The Extreme7520 Seriesare purpose-built 48-port 10Gb and 48-port 25Gb switches designed for high-performance aggregation and core applications. The Extreme 7520 provides end-to-end secure network segmentation and advanced policy capabilities. The7520 Seriesare Universal Hardware, providing a user-selectable choice of Extreme's flagship switch operating systems.
The7520 Seriesnetwork hardware platform enables organizations to design networks that accommodate a variety of applications and east-west traffic patterns. With its high-density scale-out architecture, leading power efficiency, and airflow options, the7520 Seriesplatform delivers a cost-effective solution that optimizes power, cooling, and equipment room space, wherever your network operating center might be.
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 also a Type A USB 2.0 port that can host removable devices like flash drives.
Cooling
Hot-swappable fan modules that provide either front-to-back or back-to-front airflow for switch cooling are available for7520 Seriesswitches. The six fan slots on all models are located on the rear panel. Switch fans are not responsible for cooling the power supplies; power supplies have integrated cooling fans that operate independently of the switch fan. The direction of the airflow in the fans and power supplies must be the same.
Fans are ordered separately for basemodels7520-48Y-8C,7520-48YE-8CEand7520-48XT-6C. Fans are included with other models.
Power Supplies
Hot swappable 800 W AC or DC power supplies are available to power the switch. The power supplies have integrated cooling fans that operate independently of the switch fans. The fans provide either front-to-back or back-to-front airflow. The direction of the airflow in the power supplies and the switch fans must be the same. The two power supply slots on all models are located on the rear panel.
Power supplies are ordered separately for the basemodels7520-48Y-8C,7520-48YE-8CEand7520-48XT-6C. Power supplies are included with other models.
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.By default the stacking ports operate as Ethernet ports. Use theenable stacking-supportcommand to set the stacking ports in stacking mode.The stacking ports on 7520-48XT-6C models are ports 53 and 54. The stacking ports on 7520-48Y-8C models are ports 55 and 56.
When runningFabric 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 theFabric Engineoperating system.
