There are two power supply inlets in the system (for redundancy). The system can operate with only one power supply connected. In
case the power supply is an FRU, a second power supply unit can be added to support hot-swap ability. Each power supply unit has a
single 2 color LED on the right side of the unit, that indicates the status of the unit.
