Extreme 7720 Series Switch Features on page 14
The Extreme 7720 Series is a purpose-built switch designed for high-performance
aggregation and core applications. The 7720 Series provides end-to-end secure
network segmentation and advanced policy capabilities. The 7720 Series is Universal
Hardware, providing a user-selectable choice of Extreme’s agship switch operating
systems.
The 7720 Series network hardware platform enables organizations to design networks
that accommodate a variety of applications and east-west trafc patterns. With its
high-density scale-out architecture, leading power efciency, and airow options, the
7720 Series platform 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 7720 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 conguration. The Ethernet
management port supports 10/100/1000 Mbps speeds.
Note
There is also a Type A USB 2.0 port that can host removable devices like ash
drives.
Cooling
Hot-swappable fan modules that provide either front-to-back or back-to-front airow
for switch cooling are available for 7720 Series switches. 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 airow in the fans and power supplies must be the
same.
