## Long description

Modular network switch module designed for HP Aruba systems, offering twenty 10/100/1000BASE-T PoE+ copper ports plus four Smart Rate multi‑gigabit 1/2.5/5/10GBASE-T PoE+ copper ports. The module supports standard Ethernet rates (10/100/1000/10000 Mbit/s) and common copper standards (10BASE-T, 100BASE-TX, 1000BASE-T, 10GBASE-T). Its compact metal enclosure measures 261.6 × 20.65 × 44.5 mm and weighs 0.94 kg, enabling integration into compatible chassis or rack systems to provide PoE power delivery and planned MACsec v3 zl2 support for MAC‑layer encryption.
Advantages
This HP Aruba module consolidates a high density of PoE+ copper ports with four multi‑gigabit Smart Rate ports, allowing mixed-speed device connectivity on a single line card. The compact form factor and modest weight simplify installation into supported chassis. PoE+ capability across the copper ports enables powered devices such as IP phones and wireless access points to be supplied directly from the module. The design also includes planned MACsec v3 zl2 support for secure MAC‑layer encryption where enabled by platform firmware.
Suitable for
Enterprise access-layer aggregation for office LANs
VoIP phone deployments and PoE-powered wireless access points
Environments requiring mixed 1G and multi‑gigabit copper connectivity
Data closets and modular chassis installations in campus networks

How to use
Install the module into a compatible HP Aruba chassis slot following the chassis installation procedures and safety guidelines from the platform documentation. After mechanical installation, connect copper Ethernet cables to the 10/100/1000BASE-T and multi‑gigabit ports as required. Configure PoE settings, link speeds and VLANs through the switch management interface or network controller. Verify power budgets for PoE+ devices and monitor port status and link negotiations to ensure expected performance. Consult the platform release notes regarding MACsec availability and firmware requirements before enabling MAC-layer encryption.
Usage recommendations
Use the multi‑gigabit 1/2.5/5/10GBASE-T ports for uplinks or for devices that require speeds above 1 Gbit/s. Plan PoE power allocation according to the total connected load to avoid exceeding the chassis power budget. Check platform documentation for firmware updates and MACsec enablement details before relying on MAC-layer encryption.
