Aruba S2500 Mobility Access Switch

The S2500 Mobility Access Switch from Aruba Networks® extends role-based user access, security and operational simplicity to wired networks.

A vital part of the Aruba Mobile Virtual Enterprise™ (MOVE) architecture, the S2500 delivers secure, virtualized access services to users, regardless of their location, access method, device or applications.

The S2500 is available in four models, with 24 or 48 10/100/1000BASE-T ports and power-over Ethernet (PoE) options.

Each model includes four fixed Gigabit Ethernet/10 Gigabit Ethernet uplink ports. Power-over-Ethernet (PoE) is available with up to 30 watts per port based on the IEEE 802.3af PoE and 802.3at PoE+ standards.

Mobility Access Switches can be interconnected to form an ArubaStack™. This provides connectivity for APs, virtual desktops, IP phones, videophones, classroom peripherals, medical devices, point-of-sale devices and security cameras.

The feature-richness of the S2500, along with its compact form factor and quiet operation, make it ideal for branch office and small office deployments.
