Rack-mount security bezel kit HP 666988-B21-RFB for 2U servers

HP 666988-B21-RFB rack-mount security bezel kit is a front-panel accessory designed for 2U rack servers. The bezel provides a lockable cover that restricts physical access to front-facing drive bays and I/O ports while maintaining the server’s front appearance and airflow. Intended for datacenter and enterprise environments, this accessory helps reduce the risk of unauthorized drive removal and accidental access to critical components.

Advantages

The security bezel kit offers a keyed lock mechanism to secure drive bays and front I/O on compatible 2U servers, helping to prevent unauthorized removal of drives. As a factory-matched HP accessory, it integrates with the server’s front panel contours and preserves ventilation paths to maintain cooling performance. The bezel also contributes to a consistent, tidier rack appearance and simplifies physical security management by providing a single, lockable front barrier.

Suitable for

• 2U rack servers requiring front-panel physical security
• Datacenter and enterprise server racks with drive-based storage
• Environments needing to prevent unauthorized drive removal or tampering
• Deployments seeking a uniform front appearance while preserving airflow
