To set the Client Authorization Control:
1. From any page, click the Configuration heading. The Configuration screen displays.
2. On the left-hand side of the screen, click Security.
Scroll to Client Authorization Control. In this section is a list of the IP addresses that are authorized to perform with
the Remote Management Unit for this specific autoloader. There are two sets of IP address boxes. You can individually
enable/disable and configure each set.
If enabled, each set can be used to specify either a range of IP addresses or a pair of specific IP addresses that
are allowed to administer this unit. A set can also be used to specify a single IP address if the desired IP address
is entered into both the "a" and "b" portions of the set. When a set is used to specify a range of IP addresses,
the "b" portion of each address set must be greater than or equal to the "a" portion of that address set.
If neither set is enabled, any IP client can administer the unit. If a single set is enabled, only clients that pass
the test specified by that set are allowed administrator access. If both sets are enabled, any client that passes
either of the two filter tests can administer the unit.
The Web server always allows any client to view the status information of the unit, regardless of the authorized client
list or the overlap control policy.
3. Use the drop-down box to select Enable or Disabled.
4. Type the IP addresses in the appropriate boxes.
5. Click submit to save.
NOTE: By entering an improper range of IP addresses, a user can possibly lock out all IP clients from administering the
autoloader. If this occurs, the user can restore the default values by running Restore Default from the front panel
Configuration menu.
Client Overlap Control is a management policy on controlling how the Web server handles overlapping control requests from
multiple clients on the authorized client list. The options include No Locking, Full Locking, and Time-Based Locking.
No Locking allows multiple clients to have unrestricted access to control the system as long as they are on the
authorized client list.
Full Locking permits only one authorized client to issue control requests at a time. This client must release the lock by
clicking the Home/Logout option in the upper frame of the page to permit other authorized clients to have control
access.
Time-Based Locking is similar to Full Locking in that only one authorized client can have control access at once, but
the lock is automatically released after the specified number of seconds of inactivity have elapsed.
After selecting the appropriate policy by clicking the check box, click submit to save the changes.
1. From any page, click the Configurations heading. The Configurations screen displays.
2. On the left-hand side of the screen, click Security.
3. Select a security option from the Client Overlap Control options:
No locking allows multiple users to access the system and issue requests.
