===========================================
B2.0.1, Dec.29, 2022

Chg: Change-password is required if the current password is same as default.
     This rule does not apply to init-mode if troubleshooting is required.	

     Allow change password back to the same as factory default.
     So users can use a single password in site.
	  
Chg: For better protection, the non-isolated models may be discontinued in the future.
     Isolated version is actually shipped when ordering non-isolated models.

     Support isolated version without change the model name on web and eSearch Utility.
     For example: tM-7521_RevB isolated/non-isolated ==> all reports tM-7521_RevB
