Power Supplies

The device has an internal power supply unit (AC unit) and a connector to connect the device to an
external power supply unit (DC unit). The external unit provides redundancy and is called an RPS unit.
To power up the device, only one power supply is required. Operation with both power supply units is
regulated through load sharing.
Load sharing is where the device power requirements are divided between the two power supplies. If one
power supply has an outage, the second power supply automatically continues providing power to the
whole device.
Power supply LEDs indicate the power supply status. For more information on LEDs, see "LED
Definitions" on page 27.
