Fan HPE JL669B network switch component 107mm width 51mm depth 41mm height

The HPE JL669B is a front-to-back fan tray designed for use in select Aruba and HPE network switch products. Measuring 107 mm wide, 51 mm deep and 41 mm high, this fan provides directed airflow to help maintain optimal operating temperatures for switch components and support reliable network performance.

Advantages

The fan tray offers a compact form factor compatible with specified HPE/Aruba switch models and delivers targeted front-to-back airflow. Its dimensions (107 × 51 × 41 mm) make it suitable for tight equipment bays while enabling effective heat dissipation to preserve component longevity and consistent switch operation.

Suitable for

• Replacement of defective or noisy fan trays in compatible Aruba/HPE switches
• Maintenance and spare parts for network infrastructure
• Deployments where front-to-back airflow is required for proper chassis cooling
