ExtremeSwitching 5720 Series Overview
5720-24MW Switch Features on page 13
5720-24MXW Switch Features on page 14
5720-48MW Switch Features on page 15
5720-48MXW Switch Features on page 16
The ExtremeSwitching 5720 Series is a family of high-performance, feature-rich edge and aggregation
switches. As a universal hardware platform, the 5720 Series oers 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
oer 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.
Management
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.
There are also two USB 2.0 Type A ports: one on the front panel labeled USB and one on the rear
labeled USB. They can be used for a Bluetooth dongle or for attaching a removable memory module.
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.
ExtremeSwitching 5720 Series Hardware Installation Guide 11

Cooling
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.
Power Supplies
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 on page 19.
Power supplies are ordered separately.
Versatile Interface Module Options
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 o before you install any VIM options. The interface module
options are not hot swappable.
See Expansion Modules on page 21 for more information regarding VIM modules.
Stacking
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.
Cooling ExtremeSwitching 5720 Series Overview
12 ExtremeSwitching 5720 Series Hardware Installation Guide

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.
Operating Temperatures
All 5720 switch models support an operating range from 0°C to 50°C. Temperature restrictions apply
for some models at high altitudes.
Feature Licensing
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/.
For XIQ licensing, see Licensing Information.

Port Partitions
On some ExtremeSwitching switch models, you can configure QSFP28 and QSFP+ ports either as single
ports or as multiple, partitioned ports. In a partitioned port, with appropriate cabling, the original
physical port can accommodate multiple data lanes at lower bandwidths.
The following partitioning options are available:

Power Supplies for Use with Your Switch
715 W AC Power Supplies on page 19
1100 W AC Power Supplies on page 19
2000 W AC Power Supply on page 20
Each 5720 Series switch operates with two replaceable internal power supply units that provide all of
the power needed for the switch to operate. The power supply units must be a matched pair with the
same power rating, such as 750W, for long term use. You can remove one power supply without
interrupting the switch's operation. The 5720 Series can support an unmatched pair of power supply
units when you are upgrading or downgrading to matched pair with a dierent power rating.
