## Summary description

The HPE Aruba Networking 2540 48G PoE+ 4SFP+ is a managed L2 switch with 48 Gigabit Ethernet ports and PoE capabilities. It features a switching capacity of 176 Gbit/s and supports various networking standards including IEEE 802.1AX and IEEE 802.1Q. Ideal for rack mounting, this 1U switch is designed for efficient network management and scalability, making it suitable for enterprise environments.

## Long description

The Aruba 2540 Switch Series is a Layer 2 access switch designed for the digital workplace and mobile users. It is optimized for enterprise campus, SMB and branch offices, offering built-in 10GbE uplinks, robust QoS, static and RIP routing, IPv6 support, and optional PoE+ models. The switch integrates with Aruba ClearPass Policy Manager, Aruba AirWave and cloud-based Aruba Central to simplify deployment, management and zero touch provisioning for remote or small sites.
Advantages
The Aruba 2540 provides automatic configuration when paired with Aruba access points, reducing setup time for PoE priority, VLANs and rogue AP containment. Cloud and on-premises management options (Aruba Central and AirWave) allow flexible operations without hardware changes. Low-latency Aruba ProVision ASIC, selectable queue configurations and internal PoE+ power up to 370 W support demanding edge use cases such as wireless APs, cameras and IoT devices.
Key specifications
Switch type: Layer 2 access switch
Uplinks: Built-in 10GbE uplinks
Routing: Static routing and RIP
Protocol support: IPv6
Power over Ethernet: PoE+ models with up to 370 W internal PoE+ power
Management: Aruba Central (cloud), Aruba AirWave (on-premises), ClearPass integration
ASIC: Aruba ProVision ASIC with low latency and adaptive power
Monitoring: RMON and sFlow
APIs: REST API for automation
Licensing: No software licensing required for core features
How to use
Connect the Aruba 2540 to your network aggregation or core using the built-in 10GbE uplinks, attach access ports for endpoints and, if required, power devices via PoE+. Use Aruba Central for cloud-based provisioning or AirWave for on-premises monitoring; alternatively integrate with ClearPass for unified wired and wireless policy enforcement. For remote deployments enable Zero Touch Provisioning to automatically apply configuration profiles and reduce on-site IT effort. Use the REST API and monitoring tools such as sFlow and RMON to automate and observe network behavior.
Recommendations
For branch and SMB deployments consider models with PoE+ if you plan to power APs, cameras or VoIP phones. Use Aruba Central or AirWave according to your operational model—cloud for minimal local IT, AirWave for on-premises control—and integrate ClearPass for consistent authentication and policy across wired and wireless users.
