## Long description

The Aruba J9991A switch module provides 20 ports of 10/100/1000BASE-T with PoE+ and 4 Smart Rate multi‑gigabit ports that support 1/2.5/5/10GBASE-T. Designed for use with the HP/Aruba 5400R zl2 switch series, the module enables copper‑based Ethernet connectivity up to 10 Gbit/s. Its compact size and 0.94 kg weight make it suitable for dense rack deployments and modular switch chassis.
Advantages
The module combines PoE+ on 20 gigabit ports with four multi‑gigabit ports, allowing mixed deployments of standard and higher‑speed copper devices without replacing cabling. Smart Rate multi‑gigabit support provides backward compatibility with 1G devices while enabling 2.5G/5G/10G links where supported. Built for the 5400R zl2 chassis, it integrates with existing management and power architectures and occupies a single module slot.
Suitable for
Enterprise access-layer deployments requiring PoE+ for IP phones, wireless access points and cameras
Environments needing multi‑gigabit copper uplinks or aggregation to servers and switches
Modular switch chassis installations where compact, hot‑swappable modules are required
