Summit X650 Series Switches

The Summit X650 series switches have 24 front-panel Ethernet ports that provide 10-gigabit Ethernet connectivity using fixed 10GBASE-T RJ45 ports or installable SFP+ optical modules. The Summit X650 series switches include the following base models:

The X650-24t switch requires an ExtremeXOS version of at least 12.2.1 but not greater than 15.3.x. The X650-24x switch requires an ExtremeXOS version of at least 12.2.2 but not greater than 15.3.x.

A serial console port on the front panel of the Summit X650 series switch allows you to 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 rear panel of the switch requires an installed versatile interface module or VIM. The following table lists the types of VIM available for the Summit X650 series switch.

The Summit X650 series switch must have an installed VIM; the switch will not operate correctly and enter into reboot loop without a VIM.


The Summit X650 switches require VIM1 or VIM3 modules. Other VIM types that may appear to be mechanically compatible with the Summit X650 switches will not function if they are installed in these switches.

Cooling is provided by a replaceable fan module. Two power supply bays accommodate either AC or DC power supplies.
