Changing the Network Operating System
ExtremeSwitching Universal Hardware switches can run two different operating systems: Switch Engine (formerly EXOS) (default) or Fabric Engine (formerly VOSS).
Making Your Initial Network Operating System Selection
You can make your initial selection of the operating system using:
- ExtremeCloud™ IQ (see ExtremeCloud IQ Agent Support)—You can select your network operating system when purchasing your switch, which associates the switch serial number with your desired network operating system, which then causes the desired network operating system to be loaded during ExtremeCloud onboarding. For more information about using ExtremeCloud IQ, go to https://www.extremenetworks.com/support/documentation/extremecloud-iq/.
- Extreme Management Center— see Extreme Management Center User Guide

Changing Your Network Operating System
You can change your network operating system selection at any time.
Caution
Changing your network operating systems deletes all configuration files, debug information, logs, events, and statistics information of the previous network operating system.Note
If you anticipate ever changing the operating system to Fabric Engine, and you want to statically assign IP addresses on the DHCP server, then it is recommended to assign them based on the DHCP client ID. For more information about this issue, see the Using a BOOTP or DHCP Server topic in the ExtremeXOS 31.7 User Guide .- ExtremeCloud IQ—See https://www.extremenetworks.com/support/documentation/extremecloud-iq/
