/1000BASE-T (Copper). Ideal for legacy base stations, surveillance, or management. | | Console port (RJ45) | 1 port | For CLI management. | | Management port (GE) | 1 port | Dedicated out-of-band management (10/100/1000). | | External Alarm port | 2 ports | For environmental monitoring (door sensors, fire alarms). |

Note: The device supports pluggable optical modules (SFP/SFP+) from Huawei’s certified list, including eSFP, SFP+, and BIDI optics for fiber conservation.

Comparison (brief)

• Compared with enterprise switches, the ATN 910D-A emphasizes environmental resilience and deterministic behavior over large feature-sets like deep L3 routing.
• For heavy L3 routing or datacenter use, choose a core router/switch; for field deployments, choose industrial switches like the ATN series.

Layer 2 Features

• VLAN (802.1Q): up to 4K active VLANs.
• QinQ (Stacked VLAN): double tags, up to 4096x4096.
• STP/RSTP/MSTP.
• LACP (802.3ad link aggregation) – up to 8 ports per group.
• ERPS (Ethernet Ring Protection Switching) – sub-50ms convergence.
• LLDP, 802.1x.

3. Interface Cards (SICs) – Expanding the ATN 910D-A

One of the strongest features detailed in the Huawei ATN 910D-A datasheet is its support for interchangeable Service Interface Cards. Each slot can host one of several SIC types. Downlink Ports (User Side):

| Card Model | Interface Type | Port Count | Use Case | |------------|----------------|-------------|-----------| | SIC-1T1E1 | T1/E1 (channelized) | 8 ports | Legacy TDM backhaul | | SIC-4GEF | GE (optical/electrical) | 4 ports | Ethernet aggregation | | SIC-2XGF | 10GE SFP+ | 2 ports | High-bandwidth uplinks | | SIC-8FE | Fast Ethernet (RJ45) | 8 ports | Low-speed sensor/device aggregation | | SIC-2GEC | GE combo (copper/SFP) | 2 ports | Flexible media conversion |

Maximum configuration example:
2x SIC-4GEF → 8 GE ports + 4 fixed GE combo ports + 2x 10GE uplinks = 14 GE + 2x 10GE logical interfaces.
