Change the Network Operating System Personality
Use this procedure on a Fabric Engine switch to change the Network Operating System (NOS) personality.
The primary method to select a NOS personality for the switch is by using ExtremeCloud IQ. If the network is not accessible, or if you do not use Extreme Networks management software, you can change the NOS personality by using Fabric Engine CLI commands.
Before you begin
Use FTP to transfer the NOS image to the /intflash/ directory.
About this task
If you change the NOS personality, the system deletes all configuration, licensing, and log files that pertain to the previous NOS personality.
If a power interruption occurs during a personality change, the system restarts the process after you restore power to the switch.
As part of the NOS personality change, you must restart the switch. If, during the restart, the system detects a failure, the NOS personality does not change. After the original NOS restarts, it logs an error message and raises a persistent alarm.
Note
This procedure does not provide information about upgrading Fabric Engine. For details about upgrading the Fabric Engine release, see Upgrade the Software.
Procedure
Example
