Resetting Forgotten Administrative Password
You must have user credentials with Administrator privileges to perform management tasks. The CMC software has a user account
password protection security feature that may be disabled if the administrator account password is forgotten. If the administrator account
password is forgotten, it can be recovered using the J_PWORD jumper on the CMC board.
The CMC board has a two-pin password reset connector as shown in the following figure. If a jumper is installed in the reset connector,
the default administrator account and password is enabled and set to the default values of username: root and password:
calvin.
