Universal Hardware Platform

The 5520 comes with a dual-persona capability, allowing you to choose

your OS. Either the Switch Engine (EXOS)1 or Fabric Engine (VOSS)2 OS can

be selected at switch start-up or changed at a later stage. When selected,

the switch assumes the features and capabilities of that OS.

5520 OS selection can also be automated with ExtremeCloud IQ so that

the desired OS can be automatically loaded at switch start-up, facilitating

remote OS enablement.

1 Switch Engine is the new name for ExtremeXOS (EXOS) on all universal

switch platforms, starting with Version 31.6.

2 Fabric Engine is the new name for the VSP Operating System Software

(VOSS) on all universal switch platforms, starting with Version 8.6.

Cloud-Based Network Management

The 5520 can be managed by ExtremeCloud IQ and ExtremeCloud IQ Site

Engine for centralized switch management, giving you a consolidated view

of users, devices, and applications across wired and wireless networks for

efficient inventory and network topology management. ExtremeCloud IQ

enables zero touch provisioning, allowing you to quickly bring new 5520

switches online as well as select the OS persona.

Alternatively, 5520 on-box management can be done manually via a web-

based GUI or generic command-line interface (CLI).

Ethernet Fabric Services

The 5520 supports a variety of Ethernet Fabric services, including Extreme’s

Fabric Connect when running Fabric Engine and Extreme’s IP Fabric

when running Switch Engine. It also supports Fabric Attach for automated

connection to either Layer 2 or Layer 3 Fabric services.

Extreme’s Fabric Connect and IP Fabric enable the creation of virtualized

networks that automate network operations, simplify network provisioning,

and enhance security, all while reducing the strain on network and IT

personnel.

Power over Ethernet (PoE)

All 5520 models support 30W, 60W, and 90W PoE that conforms with

IEEE 802.3bt. This enables the 5520 to address the needs of powered edge

devices, while eliminating the need for additional electrical cabling and

circuits. In addition, 5520 PoE models support perpetual and fast PoE for

even more efficient and reliable powered edge device operation

VIM Options for Flexible Uplinks

The 5520 supports Versatile Interface Modules (VIMs), providing flexible

uplink capabilities with a single VIM slot. VIM options include four-port

10Gb or 25Gb modules that include LRM and 256-bit MACsec support.

High-Performance Stacking

The 5520 Series supports high-speed 200Gb* stacking when running

Switch Engine via its two built-in QSFP28 stacking ports. Up to eight

systems can be stacked using qualified QSFP+ direct attach cables and

optical transceivers.

*200Gb stacking available with Switch Engine 31.6

Audio Video Bridging

The 5520 series supports IEEE 802.1 Audio Video Bridging (AVB) when

running Switch Engine OS. This allows 5520 models to deliver reliable, real-

time audio/video transmission over Ethernet, meeting the quality of service

required for today’s high-definition, time-sensitive multimedia streams.
