Clear faults before performing ECM active/standby switchover. For details about how to
clear faults, see Clear Faults in section 4.1.3.3 Alarms Screen.
After an ECM is inserted, active and standby switchover is supported only after the ECM
is configured and starts working properly (about 30 seconds).
When an ECM needs to be maintained, perform active/standby switchover on the ECM, as
shown in Figure 4-68 (a dialog box will display asking for confirmation to prevent
misoperations). After switchover, ensure that the ECM has stopped working (the yellow or red
indicator is on, or the green indicator is blinking) before maintaining it.
