Power Supplies

Each storage enclosure contains two power supplies. These power supplies provide
power to the other components in the enclosure by converting incoming AC voltage to
DC voltage. The power supplies are redundant: if one supply fails, the other power
supply can keep the enclosure running until the failed unit can be replaced. Each power
supply has the following components on its rear panel (see Figure 2-7):

•

Locking lever

•

AC power input connector

•

Power switch

•

Power light

•

Fault light

During normal operation, the power light is illuminated. If there is a problem with the
power supply, the fault light comes on.

For specification information about the power supplies, see “Wiring and Power” on
page 93.
