A major function of the PVA is implementing the standby power
mode. This mode removes dc power from all enclosure components,
except for the EMU alarm control switch. In standby power mode, the
EMU alarm control switch now functions as a dc power switch when
pressed. Complete the procedure in Table 4–4 to place the subsystem
into standby power mode. Complete the procedure in Table 4–5 to
restore dc power to each enclosure.
Some array controllers bypass the standby power mode
functionality from the PVA standby power switch. Refer to
the array controller documentation for availability of this
feature.
