HPE Aruba J9988A SFP Expansion Module 24 Port

Detailed Specifications

The HPE J9988A is a high-density, 24-port Gigabit Ethernet SFP expansion module engineered for the Aruba 5400R zl2 Switch Series. It provides a robust solution for extending fiber optic connectivity in enterprise campus networks and data center environments, enabling flexible and scalable network aggregation. This module is specifically designed to address the need for secure, high-port-density fiber connections at the access or aggregation layer, offering a reliable foundation for connecting servers, storage, and other network infrastructure. A key technical differentiator of this module is its integrated MACsec (IEEE 802.1AE) encryption capability. This feature provides hardware-based, line-rate security, encrypting traffic at the link layer to ensure data confidentiality and integrity without impacting network performance. For organizations handling sensitive data, this layer of security is critical for regulatory compliance and protecting against unauthorized access, delivering end-to-end encrypted communication across the network infrastructure. Designed for seamless integration, the J9988A plugs directly into a compatible 5400R zl2 chassis, such as the 5406R or 5412R models. Its plug-in form factor simplifies deployment and allows for modular scalability, enabling network managers to add fiber ports as demand grows. Management is unified through the switch chassis's operating system, supporting standard CLI, web GUI, and integration with network management platforms like Aruba AirWave for centralized control and visibility.
