The ExtremeSwitching 5720 Series is a family of high-performance, feature-rich edge and aggregation switches. As a universal hardware platform, the 5720 Series offers a user-selectable choice of Extreme‘s flagship switch operating systems, Switch Engine and Fabric Engine. The 5720 Series includes 24- and 48-port 1/2.5/5 Multi-gig models, as well as 24- and 48-port 1/2.5/5/10 Multi-gig models. All models offer 90W PoE support, including Perpetual PoE and Fast PoE. The 5720 Series includes 10/25Gb and/or 100Gb modular uplink options for flexible linkage to other switches or devices.
An RJ45 serial console port on the rear panel of the 5720 Series 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 is selected over the RJ45 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 rear panel RJ45 serial port; however, no user input is accepted from the rear panel port.
Tip
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.
Note
The first USB storage device inserted is mounted and can be used under the operating system as /usr/local/ext. A second inserted USB storage device is not used until the first one is removed.Each base model is available with front-to-back cooling.
Switch cooling is provided by replaceable fan modules. The available fan module uses airflow from front to back. Two modular power supply slots accommodate AC power supplies. Power supplies have integrated cooling fans that operate independently of the switch fan.
A spare fan module (XN-FAN-005-F) with front-to-back airflow is available for 5720 Series switches.
Two power supply bays accommodate modular AC power supplies. Power supplies have integrated cooling fans that operate independently of the switch fans. Like the fan modules, the power supplies are available in models with front-to-back cooling airflow. For more information about the power supplies used in the 5720 Series switches, see Power Supplies for Use with Your Switch.
Power supplies are ordered separately.
The following Versatile Interface Modules (VIM) are available for 5720 Series switches:
5720-VIM-2CE versatile interface module that provides two 100-GbE (QSFP28) MACsec capable ports.
5720-VIM-6YE versatile interface module that provides six 25-GbE (SFP28) MACsec capable ports.
Warning
The switch must be powered off before you install any VIM options. The interface module options are not hot swappable.
See Expansion Modules for more information regarding VIM modules.
Each 5720 unit comes equipped with two 100GbE stacking ports, also referred to as Universal Ethernet ports. When running Switch Engine, up to eight systems can be stacked using qualified QSFP28 direct attach cables and optical transceivers located on the front panel of the switch. QSFP28 passive direct attach cables can be used in the QSFP28 ports for stacking 5720s together using SummitStack-V400, as well as stacking 5720s and 5520s using SummitStack-V200.
Note
The two stacking/QSFP ports are “Universal Ethernet” ports, labeled “U1” and “U2.” These ports can operate either as stacking ports with Switch Engine or as Ethernet ports with Switch Engine and with Fabric Engine in non-fabric mode. When used as Ethernet ports, the U1 and U2 ports can support data rates of 100Gb, 2 x 50Gb (Switch Engine only), 1 x 40Gb, 4 x 25Gb, or 4 x 10Gb using QSFP+ optics.Use the disable stacking-support command to set the U1 and U2 ports in Ethernet mode.
When running Fabric Engine, the stacking (or Universal Ethernet) ports are reserved for use by advanced features on the switch by default. For more information, see the advanced-feature-bandwidth-reservation Boot Flag documentation in the Fabric Engine User Guide for your version of the Fabric Engine operating system located at https://www.extremenetworks.com/support/documentation/fabric-engine/.
Stacking cables for 5720 switches are ordered separately.
For information about QSFP28 and QSFP+ optical modules, see the Extreme Optics website.
All 5720 switch models support an operating range from 0°C to 50°C. Temperature restrictions apply for some models at high altitudes.
The ExtremeSwitching 5720 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 Switch Engine 32.1 Feature License Requirements .
For Fabric Engine licensing, see the Fabric Engine User Guide for your version of the Fabric Engine operating system located at https://www.extremenetworks.com/support/documentation/fabric-engine/.
