Extreme 8720 Overview

The Extreme 8720 switch is a high-performance feature-rich, fixed form factor switch built for service providers and data centers. The switch offers a versatile and efficient core/aggregation switching functionality for both campus and data center environments. The Extreme 8720 switch provides 32 40/100GbE QSFP+/QSFP28 ports and 128 25/10 GbE ports (using breakout cables) with 32 MB of packet buffer.

The Extreme 8720 switch runs Extreme Networks Extreme OS ONE operating system and the Extreme SLX-OS operating system.

Extreme OS ONE

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.

Management

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.

After connecting your switch, use the management functions built into the device to monitor the port status, physical status, and other information to help you analyze device performance and to accelerate system debugging. The device automatically performs a power-on self-test (POST) each time it is turned on.

There is also a Type A USB 2.0 port labeled USB on the front panel that can interface with USB storage devices.

Cooling

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 the base 8720-32C switch. 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.

Power Supplies

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 the base 8720-32C switch. 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.
