Tests that would jeopardize data transmission require taking the switch offline. If the
switch is not offline, a prompt is displayed before the test is allowed to proceed.
Note: Taking the switch offline disrupts switch operation.
Switch online
Pressing Enter while Switch online is selected activates the display shown in
Figure 45.
After the switch is offline, proceed with the test.
