Extreme Networks offers universal hardware products that support more than one Network Operating System (NOS) personality. These hardware products ship with a default NOS personality but you can select a non-default personality. After you log in using the default NOS username and password for the first time, you can respond to an initialization question to change the NOS personality.

The following table identifies universal hardware products capable of running Fabric Engine and indicates the default NOS personality.

Network Operating System Selection

The primary method to select a NOS personality is by using ExtremeCloud IQ or ExtremeCloud IQ ‑ Site Engine. To select a NOS personality using ExtremeCloud IQ, see Read Me First – Universal Hardware. If the network is not accessible, or if you do not use Extreme Networks management software, you can also change the NOS personality manually by using CLI commands in the running NOS.

The procedure in this document includes the commands you use if the personality is Fabric Engine and you need to change the NOS personality manually. To change the personality to Fabric Engine, see the documentation for the running NOS.
