Universal Hardware Platform

The 7520 Series comes with a dual-persona capability allowing user choice

of the switch operating system (OS). Either the Switch Engine (EXOS) or

Fabric Engine (VOSS) persona can be enabled on 7520 hardware models.

The desired persona can be selected at start-up or changed at a later stage.

Once selected, the 7520 assumes the features/capabilities of the selected

OS.

7520 persona activation can be done manually at boot-up, including via the

system CLI. Or, it can be automated by pre-provisioning the 7520 persona

in ExtremeCloud IQ. When first booted, the 7520 automatically connects

to ExtremeCloud IQ to find its persona. The pre-provisioned OS persona

is then remotely enabled on the 7520 system – eliminating the need for

manual selection.

Ethernet Fabric Services

The 7520 supports a variety of Ethernet Fabric services, including Extreme’s

Fabric Connect when running Fabric Engine (VOSS) and Extreme’s IP

Fabric when running Switch Engine (EXOS). It also supports Fabric Attach

for automated connection to either Layer 2 or Layer 3 fabric services.

Extreme’s Fabric Connect and IP Fabric on the 7520 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.

High-Performance Stacking

Two of the 7520’s QSFP28 uplink ports can be used for high-speed 400Gb

stacking when running Switch Engine (EXOS). Up to eight systems can

be stacked using qualified direct attach cables and/or optical transceivers.

(Note: Stacking is not supported on the 7520-48YE -8CE model or when

running Fabric Engine (VOSS)).

Management

The 7520 can be managed by ExtremeCloud IQ and ExtremeCloud IQ-Site

Engine for comprehensive unified management with a consolidated view

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

Zero-touch provisioning from ExtremeCloud IQ lets one quickly bring new

7520 switches online as well as enable the selection of the operating

system (OS) persona. Alternatively, 7520 on-box management can be done

manually via a web-based GUI or generic CLI.
