session will be preempted and specify how long the appliance will wait for the first user to
respond to the warning.

Click Setup > Preempt.

Enter a number of seconds in the Timeout Seconds field.
• If you enter a value of 0 to 4 seconds, the first user will not be warned before the
session is preempted.
• If you enter a value of 5 to 120 seconds, the first user will be warned and will be
allowed to continue using the target device for up to the amount of time in the
Timeout Seconds field. The session will be preempted when the user clicks OK, or
when the specified time elapses.
