During the transition period between Ruckus acquiring the Brocade switching platform some switches did not ship with a TPM module.
These can be identified by those with the Brocade logo on the switch.
Please note that the ICX range of switches are only manageable in SmartZone version 5
How to fix:
SSH to the SmartZone appliance and login using your admin credentials.
- enter your enable password set at the time of installation
