After an ECM is inserted, active and standby switchover is supported only after the ECM
is configured and starts working properly (about 30 seconds).
This menu allows you to perform active/standby switchover on the UPS. When you need to
maintain an ECM and it is working, perform active/standby switchover on the ECM, as
shown in

indicator is on, or the green indicator is blinking) before you maintain it.
