Alcatel-Lucent 76-0300-02 CSM-V2 PCB

The Alcatel‑Lucent 76‑0300‑02 CSM‑V2 is a printed circuit board that serves as a central control and switching module for telecom and networking chassis. This unit provides system management, switching fabric, and diagnostic functions, ensuring coordinated operation of line cards, power supplies, and cooling modules. It is a critical component for high‑availability platforms such as routers, switches, and optical transport nodes.

Overview

The CSM‑V2 (Control and Switching Module Version 2) is an enhanced version of the earlier CSM, offering higher processing power, larger memory, and faster fabric connectivity. It is typically installed in a dedicated slot of the chassis, where it manages initialization, system monitoring, and inter‑module communication. The board features a high‑speed backplane interface, on‑board diagnostics, and redundant operation support for active‑standby configurations.

Key Features

• Centralized system control and management

• Integrated switching fabric for data plane traffic

• Redundant operation with hitless failover

• Comprehensive diagnostics and self‑test capabilities

• Multiple management interfaces (Ethernet, console, alarm)

• Hot‑swappable for field maintenance

• Real‑time monitoring of voltages, temperatures, and fan speeds

Technical Specifications

• Processor: Multi‑core, ≥ 1 GHz

• Memory: 2 GB DRAM, 1 GB flash

• Switching Capacity: Up to 100 Gbps (fabric interface)

• Management Ports: 1x 10/100/1000Base‑T, 1x RS‑232 console

• Alarm Outputs: 2x Form C relays

• Power Consumption: 60 W typical

• Operating Temperature: 0°C to 45°C

• Dimensions: Standard chassis slot (approx. 220mm × 180mm)

Applications

This module is used in Alcatel‑Lucent edge routers, core switches, and optical transport systems, where it provides the brains and switching fabric for the entire chassis.

Redundancy and High Availability

When two CSM‑V2 modules are installed, they operate in active‑standby mode, with automatic failover in case of failure, ensuring zero‑service interruption.

Installation and Maintenance

Insert the module into the designated control slot, secure it, and connect management cables. The system automatically boots. Maintenance includes firmware upgrades, log reviews, and monitoring of health indicators.

Conclusion

The Alcatel‑Lucent 76‑0300‑02 CSM‑V2 PCB provides robust control and switching capabilities, essential for building resilient and manageable network infrastructure.
