Alcatel-Lucent Nokia 3HE10329AA 7750 SR Series Router Module

The Alcatel‑Lucent Nokia 3HE10329AA is a modular interface and forwarding unit for the 7750 SR service router family. Engineered to deliver flexible port configurations and high‑performance packet processing, this module supports a wide range of network interfaces, including Gigabit Ethernet, 10 Gigabit Ethernet, and legacy TDM options depending on the mezzanine adapter. It is a core component for scaling 7750 SR systems in carrier and data center environments.

Overview

The 3HE10329AA module is based on the programmable network processor architecture used across the 7750 SR line, enabling rapid feature introduction without hardware changes. It can be deployed as an I/O module in chassis slots, providing physical connectivity and offloading forwarding decisions from the control plane. The module is compatible with the 7750 SR‑7 and SR‑12 chassis and works seamlessly with SFM fabric modules for high‑throughput inter‑slot communication.

Key Features

• Modular design with support for different physical interface sub‑modules (MDA)

• High‑performance forwarding up to 120 Mpps

• Hardware acceleration for MPLS, VPLS, and IPsec

• Advanced traffic management with hierarchical QoS

• Supports IPv4, IPv6, and MPLS forwarding in hardware

• Integrated in‑service software upgrade (ISSU) capability

• Hot‑swappable for maintenance and upgrades

Technical Specifications

• Form Factor: 7750 SR slot‑compatible

• Forwarding Rate: Up to 120 Mpps

• Memory: 1 GB on‑board SRAM for tables

• Interface Options: 8x10GE, 24xGE, or mixed TDM/Ethernet via MDA

• Power Consumption: 150 W to 250 W depending on configuration

• Operating Temperature: 0°C to 45°C

Applications

This module is suitable for core routing, edge aggregation, and data center leaf‑spine architectures. It enables service providers to offer high‑bandwidth VPN services, broadband aggregation, and cloud connectivity with deterministic performance. Its flexible interface options allow adaptation to both legacy and next‑generation network infrastructures.

Compatibility and Integration

The 3HE10329AA is compatible with the 7750 SR‑7 and SR‑12 chassis and requires SR OS release 12.0 or later. It interoperates with other 7750 SR line cards, SFM modules, and control processors. The module supports industry‑standard management protocols and can be monitored via the 5620 SAM or third‑party NMS.

Installation and Maintenance

Installation follows standard procedures: power down the slot, insert the module, and tighten the ejector mechanisms. The system automatically discovers the module and loads the appropriate firmware. Maintenance includes periodic cleaning of optical ports (if equipped) and software upgrades performed through the management interface.

Conclusion

The Alcatel‑Lucent Nokia 3HE10329AA 7750 SR Series Router Module provides a flexible, high‑performance building block for modern IP/MPLS networks. Its modular interface architecture, robust forwarding capabilities, and seamless integration make it a reliable choice for scaling service provider and enterprise routing infrastructures.
