## Summary description

The HPE Aruba Networking 2540 48G PoE+ 4SFP+ is a managed L2 switch with 48 Gigabit Ethernet ports, PoE support, and a switching capacity of 176 Gbit/s. Ideal for enterprise networks requiring reliable connectivity and power delivery.

## Long description

The Aruba 2540 Switch Series is a Layer 2 access switch designed for mobile-first digital workplaces. It delivers entry-level campus and branch features with built-in 10GbE uplinks, PoE+ options, static and RIP routing, IPv6 support and no software licensing. The series is manageable via Aruba AirWave, Aruba ClearPass Policy Manager and cloud-based Aruba Central, enabling quick deployment and centralized monitoring of remote sites.
Advantages
The switch offers simplified deployment through Zero Touch Provisioning and automatic configuration when paired with Aruba access points for PoE prioritization, VLAN setup and rogue AP containment. It provides robust QoS and security controls, integrated wired/wireless management, and programmable REST API for automation. Built-in 10GbE uplinks and up to 370 W of internal PoE+ (on applicable models) improve edge performance and reduce congestion to aggregation/core layers.
Key specifications
Layer: Layer 2 access switch
Uplinks: Built-in 10GbE uplinks
Power over Ethernet: PoE+ models with up to 370 W internal PoE+ power
Routing: Static routing and RIP
IPv6: Supported
Management: Aruba Central (cloud), Aruba AirWave (on-premise), Aruba ClearPass Policy Manager
Automation: REST API programmable interface
Monitoring: RMON and sFlow
Security: 802.1X, MAC and Web authentication, RADIUS/TACACS+, ACLs, Port Security, MAC lockout, SSL
Licensing: No software licensing required
How to use
Install the Aruba 2540 in the access layer of your network and connect uplinks to aggregation or core switches using the built-in 10GbE ports. For PoE devices such as wireless access points and cameras use PoE+ model ports, observing total PoE budget limits. Manage devices centrally with Aruba Central for cloud-based provisioning or with Aruba AirWave for on-premise management. Use Zero Touch Provisioning for remote branches with limited IT staff; pair switches with Aruba access points to enable automated PoE priority, VLAN configuration and rogue AP containment. Configure authentication and security policies through Aruba ClearPass or the switch management interfaces.
Recommendations
Use Aruba Central or AirWave together with ClearPass Policy Manager to ensure unified wired and wireless policy enforcement. Choose a PoE+ model if you need to power multiple APs or IoT devices and verify the total PoE budget against connected device requirements before deployment.
