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 family 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.
An RJ45 serial console port on the switch enables you to connect a terminal and perform local management. An Ethernet management port can be used to connect the system to an out-of-band management network for administration. Alternatively, you can use an Ethernet cable to connect this port directly to a laptop to view and locally manage the switch configuration. The Ethernet management port supports 10/100/1000 Mbps speeds. The RJ45 serial console port is located on the front panel of the switch.
Note
Using a Micro-USB Type B to USB Type A cable, connect the Micro-USB Type B end to the switch, and the USB Type A end to a laptop or PC and complete the driver installation stepsYou can manage 4000 Series switches using Bluetooth with mobile devices or laptops. Bluetooth is enabled by default. 4000 Series switches support the Extreme Networks Bluetooth 5.0 dongle (XN-USB-BT500-ADAPTER). 4220 Series switches do not have a Bluetooth LED that displays Bluetooth status. See the 4000 Series User Guide for your version of Switch Engine for more detailed information on the 4000 Series Cloud-managed switches.
There is also a Type A USB 2.0 port labeled USB on the front panel that can host removable devices like flash drives.
Fixed internal switch fans in the 4220 Series provide left-to-right airflow for switch cooling. The internal fans are responsible for cooling the internal power supply.
Each 4220 Series 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. For power redundancy, switch models 4220-4MW-20P-4X and 4220-8MW-40P-4X support the addition of an external redundant power supply.
The external redundant power supply connection is located on the rear panel of the switch. The external redundant power supply can be rack-mounted. For more information about power supplies, see
Each switch comes equipped with two stacking ports, also referred to as Universal Ethernet ports. The stacking ports are labeled U1 and U2 and are located on the front of the switch. 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. The U1 and U2 ports operate as stacking ports by default. Use the disable stacking-support command to set the U1 and U2 ports in Ethernet mode.
Note
4220 Series switches can only be stacked with themselves.Stacking cables are ordered separately.
For information about optical modules, see the Extreme Optics website.
For information about stacking, see Build Stacks.
All 4220 Series switch models support an operating range from 0°C (32°F) to 50°C (122°F) up to 3000 m (10,000 ft).
Note
Models 4220-12P-4X, 4220-12T-4X, and 4220-4MW-8P-4X support silent mode operation at temperatures up to 35°C (95°F). Silent mode requires 1 RU of free space above the switch. Fans function normally if the temperature is between 35°C (95°F) and 50°C (122°F).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 software.
