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 Series 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.

Management

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 (OOB) 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.

There is one Micro-B USB console port located on the front panel. If the Micro-B USB console port is connected, it is selected over the RJ45 serial console port. The Micro-B USB console port disconnects 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 are echoed to both the USB console and the RJ45 serial console port; however, no user input is accepted from the RJ45 serial console port.

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 labeled USB 1 and USB 2. They can host removable devices like flash drives.

Cooling

Switch cooling is provided by one replaceable fan module in 5420M switches, located on the rear panel of the switch, or two or three fixed fans in 5420F switches. Switch fans provide front-to-back airflow. 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

5420 Series switches use fixed and hot-swappable power supplies to provide enough power for the needs of the switch. 5420F models have 1 hot-swappable power supply and 1 fixed power supply. 5420M models have 2 hot-swappable power supplies. Power supply slots for hot-swappable power supplies are located in the rear of the switch. Power supplies are ordered separately.

Stacking Ports

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.

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 on page 28.

Operating Temperatures

All 5420 Series switch models support an operating range from 0°C to 50°C up to 3000 m (10,000 ft). Temperature restrictions apply for some models at high 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 IQTM (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.

Primary/Backup Switch Redundancy

When your stack is operational, one switch is the primary switch, responsible for running network protocols and managing the stack. To provide recovery in case of a break in the stack connections, you can configure redundancy by designating a backup switch to take over as primary if the primary switch fails. When you perform the initial software configuration of the stack, the “easy setup” configuration option automatically configures redundancy, with slot 1 as the primary and slot 2 as the backup. You can also configure additional switches as “primary-capable,” meaning they can become a stack primary in case the initial backup switch fails. When assigning the primary and backup roles in mixed stacks, consider the feature scalability and the speed of each switch model. The easy setup configuration process selects primary and backup switches based on capability and speed. The following list shows the capabilities based on the ability to cross stack with other switch families. The most capable switches are shown at the top of each list:

• 5520 Series 

• 5420 Series 

• 5320 Series

5420 Series switches can be stacked with themselves, or with 5320 Series or 5520 Series switches using Alternate stacking. The 5320 Series can only act as a Standby node in a 5420 Series Primary configuration. The 5320 Series cannot act as a Backup node when the Primary node is a 5420 Series. Beginning with Switch Engine 31.5, 5420 Series switches can be stacked with the 5520 Series switches using SummitStack-V80 and a special cable which converts QSFP+ to SFP-DD. The SummitStack-V80 configuration sets the speed of the QSFP+ stack ports to 20Gb. When easy setup compares two switches that have the same capability, the lower slot number takes precedence. Follow the same ranking hierarchy when you plan the physical placement of the switches in the stack.
