Aruba J9990A 20-port PoE+ / 4-port SFP+ zl2 Module | Enterprise Switching

Extend an Aruba 5400R zl2 chassis with a module built for mixed access and uplink demands. The J9990A combines 20 10/100/1,000Base-T PoE+ ports with 4 SFP+ slots, giving network teams a compact way to add powered edge connectivity and higher-speed fiber uplinks in the same expansion bay. This module is designed for environments that need more than basic port growth. PoE+ support helps power phones, access points, and other edge devices without separate adapters, while the SFP+ interfaces support 1 GbE and 10 GbE optical connections for aggregation or upstream links. MACsec support adds a security layer for traffic that must stay protected across the wire. For organizations standardizing on the 5400R zl2 platform, this module preserves chassis flexibility while increasing port density and uplink options. It is a practical fit for campus access layers, secure building networks, and mixed copper/fiber deployments where uptime, security, and expansion headroom matter.
