I upgraded my ICX 7150 firmware version from 08.0.90j to 08.0.95g using a USB flash drive as described here

After the upgrade, all my Wireless networks are functional.
But the switch doesn't seem to join the Unleashed network. Both the APs show connected and display information
On the Unleashed UI, I see the Switch as "Pending" with the message
The credential you provided is incorrect, please provide correct admin user name & password to try again...

I'm assuming that a typical upgrade does not wipe out credentials?
How can I get past this state for the switch.
