Overview of the ExtremeSwitching 220 Series Switches

The ExtremeSwitching 220 series switches are 12-, 24, or 48-port switches that provide 10-gigabit Ethernet connectivity using fixed 10/100/1000BASE-T RJ45 ports and installable SFP+ optical modules. The ExtremeSwitching 220 series base models are described in the following sections:

Using a serial console port on the front panel of the switch, you can connect a terminal and perform local management. An Ethernet management port can be used to connect the system to a parallel 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.

The 12-port switches have a small form factor that allows you to install two switches side-by-side in a standard equipment rack.

Switch cooling is provided by one, two, or three non-replaceable fan modules with side-to-side airflow. AC power is supplied by a built-in power supply unit that is not user-replaceable.
