Redundant VM/SI 3000 Manual Changeover
In a redundant VM/SI−3000 installation, changeover should occur automatically in the event of a fault. To make the change-
over manually, check the front panel “Active” LED to see which unit is active and which is in standby. To make the change-
over, press the “Activate” button on the standby unit.
