NOTE:
NOTE:
Stop I/O access to the system.
Close your applications running on the host computers to
stop all I/O access to the subsystem.
Flush the cache.
Locate the C_Dirty LED on the controller module to check

"Shutdown Controller" function in firmware to flush all
cached data. This prepares the RAID subsystem to be
safely powered down.
Turn off the power.

PSU. Once the subsystem is powered down, other
devices/enclosures that are connected to the subsystem
can be sequentially powered down.
