## Long description

The HP Enterprise Aruba J9991A is a switch module for the 5400R zl2 Switch Series that provides 20 PoE+ ports at 10/100/1000BASE-T and 4 HP Smart Rate Multi‑Gigabit PoE+ ports supporting 1/2.5/5/10GBASE-T. The module supports copper Ethernet links up to 10 Gbit/s and is intended for use in modular chassis to expand powered and high‑speed connectivity. Note: MACsec is not available at first release.
Advantages
This module combines a high port density of 10/100/1000BASE‑T PoE+ ports with four multi‑gigabit PoE+ ports, enabling both legacy copper devices and newer higher‑speed endpoints to coexist on the same switch fabric. Compact dimensions and a 0.94 kg weight make it suitable for chassis installation without significant space or weight impact. Native support for 1/2.5/5/10GBASE‑T on four ports simplifies upgrades to multi‑gigabit edge devices.
Suitable for
Enterprise access layer deployments requiring PoE+ for IP phones, wireless APs, and cameras
Environments that need a mix of 1G and multi‑gigabit copper connections
Modular 5400R zl2 chassis where additional powered ports and higher‑speed uplinks are required
