Ruckus Switch not able to connect

[Sam]

Hi team,

Good afternoon. Currently facing an issue which is not able to connect to my switch. It is disconnected from Unleashed portal. Ive try to ping the ip, however not able to. i can't find the info of the switch thru advance ip scanner, not even the mac address match. 
i try connect thru console cable, it prompt for user name and password.
Have tested below however all fail.

Usernames:           Passwords:

admin                    sp-admin

super                     Lennar

                               lennar

                               ruckus

                               Ruckus!

                               Ruckus1

                               admin

                               password

Is there anyway to by pass this? 
- what are the risk if i reset my switch? will all my existing ap configuration lost?
