Powering down a DC-powered VNX series system
With the following exceptions
, you power down VNX series storage systems with DC
power as you would an AC system (documented on the EMC online support website
at:
http://mydocs.emc.com/VNX/)
After you stop all I/O activity to the storage system and, if necessary, unmount the file
systems:
VNX5100,
VNX5300, and
VNX5500
◆ To turn off disk processor enclosure power, push the power button on each power
supply and hold the button in for two seconds. Refer to Figure 6.

Allow the power supply to complete its shutdown sequence before removing the
power source. An orderly shutdown that flushes all cache can take up to several
seconds before the host sends a STOP to the power supply. We recommend that
you
wait two minutes before removing a power supply
from the DPE chassis.

VNX5400,
