The Extreme 8520 switches are purpose-built high density 1/10/25/40/100GbE fixed form factor switches designed for large scale data centers at service providers and large enterprise customers. They deliver scalable L2 and L3 resources with advanced features for network monitoring and network virtualization. The Extreme 8520 Series switch offers 48 1/10/25 GbE SFP28 ports and 8 100/40 GbE QSFP28 ports with 32 MB of packet buffer and an overall throughput of 2 Tbps in and out nonblocking switching capacity. SFP and QSFP ports offer a choice of speeds—including 100, 40, 25, 10, or 1 GbE—along with a wide choice of transceivers and cables. Ports can be mixed, offering flexible design options to cost-effectively support demanding data center and service provider environments.
The Extreme 8520 switches run Extreme Networks Extreme OS ONE operating system and the Extreme SLX-OS operating system.
Extreme OS ONE TM is a cloud-native network operating system (OS) based on a microservices architecture featuring in-service maintainability and is fully API driven for management programmability. Extreme OS ONE is a high-performance network operating system designed for data center, service provider, and enterprise networking environments.
The switch supports connections using the RJ45 serial console port or the Ethernet management port to view and manage the switch configuration. For more information on switch connection methods, see Manage Your Switch. For switch connection details, see Connect to a Management Console.

Note
There is also a Type A USB 2.0 port labeled USB on the front panel that can interface with USB storage devices.Each switch is cooled by hot-swappable field replaceable fan modules. The switch supports both front-to-back and back-to-front airflow for switch cooling. Switch fans are not responsible for cooling the power supplies; power supplies have integrated cooling fans that operate independently of the switch fan. Fans are ordered separately for base 8520-48Y-8C and 8520-48XT-6C switches. Fans are included with other switches.
For more information about the fan modules used in the switch, see Fan Modules for Use with Your Switch.
Each switch supports up to two hot-swappable modular AC or DC power supplies that provide enough power for the needs of the switch. Power supplies have integrated cooling fans that operate independently of the switch fans for power supply cooling and are not responsible for cooling the switch. Power supplies are ordered separately for base 8520-48Y-8C and 8520-48XT-6C switches. Power supplies are included with other switches.
For more information about the power supplies used in the switch, see Power Supplies for Use with Your Switch.
The operating temperatures and operating altitude for front-to-back airflow models are 0°C (32°F) to 50°C (122°F) at sea level; 0°C (32°F) to 40°C (104°F) up to 3000 m (10,000 ft). The operating temperatures and operating altitude for back-to-front airflow models are 0°C (32°F) to 45°C (113°F) at sea level; 0°C (32°F) to 40°C (104°F) up to 3000 m (10,000 ft).
