Hardware Components
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 25.
AC Power Supply Unit
The AC power supply unit converts standard 220/110V AC 50/60 Hz to 5V DC at 5A, 12V DC at 3A. The
unit automatically senses the available voltage rating (110 or 220V) and no setting is required.
The AC power supply unit uses a standard AC220/110V connector. LED indicator is on the front panel and
indicates whether the AC unit is connected.
