6. To enable or disable security for LOI, COM 1, and COM 2, click the radio button for the type
of security to be enforced:
• Disabled – All login requests are accepted.
•
User ID Enabled
– Login requests are accepted if the operator ID and password are valid
on the Model 3711. Upon successful login, full access is allowed to all ROCLINK 800
screens and functions.
• User Access Level Enabled – Login requests are accepted only if both of the following
are true:
- The operator ID and password are valid.
- The access level of the Model 3711 operator ID is equal to or higher than the access
level of the ROCLINK 800 operator ID.
Upon successful login, the access level of the ROCLINK 800 operator ID and the
Model 3711 operator ID are compared, and the user is limited to the lower access level.
Note: If security is enabled on any port, at least one user must be defined with access level 5.
3.3.3 Access level
For each operator ID, an access level is specified. The access levels control access to specific
ROCLINK 800 screens. Both ROCLINK 800 security and Model 3711 security use access levels.
Any access level implicitly includes all lower access levels; i.e., if access level 3 has been assigned to
an operator ID, that operator ID can also perform all actions that require access level 1 or 2.
Table 3-1 lists the ROCLINK 800 screens and the required access levels.
