Standout Features
PoE+ with Strong Power Budget
The S2500-48P supports both 802.3af and 802.3at (PoE Plus) standards, delivering up to 30 W per port and dynamically managing power across the 400 W budget.
10 GbE Uplinks & Stacking Capability
Four integrated ports can operate as uplinks or used in ArubaStack configuration—stacking up to eight switches into a single logical unit with simplified management and up to 40 Gbps of stacking bandwidth.
Role-Based Policy Enforcement
When paired with Aruba ClearPass and Mobility Controllers, the Aruba Networks S2500-48P can dynamically enforce policies (VLANs, ACLs, QoS) per user or device—whether wired or wireless—ensuring seamless network experience and security.
Enhanced Layer 2/Layer 3 Functionality
This switch offers advanced networking features:
-
Ports: Auto MDIX, STP/RSTP/MSTP, VLANs, LACP, VLAN-based QoS, LLDP, CDP, etc.
-
L3 Routing: Static routes, OSPF support, MACsec, Jumbo frames (9,216 bytes), and a MAC table supporting up to 12,000 devices.
Management & Security Tools
Includes a console port, USB for configuration and firmware, LCD display, out-of-band Ethernet management, and support for SNMP v3, RADIUS, TACACS+, SSH, HTTPS, NTP, and IPv6 management.
Reliability & Warranty
Aruba provides a limited lifetime warranty with next-business-day hardware replacement, 24×7 TAC access for 90 days, and five-year coverage for power supplies and fans.
