ExtremeSwitching 5420 Series Overview

The ExtremeSwitching 5420 Series is a family of high-performance, feature-rich edge switches designed for the next-generation digital enterprise. The 5420 Series universal hardware provides end-to-end secure network segmentation, in addition to advanced policy capabilities, and offers a user-selectable choice of Extreme‘s flagship switch operating systems. The 5420 is a uniquely flexible platform that can be deployed across a range of edge and wiring-closet environments.

The 5420 Series consists of 14 models in the 5420M and the 5420F families. The 5420M models include field-replaceable power supplies and fans, and 4 x 1/10/25Gb built-in uplink ports. The 5420F models have a fixed power supply and one or more fixed fans, a second field-replaceable power supply, and 4 x 1/10Gb built-in uplink ports.

Both the 5420M and the 5420F families include 24 and 48-port 1 Gigabit models, as well as 1 / 2.5 Gigabit multi-rate models. Both also provide 30/60/90W PoE capabilities making them an ideal wired backend for wireless APs or in support of next-generation power Ethernet devices, such as digital signage, pan-tilt-zoom cameras, smart lighting, or point-of-sale terminals.

The 5420 Series includes the following models:

Management

An RJ45 serial console port on the front panel of 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.

There is one Micro-B USB console port on the front panel. If the Micro-B USB console port is connected, it will be selected over the RJ45 console port. The Micro-B USB console port will disconnect when the switch is rebooted. You can re-connect the port if needed. When the Micro-B USB console is active, any messages from the switch to the client terminal will be echoed to both the USB console and the rear panel RJ45 serial port; however, no user input will be accepted from the rear panel port.
Note

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 steps

There are also two USB 2.0 Type A ports on the front panel. They can host removable devices like flash drives.

Cooling

Each base model is available with front-to-back cooling.

Switch cooling is provided by one replaceable fan module or two or three fixed fans. The available fan modules use airflow from front to back. Switch fans are not responsible for cooling the power supplies; power supplies have integrated cooling fans that operate independently of the switch fan.

A spare fan module (XN-FAN-000) with front-to-back airflow is available for 5420 Series switches.

Power Supplies

5420F models have 1 hot-swappable PSU and 1 fixed PSU. 5420M models have 2 hot-swappable PSUs. For more information about the power supplies used in the 5420 Series switches, see Power Supplies for Use with Your Switch.

Power supplies are ordered separately.

Stacking

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 and 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. Fabric Engine does not support stacking, but the U1 and U2 ports can be used as Ethernet ports by Fabric Engine when Fabric Engine is in non-fabric mode. When used as Ethernet ports, the U1 and U2 ports can support data rates of either 10Gb using SFP+ optics or 20Gb using SFP-DD optics. 5420M switch models support two 10Gb channels on each SFP-DD port when the ports are used as Ethernet ports on Switch Engine 31.6 and later. 5420F switch models support one 10Gb channel on each SFP-DD port when the ports are used as Ethernet ports

Stacking cables are ordered separately.

Secure Boot

Secure boot establishes a chain-of-trust relationship in the boot process. The chain-of-trust is established by cryptographic checks at each stage of the boot process to validate the integrity and authenticity of the next stage before it can execute. The current implementation validates boot images. It cannot be disabled after it has been programmed on the device. There is no command-line interface or commands to enable or disable secure boot. The status of the boot image verification can be monitored in the operating system.

For more information, see Secure Boot.

Operating Temperatures

All 5420 Series switch models support an operating range from -5°C to 50°C. Temperature restrictions apply for some models at higher altitudes.

Feature Licensing

The 5420 Series switches support Unified Licensing, so that you can use them with multiple operating systems. There are two methods of acquiring feature licenses: manual or through ExtremeCloud IQ™ (XIQ).

For Switch Engine licensing, see the Feature License Requirements for your version of the Switch Engine software.

For Fabric Engine licensing, see the Licensing chapter in the Fabric Engine User Guide for your version of the Fabric Engine operating system.

For XIQ licensing, see ExtremeCloud IQ.
