Hardware Description

Figure 2-8.
System LEDs
The following table describes the system LED indications.
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 devided between the two power supplies.
If one power supply has an outage, the second power supply automatically continues providing
power to the whole device.
