Alcatel Lucent GSX-K-FM-2W Fan Module

The Alcatel Lucent GSX‑K‑FM‑2W (also referenced as GSXKFM2W) is a high‑performance fan module used in Alcatel‑Lucent OmniSwitch chassis and other compatible platforms. This field‑replaceable unit provides high‑volume forced‑air cooling to maintain optimal operating temperatures for densely populated line cards, power supplies, and fabric modules. The module features multiple high‑speed fans with variable speed control, adjusting airflow based on real‑time thermal conditions to balance cooling capacity and acoustic output.

Overview

The GSX‑K‑FM‑2W is designed for chassis with front‑to‑back airflow orientation. It contains redundant fan elements to ensure continued cooling even if one fan fails. The module integrates temperature sensors and communicates with the chassis management controller to report fan speed, status, and fault conditions. It is typically installed in dedicated fan bays, with redundancy provided by additional modules in N+1 configurations.

Key Features

• High‑airflow capacity: > 150 CFM per module

• Variable speed fans with temperature‑based control

• Hot‑swappable for in‑service maintenance

• LED indicators for power, operation, and failure

• Redundant fan elements within the module

• Low vibration and long‑life ball‑bearing motors

• Compatible with OmniSwitch 9000 and 10000 series

Applications

This fan module is essential for high‑density chassis used in data centers, central offices, and enterprise core networks. It ensures reliable thermal management for systems handling heavy traffic loads, preventing overheating and ensuring component longevity.

Management and Monitoring

The GSX‑K‑FM‑2W provides real‑time status via the chassis management bus. Administrators can monitor fan speed, temperature, and health through CLI, web GUI, or SNMP. The module generates alerts for fan failure, over‑temperature, or removal, enabling proactive maintenance.

Installation and Maintenance

Installation is straightforward: slide the module into the designated fan bay until it locks, then secure with screws. The module automatically powers up and adjusts speed. Maintenance includes periodic cleaning of air intakes and replacing the module if a fan fault occurs. Hot‑swap capability allows replacement without interrupting system operation.

Conclusion

The Alcatel Lucent GSX‑K‑FM‑2W fan module delivers robust, intelligent cooling for demanding chassis environments. Its high airflow, redundancy, and hot‑swappability make it a reliable choice for maintaining operational integrity in critical networking infrastructure.
