If Unisphere is not available and you need to change the management IP address, you need to press the password reset button on the back of either Storage Processor.  To change the IP address through which you access Unisphere:  1.  Use a tool (such as bent paperclip, pen, or small screwdriver) to press the password reset button. Hold for approximately 1 to 2 seconds, and then release the button. A few seconds later, the Fault LED turns a blue.  2.  Rerun the Connection Utility. After you configure the IP address, the Fault LED turns off.  3.  Log in to Unisphere using the default password for the admin account (Password123# ).  You can then follow the steps to reinitialize the system if you want to reset it back to factory.
