Storwize V7000 Gen1 Power supply unit and battery for the
control enclosure
The Storwize V7000 Gen1 control enclosure contains two power supply units, each
with an integrated battery.
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 control enclosure has six
LEDs.
Each power supply unit has a power switch. The switch must be on for the power
supply unit to be operational. If the power switches are turned off, or the main
power is removed, the integrated batteries temporarily continue to supply power
to the node canisters. As a result, the canisters can store configuration data and
cached data to their internal drives. Battery power is required only if both power
supply units stop operating.
Figure 18 shows the location of the LEDs ▌1▐ in the rear of the power supply unit.
Table 9 identifies the LEDs in the rear of the control enclosure.
