Storwize V7000 Gen1 power supply units for expansion
enclosures
The Storwize V7000 Gen1 expansion enclosure contains two power supply units
(PSU).
The two power supply units in the enclosure are installed with one unit top side
up and the other inverted. The power supply unit for the expansion enclosure has
four LEDs, two less than the power supply for the control enclosure.
There is a power switch on each of the power supply units. The switch must be on
for the power supply unit to be operational. If the power switches are turned off,
the power supply units stop providing power to the system.
