4220 Cloud Managed Switch Overview

The 4000 Series are ExtremeCloud IQ managed Layer 2 switches that are fully cloud managed. The 4000 Series maintains all the power and flexibility of a traditional enterprise access switch, while simplifying network operations. Visibility is centralized and actions are instantaneous. Zero-touch provisioning allows rapid deployment across sites, and machine learning tools help quickly isolate issues when troubleshooting. The 4000 Series also provides support for stacking and PoE.

Note

An ExtremeCloud IQ Pilot license is required for each 4000 Series switch.

The 4220 Series includes 8, 12, 24, and 48-port models with gigabit and multi-gigabit (1/2.5/5Gb) access ports, up to 90W PoE, and 4 x SFP+ uplink/stack ports and is a highly flexible enterprise Layer 2 wired edge solution.

Management

Each switch can be flexibly managed though the cloud, the network, or the command-line interface (CLI), either remotely or locally. The switch supports any of the following management methods:

ExtremeCloud IQ through the cloud or over the network.
an out-of-band management network connected to the Ethernet management port on the switch.
a laptop connected directly to the Ethernet management port on the switch through an Ethernet cable.
a terminal connected to the RJ45 serial console port on the switch.
a PC or laptop connected to the Micro-B USB console port on the switch.
a mobile device or a laptop using Bluetooth with a Bluetooth dongle connected to the USB Type A port on the switch.

For more information about switch management, see Manage Your Switch.

Note

There is also a Type A USB 2.0 port labeled USB on the front panel that can host removable devices like flash drives.

Cooling

Each switch is cooled by fixed internal switch fans with left-to-right airflow. The switch fans are responsible for cooling the internal power supply; the power supply does not have an integrated cooling fan that operates independently of the switch fan for power supply cooling.

Power Supplies

Each switch has a fixed internal AC power supply that provides enough power for the basic power needs of the switch. For switch models that support PoE, the internal power supply also provides a POE power budget beyond the basic switch needs. The power supply has an integrated cooling fan that operate independently of the switch fans for power supply cooling.

See Power Specifications for more information about PoE for the switch.

For power redundancy, switch models 4220-4MW-20P-4X and 4220-8MW-40P-4X support the addition of an external redundant AC power supply that can be rack-mounted. The external redundant power supply connection is located on the rear panel of the switch.

The external redundant power supply is ordered separately

For more information about the external redundant power supplies, see Redundant Power Supplies for Use with Your Switch.

Stacking Ports

Each switch comes equipped with two stacking ports, also referred to as Universal Ethernet ports. When running Switch Engine, these ports can be used in either stacking mode or Ethernet mode. When in stacking mode, up to eight systems can be stacked using qualified direct attach cables or optical transceivers. Fabric Engine does not support stacking; the stacking ports can be used as Ethernet ports if Fabric Engine is in non-fabric mode.

Note

The 4220 Series switches can only stack with themselves.

Stacking cables are ordered separately.

For more information about stacking ports, see Universal Ethernet Ports.

For information about optical modules, see the Extreme Optics website.

Operating Temperatures

The 7520 supports the following operating temperatures with front-to-back cooling:

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 7520 supports the following operating temperatures with back-to-front cooling:

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)

Feature Licensing

A base license for the 4220 Series is the only license supported in Switch Engine. For additional Switch Engine licensing information see the Feature License Requirements for your version of the Switch Engine operating system.
