Description
Aruba 2540 24G PoE+ 4SFP+ Switch
Designed for the digital workplace, the Aruba 2540 Switch Series is optimized for today’s mobile and IoT needs. The switches are easy to deploy, use and manage using Aruba AirWave or Aruba Central. Aruba ClearPass offers centralized security and external captive portal support.
The Aruba 2540 Switch Series provides a convenient and cost-effective wired access solution that can be quickly set up with Zero Touch Provisioning. PoE+ models deliver power across all access ports for wireless APs, security cameras, and other IoT devices.
The 2540 has wire-speed backhaul bandwidth capacity with built-in 10 GbE uplinks, robust QoS, static and RIP routing, IPv6 and includes a limited lifetime warranty with no software licensing required.
ENHANCED FEATURES
Software-defined networks
- Supports REST APIs to enable automation of network operations, monitoring, and troubleshooting
Unified Wired and Wireless
- Supports unified wired and wireless policies using Aruba ClearPass Policy Manager
- Switch auto-configuration automatically configures switches for different settings such as VLAN, CoS, PoE max power, and PoE priority when an Aruba access point is detected
- User Role defines a set of switch-based policies in areas such as security, authentication, and QoS. A user role can be assigned to a group of users or devices, using switch-based local user role or download from ClearPass
- Static IP Visibility allows ClearPass to do accounting for clients with static IP address
Quality of Service (QoS)
- Traffic prioritization (IEEE 802.1p) allows real-time traffic classification into eight priority levels mapped to eight queues
- Layer 4 prioritization based on TCP/UDP port numbers
- Class of service (CoS) sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
- Rate limiting sets per-port ingress enforced maximums and per-port, per-queue minimums
- Large buffers provide graceful congestion management
Connectivity
- Flexible 10 Gbps Ethernet with four built-in 10 Gigabit ports (SFP+)
- Auto-MDIX provides automatic adjustments for straight-through or crossover cables on all 10/100 and 10/100/1000 ports
- IEEE 802.3at Power over Ethernet (PoE+) provides up to 30 W per port that allows support of the latest PoE+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device; eliminates the cost of additional electrical cabling and circuits that would otherwise be necessary in IP phone and WLAN deployments
- Pre-standard PoE support detects and provides power to pre-standard PoE devices
- IPv6
- IPv6 host Enables switches to be managed in an IPv6 network
- Dual stack (IPv4 and IPv6) Transitions from IPv4 to IPv6, supporting connectivity for both protocols
- MLD snooping Forwards IPv6 multicast traffic to the appropriate interface
- IPv6 ACL/QoS Supports ACL and QoS for IPv6 network traffic
- IPv6 routing Supports static and RIPng protocols
- Security Provides RA guard, DHCPv6 protection, dynamic IPv6 lockdown, and ND snooping
Performance and Efficiency
- Energy-efficient design delivers power savings
- 80 PLUS Silver Certified power supply increases efficiency and savings
- Energy-efficient Ethernet (EEE) support reduces power consumption in accordance with IEEE 802.3az
