ExtremeSwitching 5520 Series: Universal Edge and Aggregation Platform
The ExtremeSwitching 5520 Series represents a high-performance, feature-rich family of fixed-form switches engineered for enterprise edge and aggregation deployments. These switches offer a versatile hardware platform that supports multiple operating systems—ExtremeXOS or VOSS—enabling advanced policy enforcement, end-to-end segmentation, and scalable fabric services. With flexible port configurations including Gigabit, Multi-Gigabit, and 10 Gigabit Ethernet, as well as high-power PoE options and scalable uplinks, the 5520 Series is built to support next-generation digital enterprises and IoT deployments.
Key Features
- Dual-persona OS support: Choose between ExtremeXOS or VOSS
- High-density PoE: Up to 90W per port (IEEE 802.3bt)
- Modular uplink options: 10Gb and 25Gb via VIM slots
- Secure connectivity: MACsec encryption on access and uplink ports
- Cloud or on-prem management: ExtremeCloud IQ or Site Engine
Core Technology
The 5520 Series leverages advanced Ethernet fabric technologies including Fabric Connect (VOSS) and IP Fabric (ExtremeXOS) for automated, secure network segmentation. It supports standards such as IEEE 802.3bt for PoE, IEEE 802.1AE for MACsec, and offers high-speed stacking capabilities up to 160Gbps with EXOS.
How It Works
The switch operates as a unified hardware platform that can be provisioned with either ExtremeXOS or VOSS. Upon boot, it connects to ExtremeCloud IQ for zero-touch deployment and persona selection. It supports Layer 2/3 forwarding, PoE power management, fabric automation, and secure encrypted links via MACsec.
Typical Applications
- Enterprise campus edge and wiring closet deployments
- Aggregation layer for mid-sized networks
- High-density wireless backhaul with PoE+ for APs
- IoT and digital signage infrastructure
- Secure government or healthcare networks with MACsec
