ExtremeSwitching™ 5520-12MW-36W Universal Edge Switch

1. Product Overview

The ExtremeSwitching 5520-12MW-36W is a high-performance, universal hardware switch designed for enterprise edge and aggregation deployments. This model combines 12 multi-rate (100M/1G/2.5G/5G) and 36 standard Gigabit Ethernet ports, all supporting 90W PoE (IEEE 802.3bt). As part of the versatile 5520 Series, it offers a flexible operating system choice between ExtremeXOS and VOSS, enabling advanced network segmentation, security, and automation features. Ideal for powering next-generation devices like wireless APs, PTZ cameras, and digital signage, this switch provides robust connectivity and power in a single platform.

2. Key Characteristics

• Universal hardware with dual-persona OS (ExtremeXOS or VOSS)
• 12 x 100M/1G/2.5G/5G Base-T and 36 x 10/100/1000Base-T ports, all with 90W PoE
• MACsec encryption on all access ports
• Up to 160Gb stacking (EXOS only) via QSFP28 ports
• Hot-swappable, redundant power supplies and fans
• Fabric Connect and IP Fabric support for automated network services
• Extended Edge Switching support for V300/V400 series devices
• Included 1-year ExtremeCloud IQ Pilot subscription

3. Core Technologies

The 5520-12MW-36W leverages advanced technologies including IEEE 802.3bt PoE for high-power device support, MACsec for link-level security, and Fabric Attach for automated service provisioning. It supports standards such as 10GBASE-X, 25GBASE-X, and Energy Efficient Ethernet (IEEE 802.3az). The switch also features Versatile Interface Modules (VIMs) for flexible uplink options including 10Gb and 25Gb connectivity.

4. Operational Principle

The switch operates as a centralized controlling bridge in network edge deployments. It processes traffic at wire speed using a non-blocking architecture, applying policies for security, QoS, and routing. When integrated with ExtremeCloud IQ, it enables zero-touch provisioning and remote management. The dual-persona capability allows the switch to boot with either ExtremeXOS or VOSS, dynamically adopting the feature set and management style of the chosen operating system.

5. Applications & Usage

The Extreme 5520-12MW-36W is ideal for:

• Enterprise campus networks requiring high-power PoE for IoT devices
• Aggregation layer switching in medium to large organizations
• Wired backbone for high-density wireless deployments
• Secure network segmentation in government or education sectors
• Digital signage and smart building infrastructure
