ATI Access Levels
The unit has two access levels: Administrator and Operator. The access level
determines what functions are accessible, as shown in Table 5-1, Access Levels.
Access levels can be applied to Login IDs, the COM port, and Telnet sessions.
The effective access level is always the most restrictive:
When access is through the COM port and a login is required on the COM
port, the effective access level is the more restrictive of the COM port access
level or the login access level. (See Table A-7, Communication Port Options, in
Appendix A,
Configuration Options
.)
When access is through Telnet and a login is required for a Telnet session, the
effective access level is the more restrictive of the Telnet session access level
or the login access level. (See Table A-8, Telnet Session Options, in
Appendix A,
Configuration Options
.)
When an access level of Operator is applied to the COM port and Telnet
sessions, a Login ID with Administrator authority is effectively reduced to
Operator.
It is no longer possible to change configuration options, and full access
can only be restored by reloading factory defaults. (See
Resetting the Unit's COM
Port or Factory Defaults
on page 5-5.)
