ExtremeSwitching™ 5520-48W Universal Edge/Aggregation Switch

1. Product Overview

The ExtremeSwitching 5520-48W is a high-performance, universal fixed-form switch designed for enterprise edge and aggregation deployments. This 48-port switch combines robust connectivity with advanced Power over Ethernet (PoE) capabilities, supporting up to 90W per port (IEEE 802.3bt). It is part of the versatile 5520 Series, which offers a dual-persona architecture allowing users to select between ExtremeXOS or VOSS operating systems. Ideal for demanding environments, the 5520-48W provides secure segmentation, scalable stacking, and flexible uplink options.

2. Key Features

• 48 x 10/100/1000BASE-T ports with 90W PoE (IEEE 802.3bt)
• Dual-persona OS support (ExtremeXOS or VOSS)
• High-density PoE with 90W per port for advanced devices
• Modular uplink options via VIM slot (10Gb/25Gb)
• MACsec encryption on all access and uplink ports
• Up to 160Gb stacking with EXOS (8 units)
• Hot-swappable, redundant power and cooling
• Cloud or on-prem management via ExtremeCloud IQ

3. Core Technologies

The 5520-48W leverages advanced technologies including IEEE 802.3bt PoE, MACsec (256-bit encryption), Fabric Connect (VOSS) or IP Fabric (ExtremeXOS), and Energy Efficient Ethernet (IEEE 802.3az). It supports Layer 2/3 fabric services, automated provisioning, and high-availability features.

4. Operational Principle

The switch operates as a unified hardware platform with user-selectable OS personas. It can be pre-provisioned via ExtremeCloud IQ for zero-touch deployment. The 5520-48W uses non-blocking architecture to deliver wire-speed performance, while PoE management ensures efficient power allocation to connected devices.

5. Applications

Ideal for: enterprise wired/wireless aggregation, digital signage networks, IP surveillance systems, smart building infrastructure, campus networks, and high-density PoE environments such as conference rooms and educational facilities.
