The ExtremeSwitching 5520 Series is a family of high-performance aggregation switches. The 5520 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 5520 Series includes 24- and 48-port 1 Gigabit models, 1/2.5/5 Gigabit multi-rate models, as well as a 24-port 10 Gigabit model. The family also offers 30/60/90W PoE, and supports 10G and 25G modular uplinks for flexible linkage to other switches or devices over a range of media.
The 10/100/1000Base-T ports on the 5520-24W/12MW-36W/48T/48W models can operate in half-duplex mode when operating at 10Mbps or 100Mbps. Half-duplex is not supported on these ports when operating at 1Gbps.
Both front-to-back and back-to-front airflow options for fan modules and power supply units are available in 5520 Series switches. All fan modules must have the same airflow direction and must match the airflow direction of the power supplies.
The 5520 Series includes the following models:
An RJ45 serial console port on the rear panel of the 5520 Series switch enables you to connect a terminal and perform local management. An Ethernet management port can be used to connect the system to a 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.
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 will be mounted and can be used under the operating system as /usr/local/ext. A second inserted USB storage device will not be used until the first one is removed.Switch cooling is provided by replaceable fan modules. Most 5520 Series models have fan modules that use airflow from front-to back. Models 5520-24T-BASE, 5520-24X-BASE, 5520-48T-BASE, and 5520-48SE-BASE require fan modules that use airflow from back-to-front. Power supplies also have integrated cooling fans that operate independently of the switch fan. All installed fan modules must blow air in the same direction and must match the airflow direction of the installed power supplies.
Fans are ordered separately for models 5520-24T-BASE, 5520-24X-BASE, 5520-48T-BASE, and 5520-48SE-BASE. Fans are included with other models.
Two spare fan modules, (17115) with front-to-back airflow, and (X870-FANBF, 17116) with back-to-front airflow, are available for 5520 Series switches.
Two power supply bays accommodate 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 or back-to-front cooling airflow. All installed power supplies must blow air in the same direction and must match the airflow direction of the installed fan modules.
Power supplies are ordered separately. For more information about the power supplies used in the 5520 Series switches, see Power Supplies for Use with Your Switch.
The following Versatile Interface Module (VIM) are available for 5520 Series switches:
5520-VIM-4X versatile interface module that provides four 10-GbE (SFP+) ports.
5520-VIM-4XE versatile interface module that provides four 10-GbE (SFP+) ports, LRM/MACsec capable.
5520-VIM-4YE versatile interface module that provides four 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.
Each 5520 unit comes equipped with two 40GbE stacking ports, also referred to as Universal Ethernet ports. When running Switch Engine, up to eight systems can be stacked using qualified QSFP28 and QSFP+ direct attach cables and optical transceivers located on the front panel of the switch. Standard 40 Gb Ethernet Optics and passive and active cables can be used in the QSFP28 ports for stacking 5520s together using SummitStack-V160.
High-speed 200Gb stacking is available on 5520 Series switches starting with Switch Engine 31.6 while using SummitStack V-200. The two QSFP ports on the 5520 Series each provide 50Gb in both directions, resulting in 4x50Gb, or 200Gb total. 5520 Series switches can stack only with themselves if you use SummitStack-V200.
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 http://documentation.extremenetworks.com/FABRICENGINE/SW/86/FabricEngineUserGuide/.
Stacking cables for 5520 switches are ordered separately.
For information about QSFP28 and QSFP+ optical modules, see the Extreme Optics website.
5520 switch models with front-to-back airflow support an operating range from 0°C to 50°C. Switch models with back-to-front airflow support an operating range from 0°C to 45°C. Temperature restrictions apply for some models at high altitudes.
The ExtremeSwitching 5520 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).
