Alcatel Lucent 108320 Module

The Alcatel Lucent 108320 Module is a power supply and distribution unit designed for use in OmniPCX and other Alcatel-Lucent communication systems. This module ensures stable and regulated DC power to all internal boards and components, playing a critical role in the overall reliability of the telephony infrastructure.

Power Output and Efficiency

Delivering a total output of up to 300W, the 108320 Module converts the main AC or DC input into multiple regulated voltages required by the system, such as +5V, +3.3V, and -48V. It features high-efficiency switching technology with over 90% efficiency, minimizing heat generation and reducing energy costs. The module also includes active power factor correction (PFC) to improve power quality and reduce harmonic distortion.

Protection and Safety Features

Built-in protection mechanisms include overvoltage, undervoltage, overcurrent, and short-circuit protection. The module automatically shuts down in fault conditions and restarts when the fault is cleared. Thermal sensors monitor internal temperatures, activating cooling fans or throttling output if necessary. These safety features ensure the longevity of both the power module and connected boards.

Hot-Swappable and Redundant Architecture

The 108320 Module supports hot-swappable operation, allowing replacement without interrupting system service. For critical installations, multiple modules can be configured in parallel to provide N+1 redundancy. Load sharing circuits distribute the current evenly, preventing single-point failures and enabling maintenance without downtime.

Compatibility and Form Factor

This module is designed to fit standard OmniPCX chassis slots, with a compact size of 6U height and 4HP width. It includes a robust backplane connector that mates with the system's power distribution bus. The unit is compatible with all OmniPCX 4400, Enterprise, and Office variants, as well as several media gateways and server platforms.

Monitoring and Diagnostics

Front-panel LEDs indicate input power, output status, and fault conditions. The module communicates with the system management controller via I2C, providing real-time voltage and current readings. Alarms are generated for over-temperature, fan failure, or output deviation, allowing administrators to proactively address issues.

Environmental Considerations

Designed for silent operation and low electromagnetic interference (EMI), the 108320 Module complies with international standards such as EN 55022, EN 60950, and IEC 61000. It operates within a temperature range of 0°C to 50°C and storage from -40°C to 70°C, making it suitable for standard equipment rooms.

Deployment and Maintenance

Installation is straightforward, requiring only mechanical insertion and connection of power cables. The module includes a removable air filter for easy cleaning. Regular firmware updates are available to optimize performance and enhance protection algorithms. Alcatel-Lucent provides a comprehensive service and support program for the 108320 Module, ensuring long-term operability.

Conclusion

The Alcatel Lucent 108320 Module is an essential component for maintaining stable and uninterrupted operation of communication systems. Its high efficiency, robust protection, and redundant design make it a reliable choice for enterprise voice networks, data centers, and telecommunications facilities.
