HPE Aruba J9991A PoE expansion module 24 Port

Detailed Specifications

The HPE J9991A is a high-density, multi-gigabit expansion module designed for the HPE Aruba 5400R zl2 Switch Series, targeting demanding enterprise campus and data center environments. Its primary function is to provide flexible, high-power PoE+ and high-speed copper connectivity to accommodate the latest generation of network devices. The module addresses the need for scalable bandwidth, enabling networks to support bandwidth-intensive applications and a growing number of IoT and wireless access points without replacing the entire chassis. This v3 zl2 module integrates twenty 10/100/1000BASE-T PoE+ ports alongside four HPE Smart Rate Multi-Gigabit ports, which support speeds of 1, 2.5, 5, and 10GBASE-T. This mixed-port configuration is crucial for environments with a diverse set of endpoint requirements, from standard IP phones and cameras to high-performance 802.11ac/ax Wi-Fi 6 access points. The inclusion of MACsec support provides standards-based Layer 2 security, ensuring data integrity and confidentiality on wired links. Engineered for seamless integration, the J9991A fits into any open slot of an HPE Aruba 5400R zl2 chassis, offering a scalable, pay-as-you-grow upgrade path. Its hot-swappable nature ensures network uptime during installation or maintenance. Management is unified through the switch chassis's operating system, accessible via CLI, Web GUI, and REST APIs, and can be centrally orchestrated using platforms like Aruba Central or AirWave for simplified, large-scale network administration.
