The ExtremeSwitching 5520-48SE is a high-performance, universal hardware switch designed for enterprise edge and aggregation deployments. It features 48 x 100M/1Gb SFP ports, MACsec encryption, and flexible uplink options via a VIM slot. Supporting dual-persona OS operation (ExtremeXOS or VOSS), this switch offers advanced Layer 2/Layer 3 fabric services, high availability with redundant power and cooling, and is managed seamlessly via ExtremeCloud IQ. Ideal for secure, scalable network segmentation.
The 5520-48SE leverages advanced switching technologies including IEEE 802.3 standards for Ethernet, IEEE 802.3az for Energy Efficient Ethernet, and IEEE 802.1AE for MACsec encryption. It supports Fabric Connect (VOSS) and IP Fabric (ExtremeXOS) for automated, secure network segmentation and virtualization.
The switch operates as a non-blocking, wire-speed device, processing frames at up to 517.8 Mpps. It uses hardware-based forwarding engines and QoS policies to ensure low latency and high throughput. The dual-personality OS allows the switch to boot into either ExtremeXOS or VOSS, enabling feature sets tailored to fabric or traditional IP networking.
Ideal for enterprise campus networks, data center aggregation, and secure wiring closets. Commonly used in:
