Implementing the Standby Power Mode
A major function of the PVA is implementing the standby power mode.
This mode removes dc power from all components except the EMU alarm
control switch. In the standby power mode the EMU alarm control switch
now functions as a dc power switch. Complete the procedure in Table 4–4
to place the subsystem in the standby power mode. Complete the procedure
in Table 4–5 to restore dc power to each enclosure.
