Aruba S3500 Mobility Access Switch

The Aruba Networks™ S3500 Mobility Access Switch is a new class of product that brings role-based user access to wired networks.

Similar to other Aruba Mobility Access Switches, the S3500 is an integral part of the Aruba Mobile Virtual Enterprise (MOVE) architecture, which delivers secure virtualized access services to users, independent of their location, access method, device or application.

The S3500 is available in five models, including 24 and 48 10/100/1000BASE-T with optional power-over-Ethernet (PoE) or 24 1000BASE-X SFP ports.

Each model also supports an optional uplink module that provides an additional four Gigabit Ethernet/10 Gigabit Ethernet uplink and stacking ports. The PoE models are available with up to 30 watts per port based on the IEEE 802.3af PoE and IEEE 802.3at PoE+ standards.

Multiple Mobility Access Switches, including the S3500, may be interconnected to form an ArubaStack™.

This provides network connectivity for up to 384 Gigabit Ethernet devices such as virtual desktops, IP phones, videophones, classroom peripherals, medical devices, point-of-sale devices and security cameras as well as any 802.11n Wi-Fi access point (AP).

The S3500’s redundant power supply and modular, hot-swappable components make it ideal for high-density, high-availability wiring closets.
