The Lenovo Storage V7000 Gen1 control enclosure contains two power supply units, each with an integrated battery. Each power supply unit can provide power to the whole enclosure.
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.
Table 1 identifies the LEDs in the rear of the control enclosure. Each power supply also contains fans that cool the enclosure. Cool air is drawn in through the front of the enclosure. The air passes over the drives, node canisters, and power supplies. The warmed air is ejected through the rear of each power supply. For optimal cooling, do not obstruct the airflow and ensure that all enclosure components or fillers are installed while the system is operational.
