account name and the corresponding password. The default user accounts and passwords for each access level are listed in Table 5 "User Access Levels" (page 141).

Note: The default Administrator user password can be changed during the initial configuration. For the Operator user, the Boot user, and the Root user however, the default passwords are used even after the initial configuration. It is therefore recommended that you change the default NVG passwords soon after the initial configuration, and as regularly as required under your network security policies. For more information about how to change a user account password, see “Changing a Users Password” (page 88).
