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 Figure 5-78. After switchover, ensure that the ECM stops working (the yellow or red
indicator is on, or the green indicator is blinking) before you maintain it.
