ExtremeSwitching™ 5520-24T Universal Edge Switch
1. Product Overview
The ExtremeSwitching 5520-24T is a high-performance, fixed-form
switch designed for enterprise edge and aggregation deployments. As
part of the versatile 5520 Series, this model offers 24 Gigabit
Ethernet ports, advanced security features, and flexible management
options. It supports a dual-persona architecture, allowing users to
run either ExtremeXOS or VOSS operating systems, making it
adaptable to various network environments. These switches are built to deliver reliable, secure, and scalable connectivity
for modern digital enterprises.
2. Key Features
- 24 x 10/100/1000BASE-T ports with auto-sensing and MACsec support
- Dual-persona OS support (ExtremeXOS or VOSS)
- 1 x VIM slot for flexible uplink modules (10Gb/25Gb)
- 2 x QSFP28 stacking/uplink ports (unpopulated)
- Redundant, hot-swappable power supplies and fans
- 30W/60W/90W PoE support (on PoE models)
- Up to 8-unit stacking with 160Gb bandwidth
- Integrated with ExtremeCloud IQ for cloud or on-prem management
- Layer 2/3 Fabric services for secure segmentation
- Extended Edge Switching support for V300/V400 series devices
3. Core Technologies
The 5520-24T leverages advanced technologies including IEEE 802.3bt
PoE, MACsec encryption, Fabric Connect, and Energy Efficient
Ethernet (IEEE 802.3az). It supports high-speed stacking via QSFP28
ports and offers versatile uplink options through VIM modules.
These Extreme switches are designed to provide non-blocking, wire-speed
performance with robust security and automation capabilities.
4. How It Works
The 5520-24T operates as a fully managed Layer 2/3 switch. It can
be configured via CLI, web GUI, or through ExtremeCloud IQ for
zero-touch provisioning. The switch uses hardware-based forwarding
engines to ensure low latency and high throughput. It supports
virtualized network services, policy-based routing, and automated
fabric attachments, simplifying network operations and enhancing
security.
5. Applications
Ideal for enterprise edge, campus aggregation, and wiring closet
deployments. Commonly used in:
- Corporate and educational campuses
- Healthcare networks
- Retail and hospitality environments
- IoT and smart building infrastructure
- Wireless LAN backbone for AP connectivity
